The Amazing World of the Skeletal System

What are the two broad divisions of the skeletal system?

a) Appendicular skeleton b) Peripheral skeleton c) Vertebral skeleton d) Radial skeleton

Final Answer:

The skeletal system consists of two main divisions: the axial and appendicular skeleton. The correct option is A.

The skeletal system is an incredibly fascinating part of our body that plays a crucial role in providing support, protection, and movement. It is divided into two broad divisions: the axial skeleton and the appendicular skeleton.

The axial skeleton includes all bones from the head, neck, chest, and back. These bones form the central axis of the body and provide protection for vital organs such as the brain, spinal cord, heart, and lungs. Additionally, the axial skeleton serves as attachment points for muscles that allow us to move our head, neck, and back, as well as muscles that facilitate movement across shoulder and hip joints.

On the other hand, the appendicular skeleton consists of all bones of the upper and lower limbs, along with the bones that connect each limb to the axial skeleton through the pectoral and pelvic girdles. This part of the skeletal system includes the bones of our arms, legs, hands, feet, shoulders, and pelvic bones that enable us to move and perform various activities.

Understanding the structure and function of the skeletal system is essential for maintaining a healthy and active lifestyle. By learning about these two main divisions of the skeletal system, we can appreciate the incredible complexity and versatility of our bodies.
