Question

exam 3 - chapters 10 and 11 nervous syst
what is found within the gray matter of the spinal cord?
multiple choice
ganglia
myelinated axons
interneurons
cerebrospinal fluid

Explanation:

1. Recall the structure of the spinal cord: Gray matter consists mainly of neuron cell bodies, dendrites, and unmyelinated axons, along with interneurons.
2. Analyze each option:

• Ganglia are collections of neuron cell bodies outside the CNS, not in the spinal cord’s gray matter.
• Myelinated axons are in the white matter (due to myelin sheaths giving the white appearance).
• Cerebrospinal fluid is in the subarachnoid space and central canal, not the gray matter.
• Interneurons (and motor neuron cell bodies, sensory neuron terminals) are found in the gray matter of the spinal cord.

Answer:

B. Interneurons
