Question

what is the major function of neurons in neural tissue?
options:
to transmit signals that take the form of changes in the transmembrane potential
to regulate the composition of the interstitial fluid
to act as phagocytes that defend neural tissue
to provide a supporting framework for neural tissue
i dont know yet

Explanation:

Neurons in neural tissue are primarily responsible for transmitting electrical signals (in the form of changes in transmembrane potential, like action potentials) to communicate information. Regulating interstitial fluid is more of a glial cell (e.g., astrocytes) function. Phagocytosing to defend neural tissue is a role of microglia (a type of glial cell), not neurons. Providing a supporting framework is the role of neuroglia (glial cells) like oligodendrocytes, astrocytes, etc. So the correct option is the first one.

Answer:

To transmit signals that take the form of changes in the transmembrane potential
