Joint articulations

cubitoradial

Pertaining to the ulna and the radius Where the Ulna & radius connect.

radioulnar

Pertaining to the ulna and the radius Where the Ulna & radius connect.

cuneonavicular

The Cuneonavicular articulation is a joint in the human foot. It is formed between the navicular and the three cuneiform bones. The navicular and cuneiform bones is connected by dorsal and plantar ligaments.

acromioclavicular

The acromioclavicular joint, or AC joint, is a joint at the top of the shoulder. It is the junction between the acromion (part of the scapula that forms the highest point of the shoulder) and the clavicle. It is a plane synovial joint.

atlantoaxial

The atlanto-axial joint is a joint between the first and second cervical vertebrae.

calcaneocuboid

The calcaneocuboid articulation is the joint between the calcaneus and the cuboid bone.

costochondral

The costochondral joints are the joints between the ribs and costal cartilage in the front of the rib cage. They are hyaline cartilaginous joints (i.e. synchondroses).

Cricoarytenoid

The cricoarytenoid articulation (or joint) is a joint connecting the cricoid cartilage and the arytenoid cartilage.

tibiofibular

When the term "tibiofibular articulation" is used without a modifier, it refers to the proximal, (also called superior tibiofibular joint) and not the distal tibiofibular articulation (Inferior tibiofibular joint).

manubriosternal

the early union, by hyaline cartilage, of the manubrium and the body of the sternum, which later becomes a symphysial type of joint. Synonym(s): synchondrosis manubriosternalis

patellofemoral

Joint, patellofemoral: One of the knee joints. The knee has three parts. The thigh bone (femur) meets the large shin bone (tibia) forming the main knee joint. This joint has an inner (medial) and an outer (lateral) compartment. The kneecap (patella) and the femur form a third joint, called the patellofemoral joint.

cuneocuboid

Relating to the lateral cuneiform and cuboid bones. The synovial articulation between the lateral surface of the lateral cuneiform and the anterior two thirds of the medial surface of the cuboid.

sacroiliac

See - iliosacral

intercarpal

The intercarpal articulations (articulations of the carpus) can be subdivided into three sets of articulations: Those of the proximal row of carpal bones, those of the distal row of carpal bones, and those of the two rows with each other.

metacarpophalangeal

The metacarpophalangeal joints (MCP) refer to the joints between the metacarpal bones and the phalanges of the fingers. That means the MCP joint is the knuckle between the hand and the finger. These are of the condyloid kind, formed by the reception of the rounded heads of the metacarpal bones into shallow cavities on the proximal ends of the first phalanges, with the exception of that of the thumb, which is a ginglymus.

talonavicular

The talonavicular joint is the lowest of the three ankle joints, spanning to the mid-foot. Articulation between the talus and navicular.

incudomalleolar

Incudomalleolar joint or articulatio incudomallearis is a small synovial joint between the malleus (hammer) and the incus (anvil). The joint's function is to transfer vibrations between the ossicles in the middle ear, which is perceived as sound. Contrary to other synovial joints the moment is very limited and is usually only of springy character. All of the ossicles move as a unit. When the eardrum is moved inward due to sound vibrations, transferred through the outer ear, it transmits to the handle or manubrium of the malleus which is connected to the ear drum. The head of the malleus (caput mallei) moves with it and transfers energy/movement to the corpus of the incus (corpus incudis), which is located directly behind. The sound vibrations is then transferred to the stapes (stirrup) through the incudostapedial joint. When the ear drum moves inwards so does all of the ossicles and the oval window.

incudostapedial

Incudostapedial joint or articulatio incudostapedia is a small synovial joint between the incus (anvil) and the stapes (stirrup). The joint's function is to transfer vibrations between the ossicles in the middle ear, which is perceived as sound. Contrary to other synovial joints the moment is very limited and is usually only of springy character. All of the ossicles move as a unit. The incudostapedial joint lies between the long leg (long crus or crus longum incudis) and the head of the stapes (caput stapedis). When the eardrum is moved inward due to sound vibrations, transferred through the outer ear, it transmits to the malleus and then to the incus via the incudomalleolar joint. The long leg (long crus or crus longum incudis) moves with the rest of the incus and a small knob, the lenticular process, articulates with the head of the stapes. The stapes then transfers the vibration to oval window.

