responding to neural tissue damage.
a. Neurons play a role in all of these functions.
b. Microglia do not conduct action potentials.
c. Schwann cells respond to neural tissue damage.
d. Astrocytes guide neuron development.

Answer 1

Neurons perform multiple functions, including guiding neuron development, maintaining the blood-brain barrier, and conducting action potentials. Astrocytes, not neurons, form a three-dimensional framework for the CNS. So, the correct answer is option d.

Step-by-step explanation:

Neurons perform all of the mentioned functions in the question, with the exception of forming a three-dimensional framework for the central nervous system (CNS). While neurons guide neuron development, maintain the blood-brain barrier, and conduct action potentials, it is astrocytes that form a three-dimensional framework for the CNS.

Astrocytes also guide neuron development, while microglia do not conduct action potentials and Schwann cells respond to neural tissue damage.

So, the correct answer is option d.
