Joints
Bones that make up pelvis
s formed posteriorly (in the area of the back), by the sacrum and the coccyx and laterally and anteriorly (forward and to the sides), by a pair of hip bones. Each hip bone consists of 3 sections, ilium, ischium, and pubis.
Joints and muscles
All muscles cross the joints. If they do not cross a joint, it means they will not be able to move our body parts. If any muscle starts at the elbow and ends up near the wrist then the hand becomes totally solid enough that it cannot be moved properly. The muscles that are connected to the joint bones are called tendons. The main function of the muscle is to move our body parts. The human skeleton cannot be moved without the help of muscles. Without the muscle help, our body cannot be moved from one place to the other, our eyes may not blink, the food may not be digested, we may not breathe, the heart pumping may not occur, we may not smile, urination and defecation may not be possible and our nose may not be used for smelling.
Amphiarthrotic
An example is the manubriosternal joint or the joints between the skull bones surrounding the brain. An amphiarthrosis is a slightly moveable joint, such as the pubic symphysis or an intervertebral cartilaginous joint. A diarthrosis is a freely moveable joint.
Malleoli bones
Each leg is supported by two bones, the tibia on the inner side (medial) of the leg and the fibula on the outer side (lateral) of the leg. The medial malleolus is the prominence on the inner side of the ankle, formed by the lower end of the tibia.
Bones that make up coxal joint
Hip Anatomy, Function and Common Problems. A joint forms where two or more bones meet. The hip joint is a ball-and-socket type joint and is formed where the thigh bone (femur) meets the three bones that make up the pelvis: the ilium at the rear, the ischium at the lower front and the pubis above it.
Diarthrotic
Most synarthrosis joints are fibrous joints (e.g., skull sutures). amphiarthrosis - permits slight mobility. Most amphiarthrosis joints are cartilaginous joints (e.g., intervertebral discs). synovial joint (also known as a diarthrosis) - freely movable
Synarthrotic
Synchondroses are cartilaginous joint connected by hyaline cartilage, as seen in the epiphyseal plate. Sutures are fibrous joints made of a thin layer of dense fibrous connective tissue that unites skull bones.
Ball and socket joint
The ball and socket joint (or spheroidal joint) is a type of synovial joint in which the ball-shaped surface of one rounded bone fits into the cup-like depression of another bone.
Facet joint
The facet joints are the joints in your spine that make your back flexible and enable you to bend and twist. Nerves exit your spinal cord through these joints on their way to other parts of your body. Healthy facet joints have cartilage, which allows your vertebrae to move smoothly against each other without grinding.
Bones that make up glenohumeral joint
The human shoulder is made up of three bones: the clavicle (collarbone), the scapula (shoulder blade), and the humerus (upper arm bone) as well as associated muscles, ligaments and tendons. The articulations between the bones of the shoulder make up the shoulder joints.
Bones that make up patellofemoral joint
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.
6 types of joints
The six types of synovial joints are the pivot, hinge, saddle, plane, condyloid, and ball-and-socket joints. A joint's structure determines its function
Gliding joint
a freely moving joint in which the articulations allow only gliding motions
Ellipsoidal/condyle joint
a synovial joint in which a condyle is received into an elliptic cavity, as the wrist joint. A condyloid joint permits no axial rotation but allows flexion, extension, adduction, abduction, and circumduction.
Hinge joint
A joint, such as the elbow, in which a convex part of one bone fits into a concave part of another, allowing motion in only one plane.
Pivot joint
A joint in which a section of a cylinder of one bone fits into a corresponding cavity on the other, permitting rotating movement, as in the proximal articulation between the radius and ulna. Also called rotary joint, trochoid joint.