carpometacarpal

The carpometacarpal (CMC) joints are five joints in the wrist that articulate the distal row of carpal bones and the proximal bases of the five metacarpal bones.

costovertebral

The costovertebral joints are the articulations that connect the heads of the ribs with the bodies of the thoracic vertebrae. Joining of ribs to the vertebrae occurs at two places, the head and the tubercle of the rib. Two convex facets from the head attach to two adjacent vertebrae. This forms a synovial planar (gliding) joint, which is strengthened by the ligament of the head and the intercapital ligament. Articulation of the tubercle is to the transverse process of the adjacent vertebrae. This articulation is reinforced by the dorsal costotransverse ligament.

cricothyroid

The cricothyroid articulation (or joint) is a joint connecting the cricoid cartilage and the thyroid cartilage. It plays a key role in adjusting human voice pitch by changing the tension of the vocal cords. This tension is controlled mostly by the endolaryngeal vocalis and the extralaryngeal cricothyroid muscles which change vocal fold tension by narrowing the cricothyroid space created by rotation and gliding movements in horizontal and vertical direction allowed for by the cricothyroid articulation

distal radioulnar

The distal radioulnar articulation (inferior radioulnar joint) is a joint between the two bones in the forearm; the radius and ulna. It is one of two joints between the radius and ulna, the other being the proximal radioulnar articulation. The distal radioulnar articulation is the one of the two closest to the wrist and hand. The distal radioulnar articulation pivot-joint formed between the head of ulna and the ulnar notch on the lower extremity of radius.

distal tibiofibular

The distal tibiofibular joint (tibiofibular syndesmosis) is formed by the rough, convex surface of the medial side of the distal end of the fibula, and a rough concave surface on the lateral side of the tibia. It should not be confused with the superior tibiofibular joint, which is the only synovial tibiofibular joint, and is sometimes simply called the "tibiofibular articulation".

humeroradial

The humeroradial joint is the joint between the head of the radius and the capitulum of the humerus, is a limited ball-and-socket joint, hinge type of synovial joint. The bony surfaces would of themselves constitute an enarthrosis and allow movement in all directions, were it not for the annular ligament, by which the head of the radius is bound to the radial notch of the ulna, and which prevents any separation of the two bones laterally. The annular ligament secures the head of the radius from dislocation, which would otherwise tend to occur, from the shallowness of the cup-like surface on the head of the radius. Without this ligament, the tendon of the biceps brachii would be liable to pull the head of the radius out of the joint. The head of the radius is not in complete contact with the capitulum of the humerus in all positions of the joint. The capitulum occupies only the anterior and inferior surfaces of the lower end of the humerus, so that in complete extension a part of the radial head can be plainly felt projecting at the back of the joint. In full flexion the movement of the radial head is hampered by the compression of the surrounding soft parts, so that the freest rotatory movement of the radius on the humerus (pronation and supination) takes place in semiflexion, in which position the two articular surfaces are in most intimate contact. Flexion and extension of the elbow-joint are limited by the tension of the structures on the front and back of the joint; the limitation of flexion is also aided by the soft structures of the arm and forearm coming into contact.

humeroulnar

The humeroulnar joint (ulnohumeral or trochlear joint), is part of the elbow-joint. It composed of two bones, the humerus and ulna, and is the junction between the trochlear notch of ulna and the trochlea of humerus. It is classified as a simple hinge-joint, which allows for movements of flexion, extension and circumduction. Owing to the obliquity of the trochlea of the humerus, this movement does not take place in the antero-posterior plane of the body of the humerus. When the forearm is extended and supinated, the axis of the arm and forearm are not in the same line; the arm forms an obtuse angle with the forearm, known as the carrying angle. During flexion, however, the forearm and the hand tend to approach the middle line of the body, and thus enable the hand to be easily carried to the face. The accurate adaptation of the trochlea of the humerus, with its prominences and depressions, to the trochlear notch of the ulna, prevents any lateral movement. Flexion in the humeroulnar joint is produced by the action of the biceps brachii and brachialis, assisted by the brachioradialis, with a tiny contribution from the muscles arising from the medial epicondyle of the humerus. Extension in the humeroulnar joint is produced by the triceps brachii and anconeus muscle, with a tiny contribution from the muscles arising from the lateral epicondyle of the humerus, such as the extensor digitorum muscle.

