Multiple Choice

Which statement about white and gray matter is true?

Gray matter is found only in the peripheral nervous system.

White matter is responsible for transmitting signals between different parts of the nervous system.

White matter consists primarily of neuron cell bodies.

Gray matter is composed mainly of myelinated axons.

Verified step by step guidance

Begin by understanding the basic definitions of white and gray matter in the nervous system. Gray matter primarily consists of neuron cell bodies, dendrites, and unmyelinated axons, while white matter is composed mainly of myelinated axons.

Consider the locations of gray and white matter. Gray matter is found in both the central nervous system (CNS) and peripheral nervous system (PNS), not exclusively in the PNS.

Evaluate the functions of white and gray matter. White matter is responsible for transmitting signals between different parts of the nervous system due to its composition of myelinated axons, which facilitate faster signal transmission.

Analyze the statement that gray matter is composed mainly of myelinated axons. This is incorrect because gray matter is primarily made up of neuron cell bodies and unmyelinated axons.

Conclude by identifying the correct statement: White matter is responsible for transmitting signals between different parts of the nervous system, which aligns with its structural composition and function.
