NERVE CANAL Meaning and
Definition
-
A nerve canal refers to a cylindrical or tube-like structure that serves as a protective passageway for nerves to travel through. It can be found within bones, particularly in the skull and spinal column, acting as a pathway for nerves to transmit signals between the brain and the rest of the body. A nerve canal is specifically designed to shield and support delicate nerve fibers from potential damage and compression, ensuring the proper functioning of the nervous system.
The nerve canal is typically lined with a specialized tissue called endosteum, which provides nourishment and protection to the nerves passing through it. It is often encased within the hard, mineralized tissues of bones, such as cortical bone or compact bone. In the skull, the nerve canals are known as cranial foramina, and each foramen corresponds to a different cranial nerve.
The size and shape of nerve canals can vary depending on the specific bone and its function. For example, the spinal canal within the vertebral column provides ample space for the spinal cord to pass through, while the optic canals in the skull accommodate the optic nerves, responsible for vision.
In summary, a nerve canal refers to a protective passageway within the skeletal system that allows nerves to travel safely, ensuring the communication between the central nervous system and peripheral nerves remains uninterrupted.

Etymology of NERVE CANAL
