Answer:
Human skeleton system has two major components namely axial and appendicular . The major difference between axial and appendicular skeleton is that the axial has 80 bones located along the axis of the body while the appendicular has 126 bones of appendages and girdles that are connected to the axial skeleton.
The axial skeleton refers to the bones of the head, neck, and trunk of the body. It includes the skull, vertebral column, ribcage, and sternum. The axial skeleton provides support for the head and trunk, as well as protection for the brain, spinal cord, and organs in the thorax and abdomen. It also allows for movement of the head and neck, as well as the ability to bend and twist the torso.
The appendicular skeleton refers to the bones of the limbs, including the shoulders, hips, and limbs themselves. It includes the clavicles, scapulae, humeri, radius, ulna, pelvis, femur, tibia, fibula, and bones of the hands and feet. The appendicular skeleton allows for movement of the limbs, such as walking, running, and reaching, as well as providing support for the body when standing or sitting.
In summary, the axial skeleton is the part of the skeleton that provides support and protection for the head, neck, and trunk, while the appendicular skeleton is the part of the skeleton that provides movement and support for the limbs.
