Verified step by step guidance1
Understand the structure of the cerebral cortex: The cerebral cortex is the outer layer of the brain, involved in many complex brain functions such as perception, thought, and decision-making.
Differentiate between gray matter and white matter: Gray matter primarily consists of neuron cell bodies, dendrites, and unmyelinated axons, while white matter is mainly composed of myelinated axons.
Identify the components of gray matter: Gray matter is rich in neuron cell bodies, which are crucial for processing information in the brain.
Consider the options provided: Evaluate each option to determine which one is most closely associated with the composition of gray matter.
Conclude that the gray matter of the cerebral cortex is composed mostly of neuron cell bodies, as they are the primary components involved in higher-level brain functions.
