Answer
The division of the skeleton into the axial and appendicular parts is based on the functional and anatomical roles of the bones. The axial skeleton is primarily involved in support and protection, while the appendicular skeleton is involved in movement and locomotion.
Work Step by Step
The skeleton is divided into two major divisions: the axial skeleton and the appendicular skeleton.
The axial skeleton includes the bones that form the central axis of the body, including the skull, vertebral column, ribs, and sternum. These bones provide support and protection for the internal organs of the body, as well as attachment sites for muscles that support the head, neck, and trunk.
The appendicular skeleton includes the bones of the limbs (arms and legs) and their associated girdles (shoulder and hip). These bones are involved in movement and locomotion, and provide attachment sites for the muscles that move the limbs and stabilize the joints.
