Axial skeleton function
The axial skeleton is the central axis of the human body and is composed of 80 bones that play a crucial role in protecting and supporting the body's organs and tissues.
The axial skeleton is divided into two main regions: the skull and the vertebral column. The skull, made up of 22 bones, protects the brain and provides attachment points for muscles that control head movement. The vertebral column, made up of 26 bones, forms the backbone and supports the body's weight. It also protects the spinal cord, which carries nerve impulses between the brain and the rest of the body.
One of the primary functions of the axial skeleton is to provide support for the body. The skull and vertebral column work together to support the body in an upright position, allowing us to stand, walk, and move freely. The bones of the skull also provide a stable foundation for the muscles of the face and head, allowing us to make facial expressions and communicate through speech.
In addition to providing support, the axial skeleton also plays a vital role in protecting the body's organs and tissues. The skull protects the brain, the most important organ in the body, and the vertebral column protects the spinal cord, which is essential for the proper functioning of the body's nervous system.
The axial skeleton also serves as a point of attachment for muscles, allowing us to move and perform various physical activities. The bones of the skull and vertebral column provide attachment points for the muscles that control head and neck movement, as well as those that support and move the upper and lower limbs.
Overall, the axial skeleton is an essential part of the human body, providing support, protection, and a point of attachment for muscles. Its many functions are vital to our ability to move and function properly in daily life.
