Answer :
Answer:
126 bones in humans.
Explanation:
Firstly we should define what the appendicular skeleton constitutes, it is the part of the skeleton that makes up the "appendages" that is the limbs.
There are four limbs in the human body 2 forelimbs and 2 hindlimbs, the forelimbs are connected to the axial skeleton (the sternum) by the pectoral girdle which constitutes 2 scapulae and 2 clavicles, the hindlimbs are articulated with the axial skeleton (the sacrum of the vertebral column) by a pelvic girdle consisting of 2 pubic bones (os pubis). Each of the limbs constitutes 30 bones (1 humerus (arm) 1 radius, 1 ulna (forearm), 8 carpals (wrist)/ 7 tarsals (ankle), 5 meta carpals (palm)/tarsals (foot), and 14 phalanges (fingers/toes), there is 1 patella over the knee joint in hindlimb).
Therefore, the total becomes 30*4+4+2=126
Final answer:
The appendicular skeleton consists of 126 bones, including the bones of the limbs, shoulder girdle, and pelvic girdle.
The correct answer is option B) 126.
Explanation:
The appendicular skeleton consists of a total of 126 bones. It includes the bones of the four limbs, shoulder girdle, and pelvic girdle. The girdles attach the appendages to the axial skeleton.
