How many bones in the body?

Question

How many bones are in adult and a child? In the adult, what are their names, location, functions and groups?

Answer 1

The total number of bones varies at different ages. At birth, the human body contains ~270 bones. This number declines slightly during infancy as a few separate segments join to form single bones. From young childhood through puberty, the bone count increases as wrist and ankle bones develop. Post-adolescence, the bone count steadily declines again with the gradual union of independent bones.

The adult skeleton consists of 206 bones: 28 skull bones (8 cranial, 14 facial, and 6 ear ossicles); the horseshoe-shaped hyoid bone of the neck; 26 vertebrae (7 cervical or neck, 12 thorax, 5 lumbar or loins, the sacrum which is five fused vertebrae, and the coccyx, our vestigial tail, which is four fused vertebrae); 24 ribs plus the sternum or breastbone; the shoulder girdle (2 clavicles, the most frequently fractured bone in the body, and 2 scapulae); the pelvic girdle (2 fused bones); and 30 bones in each of the four extremities (a total of 120). The paired bones include the 12 ribs on either side, 8 wrist bones, 5 hand bones, 14 finger bones, 7 ankle bones, 5 foot bones, 14 toe bones, 3 auditory ossicles, and the parietal, temporal, palatine, lacrimal, nasal, upper jaw, cheek, lower nasal concha, collarbone, shoulder blade, hip, arm, outer and inner forearm, thigh, kneecap, calf, and shin bones. There are also a variable number of sesamoid bones, ranging from 8-18 in number, which are small rounded masses embedded in certain tendons and usually related to joints.

Hope this helps.

Answer 2

At birth the human body has about 350 bones, but by the time adulthood rolls around, some of our bones have fused together to give us a total of 206 bones in our body!

Here is the breakdown:

The adult skeleton consists of 206 bones . . .

- 28 skull bones (8 cranial, 14 facial, and 6 ear bones);

- the horseshoe-shaped hyoid bone of the neck; Basically, there are 7 vertebrae and the hyoid bone in the neck.

- 26 vertebrae (7 cervical or neck, 12 thorax, 5 lumbar or loins, the sacrum which is five fused vertebrae, and the coccyx, our vestigial tail, which is four fused vertebrae);

- 24 ribs plus the sternum or breastbone; the shoulder girdle (2 clavicles, the most frequently fractured bone in the body, and 2 scapulae);

- the pelvic girdle (2 fused bones);

- 30 bones in our arms and legs (a total of 120);

- There are also a few partial bones, ranging from 8-18 in number, which are related to joints.
