In nervous tissue, what is the primary function of a neuron?

• A. To provide structural support by synthesizing and storing extracellular matrix fibers in nervous tissue
• B. To receive, process, and transmit electrical signals (nerve impulses) to other cells
• C. To secrete hormones directly into the bloodstream to regulate distant target organs
• D. To produce myelin by wrapping around axons in the central nervous system

Answer: (B)

Verified step by step guidance

1. Step 1: Understand the role of neurons in nervous tissue. Neurons are specialized cells responsible for communication within the nervous system.
2. Step 2: Recognize that neurons transmit information through electrical signals called nerve impulses, which allow them to communicate with other neurons, muscles, or glands.
3. Step 3: Differentiate neurons from other cell types in nervous tissue, such as glial cells, which provide support and protection but do not transmit electrical signals.
4. Step 4: Identify that the primary function of a neuron is to receive signals through dendrites, process these signals in the cell body, and transmit them along the axon to other cells.
5. Step 5: Conclude that the main function of neurons is to receive, process, and transmit electrical signals (nerve impulses), which is essential for nervous system communication and coordination.