interphalangeal

The interphalangeal articulations of the hand are the hinge joints between the phalanges of the hand (i.e. the finger bones). There are two sets (except in the thumb): "proximal interphalangeal joints" (PIJ or PIP), those between the first (also called proximal) and second (intermediate) phalanges "distal interphalangeal joints" (DIJ or DIP), those between the second and third (distal) phalanges Anatomically, the proximal and distal interphalangeal articulations are very similar. There are some minor differences in how the volar plates are attached proximally and in the segmentation of the flexor tendon sheath, but the major differences are the smaller dimension and reduced mobility of the distal joint.

proximal radioulnar

The proximal radioulnar articulation (superior radioulnar joint) is a synovial trochoid or pivot joint between the circumference of the head of the radius and the ring formed by the radial notch of the ulna and the annular ligament.

proximal tibiofibular

The proximal tibiofibular articulation (also called superior tibiofibular joint) is an arthrodial joint between the lateral condyle of the tibia and the head of the fibula. The contiguous surfaces of the bones present flat, oval facets covered with cartilage and connected together by an articular capsule and by anterior and posterior ligaments. When the term "tibiofibular articulation" is used without a modifier, it refers to the proximal, and not the distal tibiofibular articulation = Inferior tibiofibular joint.

radiocarpal

The radiocarpal joint is formed by the radius, radioulnar disk, and 3 bones in the proximal carpal row: the scaphoid, lunate, and triquetrum.

iliosacral/sacroiliac

The sacroiliac joint or SI joint (SIJ) is the joint in the bony pelvis between the sacrum and the ilium of the pelvis, which are joined by strong ligaments. In humans, the sacrum supports the spine and is supported in turn by an ilium on each side. The joint is a strong, weight bearing synovial plane joint with irregular elevations and depressions that produce interlocking of the two bones. The human body has two sacroiliac joints, one on the left and one on the right, that often match each other but are highly variable from person to person

glenohumeral

The shoulder joint is a multiaxial synovial ball and socket joint and involves articulation between the glenoid cavity of the scapula (shoulder blade) and the head of the humerus (upper arm bone). Due to the very loose joint capsule that gives a limited interface of the humerus and scapula, it is the most mobile joint of the human body.

sternoclavicular

The sternoclavicular joint or sternoclavicular articulation is the joint between the sternum and the clavicle. It is structurally classed as a synovial double-plane joint and functionally classed as a diarthrotic joint. It is composed of two portions separated by an articular disc of fibrocartilage. The bone areas entering into its formation are the sternal end of the clavicle, the upper and lateral part of the manubrium sterni (clavicular notch of the manubrium sterni), and the cartilage of the first rib, visible from the outside as the suprasternal notch. The articular surface of the clavicle is much larger than that of the sternum, and is invested with a layer of cartilage, which is considerably thicker than that on the latter bone. The sternoclavicular joint allows movement of the clavicle in three planes, predominantly in the anteroposterior & vertical planes, although some rotation also occurs.A description of movement would be elevation, depression, and circumduction. Muscles don't directly act on this joint, although almost all actions of the shoulder girdle or the scapula will cause some motion at this articulation. The unique double-hinged articular disk found at the junction of the clavicular head and manubrium allows for movement between the clavicle and the disk during elevation and depression of the scapula. This disk also allows motion between the sternum (manubrium) and itself during protraction and retraction of the scapula.

tarsometatarsal

The tarsometatarsal articulations (Lisfranc joint) are arthrodial joints in the foot. The tarsometatarsal articulations involves the first, second and third cuneiform bone, the cuboid bone and the metatarsal bones. The eponym Lisfranc joint is named after 18th-19th century surgeon and gynecologist, Jacques Lisfranc de St. Martin

temporomandibular

The temporomandibular joint is the joint of the jaw and is frequently referred to as TMJ. The TMJ is a bilateral synovial articulation between the mandible and temporal bone. The name of the joint is derived from the two bones which form the joint: the upper temporal bone which is part of the cranium (skull), and the lower jawbone or mandible.

iliofemoral

There are three extracapsular ligaments. They are continuous with the outer surface of the hip joint capsule. Located anteriorly. It originates from the ilium, immediately inferior to the anterior inferior iliac spine.The ligament attaches to the intertrochanteric line in two places, giving the ligament a Y shaped appearance. It prevents hyperextension of the hip joint.
