Question

What is found in the periphery of the spinal cord?
A. Grey matter
B. Myelinated nerve
C. White matter
D. Notochord

Answer 1

Hint: The distribution of action potentials are modulated in the periphery of the spinal cord, and communication between different brain regions are controlled.

Complete Answer:
- We know that within the cross-section the peripheral region of the spinal cord contains neuronal white matter which refers to areas of the central nervous system that are mainly made from myelinated axons which also are called as tracts, it’s a passive tissue.
- White matter affects the training and brain functions, modulating the distribution of action potentials which acts as a relay and coordinating communication between different brain regions.
- White matter is named due to its relatively light appearance resulting from the lipid content of myelin. The tissue of the cut brain looks pinkish white to the unaffected eye because myelin has largely lipid tissue veined with capillaries.
- White matter has bundles which are connected to gray matter areas of the brain to every other. These function to hold nerve impulses between neurons.
From the above information, we will conclude that the white matter is found within the periphery of Spinal cord.

Thus, option C is the correct answer.

Note: The spinal cord contains both white matter and grey matter, The brain is an immensely complex structure, but there are ways we can divide up its anatomical structure into more discrete parts; the left and right hemisphere, parietal, temporal, occipital and frontal lobes. Another common divider is to separate the brain’s gray and white matter.
