Skeletal System: 206 Human Bones

parietal bone

form the large portion of the roof and sides of the cranium. The sagittal suture, coronal suture, lambdoid suture are tissues that separate the parietals from frontal, occipital, sphenoid, and temporal bones. (2)

zygomatic bone

forms the cheek bones of the face, and articulates with the frontal, sphenoid, temporal and maxilla bones. (2)

vomer bone

forms the posterior aspect of the nasal septum.

calcaneus bone

heel bone is a bone of the tarsus of the foot which constitutes the heel. (2)

intermediate phalange bones

intermediate phalange bones 1-10 is the third bone of the fingers and toes. (10)

patella bone

kneecap, is a thick, circular-triangular bone which articulates with the femur and covers and protects the anterior articular surface of the knee joint. (2)

frontal bone

large bone that makes up the forehead and supplies the upper edge and roof of the orbit (eye socket).

traquetral bone

located in the wrist on the medial side of the proximal row of the carpus between the lunate and pisiform bones. (2)

temporal bone

contributes to the lower lateral walls of the skull. It contains the middle and inner portions of the ear, and is crossed by the majority of the cranial nerves. The lower portion of the bone articulates with the mandible, forming the temporomandibular joint of the jaw. (2)

distal phalange bones

distal phalange bones 1-10 is the fourth and final bone of the fingers and toes. (10)

medial cuneiform bone

first cuneiform, is situated at the medial side of the foot, anterior to the navicular bone and posterior to the base of the first metatarsal. (2)

inferior nasal concha bone

located within the nasal cavity, these bones increase the surface area of the nasal cavity, thus increasing the amount of inspired air that can come into contact with the cavity walls. (2)

metacarpal bones

metacarpal bones 1-10 is the first bone of the fingers and toes. (10)

scaphoid bone

one of the carpal bones of the wrist, is situated between the hand and forearm on the thumb side of the wrist, lateral or radial side. (2)

cuboid bone

one of the several tarsal bones. (2)

ulna bone

prismatic in form and runs parallel to the radius, and is located at the medial side, the side of the little finger. (2)

maxilla bone

comprises part of the upper jaw and hard palate. (2)

incus bone

"anvil shaped" ossicle in the middle ear and receives vibrations from the malleus, to which it is connected laterally, and transmits these to the stapes. (2)

malleus bone

"hammer shaped" ossicle of the middle ear which connects with the incus and is attached to the inner surface of the eardrum. (2)

hamate bone

"hook shaped" irregular carpal bone. (2)

hyoid bone

"horseshoe shaped in the anterior midline of the neck between the chin and the thyroid cartilage and lies at the level of the base of the mandible in the front and the third cervical vertebra (C3) behind.

occipital bone

"saucer shaped" membrane bone situated at the back and lower part of the skull.

navicular bone

"small boat shaped", is one of the tarsal bones, found in the foot, located on the medial side of the foot, and articulates proximally with the talus, distally with the three cuneiform bones, and laterally with the cuboid. (2)

stapes bone

"stirrup shaped" ossicle in the middle of the ear and receives vibrations from the incus, to which it is connected laterally, and transmits these to the oval window. (2)

lateral cuneiform bone

"third cuneiform" and "wedge-shaped", occupies the center of the front row of the tarsal bones, between the intermediate cuneiform medially, the cuboid laterally, the navicular posteriorly and the third metatarsal in front. (2)

sphenoid bone

"wedge like shaped" in the cranium, in the middle of the skull towards the front, in front of the temporal bone and basilar part of the occipital bone, part of the orbit.

intermediate (middle) cuneiform bone

"wedge shaped", is situated between the other two cuneiform bones and articulates with the navicular posteriorly, the second metatarsal anteriorly and with the other cuneiforms on either side. (2)

cervical vertebrae

C1-7.

lumbar vertebrae

L1-5.

thoracic vertebrae

T1-12.

trapezium bone

a carpal bone in the wrist. It forms the radial border of the carpal tunnel. (2)

trapezoid bone

a carpal bone next to the capitate bone. (2)

lunate bone

a carpal bone situated between the lateral scaphoid bone and medial triquetral bone. (2)

humerus bone

a long bone in the arm or forelimb that runs from the shoulder to the elbow. (2)

pisiform bone

a small knobbly, pea-shaped sesamoid bone that is found in the wrist. It forms the ulnar border of the carpal tunnel. (2)

talus bone

ankle bone is a bone in the collection of bones in the foot called the tarsus. (2)

sternum bone

breastbone, a long flat bony plate shaped like a capital "T" located anteriorly to the heart in the center of the thorax (chest). It connects to the rib bones via cartilage, forming the anterior section of the rib cage and helps protect the lungs, heart and major blood vessels from physical trauma.

fibula bone

calf bone is a leg bone located on the lateral side of the tibia, with which it is connected above and below. (2)

clavicle bone

collarbone is a flat bone that serves as a strut between the scapula and the sternum. (2)

proximal phalange bones

proximal phalange bones 1-10 is the second bone of the fingers and toes. (10)

radius bone

radial bone extends from the lateral side of the elbow to the thumb side of the wrist and runs parallel to the ulna. (2)

rib bones

rib 1-12. 11 and 12 are "floating". 2 of each.

ethmoid bone

separates the nasal cavity from the brain and is located at the roof of the nose, between the two orbits and is one of the bones that make up the orbit of the eye.

tibia bone

shinbone or shankbone, the knee with the ankle bones, next to the fibula on the medial side of the leg by the interosseous membrane of leg, forming a type of joint called a syndesmosis with very little movement. (2)

scapula bone

shoulder blade, is the bone that connects the humerus with the clavicle. (2)

palatine bone

situated at the rear of oral cavity, and forms part of the hard palate. (2)

coccyx bone

tailbone.

mandible bone

the jaw bone, articulates with the base of the cranium at the temporomandibular joint (TMJ).

capitate bone

the largest of the carpal bones, occupies the center of the wrist. (2)

lacrimal bone

the smallest bones of the face. They form part of the medial wall of the orbit. (2)

femur bone

thigh bone, the head of the femur articulates with the acetabulum in the pelvic bone forming the hip joint, while the distal part of the femur articulates with the tibia and patella forming the knee joint, is the strongest bone in the body, longest bone in the body. (2)

nasal bone

two slender bones, located at the bridge of the nose. (2)

sacrum bone

upper part of the sacrum connects with the last lumbar vertebra, and its lower part with the coccyx .
