Question

What is the main function of motor neurons?

(A) To carry signals from the central nervous system (CNS) to effector cells
(B) To receive signals from sensory neurons and transmit them to the CNS
(C) To integrate signals from multiple neurons and generate a response
(D) To store and process information

Answer 1

Motor neurons carry signals from the central nervous system to effector cells like muscles and glands, initiating actions such as muscle contractions or gland secretions.

Step-by-step explanation:

The main function of motor neurons is (A) To carry signals from the central nervous system (CNS) to effector cells. Motor neurons transmit nerve impulses from the CNS to various effector organs such as muscles and glands.

When the central nervous system decides on a response to sensory information, motor neurons are responsible for conveying the instructions to the muscles and glands to cause a reaction, whether it be muscle contraction or gland secretion. These neurons play an essential role in the initiation of voluntary and reflex movements essential for an organism's interaction with its environment.
