Overview
Made up of the bones in your head, neck, back and chest, your axial skeleton supports and cushions your brain, spinal cord and organs in your body.
Function
Your axial skeleton provides support and cushioning for your brain, spinal cord and organs in your body. Muscles in your body that move your head, neck and trunk attach to your axial skeleton. These muscles help you breathe and steady parts of your appendicular skeleton.
Conditions and Disorders
Many conditions can cause problems with your axial skeleton. Some develop due to wear and tear as you age. Others happen as a result of disease or injury. Conditions that may affect your axial skeleton include:
Care
The best way to take care of your axial skeleton is to maintain a healthy lifestyle. To keep your bones strong and healthy:

What are the components of the axial skeleton?
Axial Skeleton Components. The main components of axial skeleton are: The Skull. The Vertebral Column. Thoracic Cage. Fig: Axial Skeleton Components. 1. Skull: The skull is a bony framework of the head that protects the brain. It acts as a cover to the brain and supports the structure of the face.
What are the bones of the limbs attached to the axial skeleton?
The skull, the vertebral column, sternum, and ribs constitute the axial skeleton.” (Source: NCERT). Definition: The bones of the limbs are attached to the axial skeleton via girdles. The axial skeleton forms the main frame of the body in the longitudinal axis.
How many bones are in the appendicular skeleton?
It consists of 80 bones that include the skull, vertebral column, and thoracic cage. The appendicular skeleton consists of 126 bones and includes all bones of the pectoral girdle, the upper limbs, the pelvic girdle, and the lower limbs. Q.2.
What are the two parts of the skeletal system?
The skeletal system of humans can be basically divided into two parts (i) the axial skeleton and (ii) the appendicular skeleton. The axial skeleton constructs the central axis of the body, while the appendicular skeleton comprises the limbs and girdles.
