The axial skeleton and appendicular skeleton quiz offers an in-depth exploration of the intricate structures and functions of these skeletal components. This quiz delves into the anatomy, physiology, and clinical significance of the axial and appendicular skeletons, providing a comprehensive understanding of their roles in human movement, protection, and overall health.

The axial skeleton, composed of the skull, vertebral column, and rib cage, forms the central axis of the body. It provides structural support, protects vital organs, and facilitates movement. The appendicular skeleton, consisting of the limbs and their associated bones, enables locomotion, manipulation of objects, and weight-bearing.

Axial Skeleton

The axial skeleton is the central and vertical part of the skeleton that forms the body’s axis and supports the head, neck, and trunk.

Structure

The axial skeleton consists of 80 bones and is divided into four regions:

• Skull (22 bones)
• Vertebral column (26 bones)
• Rib cage (25 bones)
• Sternum (1 bone)

Functions, Axial skeleton and appendicular skeleton quiz

• Supports and protects vital organs
• Provides attachment points for muscles
• Facilitates movement
• Stores and produces blood cells

Appendicular Skeleton



The appendicular skeleton consists of 126 bones that form the limbs, girdles, and bones of the hands and feet.

Structure

• Upper limb (60 bones): arms, forearms, hands, and fingers
• Lower limb (66 bones): thighs, legs, feet, and toes

Functions, Axial skeleton and appendicular skeleton quiz

• Supports the weight of the body
• Facilitates locomotion
• Provides attachment points for muscles
• Protects vital organs
