MCQ Detailed View

The human body has a framework made up of all its bones, called the skeleton. The skeleton provides structure, support, and shape to the body. It protects internal organs, allows movement by providing attachment points for muscles, and stores important minerals like calcium and phosphorus.

The human skeleton is divided into two main parts:

1. 
   

   Axial skeleton – includes the skull, vertebral column, and rib cage, which protect the brain, spinal cord, and heart/lungs.

   
   


2. 
   

   Appendicular skeleton – includes the limb bones and the girdles (shoulder and pelvic), which help in movement and daily activities.

   
   

Bones are living tissues that grow, repair, and change throughout life. They are connected by joints, which allow motion. The skeleton also produces blood cells in the bone marrow, making it essential for both support and body functions.

Other options in the question are incorrect:

• 
  

  Tissue refers to groups of cells performing a specific function, not the full body frame.

  
  


• 
  

  Skull is just one part of the skeleton and cannot represent the entire framework.

  
  

Understanding the skeleton is a key topic in biology, especially in human anatomy and physiology. It helps students learn how bones, joints, and muscles work together to maintain posture, protect organs, and enable movement.

In short, all the bones of the body together form the skeleton, which is the body’s complete framework and provides structure, protection, and mobility.
