What is Meant by Axial?
Axial, as the name suggests, means part(bones) of the body which forms the central axis of the body. This can include the main structural elements of the body, such as the bones that form the central axis of the body in humans and most vertebrates.
The axial system in humans is composed of the skull, vertebral column, and rib cage. The skull forms the uppermost part of the axial system and protects the brain, while the vertebral column runs from the skull to the pelvis, providing support and protection to the spinal cord. The rib cage surrounds and protects the thoracic organs, such as the heart and lungs.
The axial system is essential for the overall structure and function of the body, as it provides support and protection to vital organs, allows for movement and coordination, and houses the central nervous system. It also plays a role in the regulation of breathing, circulation, and digestion.
Difference Between Axial and Appendicular
Axial and appendicular skeletons are the two main divisions of the human skeletal system. The axial skeleton includes bones from the central axis of the body, while the appendicular skeleton includes bones of the limbs and the girdles (shoulder and pelvic) that attach them to the axial skeleton.
The axial skeleton includes the skull, vertebral column, and ribcage. These bones protect the vital organs in the head and torso and provide support and structure for the body. The appendicular skeleton includes the bones of the arms, legs, hands, and feet. These bones are involved in movement and locomotion and also play a role in manipulating the environment.
