What is a Nervous system?

The body's primary communication, controlling, and governing system. The nervous system is in charge of controlling and upholding homeostasis, together with the endocrine system.

What is the Spinal cord?

The spinal cord, which connects the medulla oblongata in the brainstem to the lumbar portion of the vertebral column, is a long, thin, tubular tube consisting of nerve tissue. The cerebrospinal fluid-filled core canal of the spinal cord is enclosed by the backbone. The central nervous system is made up of the brain and spinal cord. In humans, the spinal cord starts at the base of the skull and travels via the foramen magnum before entering the spinal canal at the first cervical vertebra. Between the first and second lumbar vertebrae, the spinal cord comes to a stop.
