At birth the human body has over 300 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!
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.

A typical adult human skeleton consists of the following 206-350 bones depending on age, though this number does vary owing to a variety of anatomical variations; for example, a small portion of the human population have an extra rib, or an extra lumbar vertebra.

The average adult has 8 cranial, 14 facial, 26 vertebrae, 24 ribs, the scapula, 6 in the ear, the hyoid, 64 in the upper girdle (shoulders, arms and hands), and 62 in the lower girdle (pelvis, legs and feet). That makes a total of 206 bones.

not conflicting.206 unless you have a sesamoid that will turn into a bone. we have over 300 however, they fuse together to make 206. unless you develop calcified tissue that turns to sesamoid a bone. however, correct answer is 206. thank you.

When we are fully grown its 206. When we are born we have about 300. As we grow many bones fuse together.
FYI: Women do not have an extra rib.

206 bones when you are an adult. 300 something when you are just born. the bones fuse as you get older.
