axons ____.

b) carry out the metabolic functions of a neuron
a) are branched fibers that are the primary receivers of impulses from other neurons
c) are the slender tail - like extension at the transmitting end of a neuron that is involved in sending impulses to other neurons
d) are the fatty substance that insulates neural connections

Explanation:

To solve this, we analyze each option:

• Option B: Metabolic functions of a neuron are mainly carried out by the cell body (soma), not axons. Eliminate B.
• Option A: Dendrites are the branched fibers that receive impulses from other neurons, not axons. Eliminate A.
• Option C: Axons are slender, tail - like extensions at the transmitting end of a neuron, and their main function is to send electrical impulses (action potentials) to other neurons (either to other neurons, muscles, or glands). This matches the definition of an axon.
• Option D: The fatty substance that insulates neural connections (axons, in most cases) is myelin (produced by oligodendrocytes in the CNS and Schwann cells in the PNS), not the axon itself. Eliminate D.

Answer:

C) are the slender tail - like extension at the transmitting end of a neuron that is involved in sending impulses to other neurons
