Question

Which of the following is an example of an appendicular bone? Mark all that apply to get this question correct.

A) Bones of skull
B) Bones of vertebral column
C) Ribs
D)Bones of fore and hind limb

Answer 1

The appendicular skeleton consists of the bones in the limbs and their girdles, specifically including the bones of the fore and hind limbs. Bones of the skull, vertebral column, and ribs are not part of the appendicular skeleton.

Step-by-step explanation:

The appendicular skeleton is responsible for our ability to move and includes all the bones of the upper and lower limbs, as well as those that attach the limbs to the axial skeleton. Specifically, the appendicular skeleton is composed of the bones of the pectoral limbs (i.e., arm, forearm, hand), the pelvic limbs (i.e., thigh, leg, foot), the pectoral girdle, and the pelvic girdle. Therefore, when identifying an appendicular bone, the correct answer would be the bones of the fore and hind limb. The bones of the skull, vertebral column, and ribs are all part of the axial skeleton and not the appendicular skeleton. The appendicular skeleton facilitates locomotion and various movements, distinguishing it from the axial skeleton which mainly provides support and protection for the brain, spinal cord, and thoracic organs.
