What is the primary function of a motor neuron?

• A. To transmit sensory information to the brain
• B. To take the impulse to the effector organ
• C. To connect sensory neurons with motor neurons
• D. To maintain homeostasis in the body

Answer: (B)

The primary function of a motor neuron is to take the impulse to the effector organ. Motor neurons are a crucial component of the nervous system, as they are responsible for transmitting signals from the central nervous system (CNS) to effectors, which can be muscles or glands. When a motor neuron is activated, it sends an electrical impulse that leads to a specific action, such as muscle contraction or gland secretion. This role is essential for carrying out voluntary movements and reflex actions, allowing an organism to respond to stimuli effectively. In the context of various biological systems, understanding the pathways for these impulses is vital for appreciating how movement and physiological responses are coordinated in the body.
