Identify the statement that best differentiates gray matter and white matter.
A) Gray matter consists of cell bodies and dendrites, whereas white matter consists mostly of myelinated axons.
B) Gray matter consists of all parts of neurons, and white matter is mostly glial cells.
C) Gray matter consists of bundles of axons, and white matter consists of groups of cell bodies and dendrites.
Gray Matter
Brain tissue comprising neuron cell bodies, dendrites, and unmyelinated axons, involved in muscle control and sensory perception.
White Matter
Tissue in the brain and spinal cord made up of nerve fibers, which is responsible for transmitting signals between different areas of the central nervous system.
Myelinated Axons
Axons that are covered by a fatty sheath called myelin, which increases the speed of electrical impulses along nerve cells.

Final Answer :
A
Explanation :
Gray matter is primarily made up of neuron cell bodies and dendrites, which are involved in processing and integration of information in the brain and spinal cord. White matter, on the other hand, is composed largely of myelinated axons, which are responsible for the transmission of nerve impulses between different parts of the nervous system.
