Question

What does the central canal of the spinal cord contain?

Answer 1

Hint: The brain and spinal cord comprise the central nervous system (CNS). The cerebrospinal fluid is found in the space between the arachnoid space and the pia mater (CSF). The dura mater, arachnoid mater, and pia mater are the three layers of meninges that protect the spinal cord.

Complete answer:
The spinal cord is a long, thin, tubular structure made of nervous tissue that extends from the brainstem's medulla oblongata to the lumbar region of the vertebral column. It protects the spinal cord's central canal, which contains cerebrospinal fluid. The central nervous system is made up of the brain and spinal cord (CNS).

In humans, the spinal cord starts at the occipital bone and travels through the foramen magnum before entering the spinal canal at the first cervical vertebrae. The spinal cord extends down to the first and second lumbar vertebrae, where it terminates. The bony vertebral column that surrounds the spinal cord protects the relatively short spinal cord.

Cerebrospinal fluid is found in the spinal cord's central canal. The pleural fluid surrounds the lungs, interstitial fluid surrounds multicellular animals' cells, and aqueous humour is the fluid that exists between the lens and the cornea of the eye.

Thus, the central canal of the spinal cord contains cerebrospinal fluid.

Note: One significant issue with rabies prevention is a lack of basic life-saving knowledge among those at risk. Organizations working on the issue can often feel isolated, and rabies, as a neglected disease, does not attract sufficient resources, even though the world has the tools and knowledge to prevent rabies and that no one should die from it.
