Multiple Choice

Which of the following best describes the primary function of the spinal cord within the central nervous system?

It produces cerebrospinal fluid for the brain.

It regulates hormone secretion from endocrine glands.

Verified step by step guidance

Step 1: Understand the role of the spinal cord within the central nervous system (CNS). The spinal cord is a cylindrical structure made of nervous tissue that extends from the brainstem down the vertebral column. Its primary function is to act as a communication highway between the brain and the rest of the body.

Step 2: Eliminate incorrect options by analyzing their relevance to the spinal cord's function. For example, the spinal cord does not produce cerebrospinal fluid; this is primarily the role of the choroid plexus in the brain's ventricles.

Step 3: Consider the option about hormone secretion. Hormone regulation is primarily controlled by the endocrine system, including glands like the hypothalamus, pituitary, and adrenal glands, not the spinal cord.

Step 4: Evaluate the option about conscious thought and memory storage. These functions are associated with the brain, particularly the cerebral cortex, not the spinal cord.

Step 5: Confirm the correct answer: The spinal cord's primary function is to transmit sensory and motor information between the brain and the rest of the body, enabling communication and coordination of bodily functions.
