Question

Quizplus · Accepted Answer

The brain and the spinal cord are connected and form the central nervous system, which is a continuous unit of tissue responsible for integrating and processing information in the body.

Answer: B
 The brain and the spinal cord consist of both white and gray matter. Gray matter is made up of neuron cell bodies and white matter is made up of myelinated axons that connect different parts of the brain and spinal cord.

Answer: C
 Although there is some potential for neural connections to regenerate or reorganize after injury, the brain and spinal cord generally have limited ability to heal damaged tissue or restore lost function.

Answer: D
 The brain and spinal cord are part of the central nervous system, which is distinct from the peripheral nervous system. The peripheral nervous system consists of nerves and ganglia that connect the central nervous system to the rest of the body, and it includes both sensory and motor neurons.
