Question

23. Which of the following does NOT pertain to neurons?

Answer 1

Neurons do not facilitate immune responses to foreign antigens.

Step-by-step explanation:

The answer to the question “Which of the following does NOT pertain to neurons?” is: b. facilitate immune response to foreign antigens. Neurons are specialized cells in the nervous system that are responsible for sending electrical and chemical signals. They have various morphological adaptations that make them suitable for the transmission of nerve impulses, such as dendrites and axons. However, neurons are not involved in facilitating immune responses to foreign antigens.

Answer 2

The false statement is that the myelin sheath provides insulation to dendrites; it actually insulates axons.

Step-by-step explanation:

The statement that does NOT pertain to neurons is that the myelin sheath provides an insulating layer to the dendrites. In actuality, the myelin sheath insulates axons, not dendrites. The soma is indeed the cell body of a neuron, axons are responsible for carrying signals away from the soma, and dendrites carry the signals towards the soma. Therefore, the correct answer is that it is false to say the myelin sheath insulates dendrites.

The myelin sheath is a fatty layer that wraps around axons, which helps to increase the speed of signal transmission.

On the other hand, dendrites receive signals from other neurons and transmit them to the cell body (soma). They do not have a myelin sheath.
