Question at position 16 What is the long fiber that conducts messages from a neuron to other cells?HypothalamusGliaDendriteAxon

BlackTom AI · Accepted Answer

In this question, we are being asked to identify the long fiber that conducts messages from a neuron to other cells.
Option 1: Hypothalamus. This is a specific brain region, not a fiber structure of a neuron, so it does not function as the conducting fiber that transmits neural impulses.
Option 2: Glia. Glial cells support neurons structurally and metabolically but are not the long fibers that carry electrical messages along their length.
Option 3: Dendrite. Dendrites receive signals from other neurons or receptors, not the long conducting fiber that sends messages away from the neuron body.
Option 4: Axon. The axon is the elongated projection of a neuron that transmits electrical impulses away from the cell body toward other neurons, muscles, or glands, functioning as the primary conducting fiber.
Thus, among the choices, the axon best fits the description of the long fiber that conducts messages from a neuron to other cells.
