Practice Question
Which of the following is an efferent neuron that is responsible for releasing a neurotransmitter that stimulates a muscle cell to contract?
Answer Choices:
Correct Answer:
Motor neuron
Rationale:
▶ A motor neuron is an efferent neuron, meaning it carries signals away from the central nervous system to effector organs, such as muscles and glands.
▶ When stimulated, a motor neuron releases neurotransmitters (commonly acetylcholine) at the neuromuscular junction, which triggers muscle contraction.
▶ This process is essential for all voluntary and reflexive movements, making motor neurons key players in the somatic nervous system.
