Final answer:
Motor neurons, which carry impulses from the central nervous system to muscles and glands, are also known as efferent neurons and are part of the somatic nervous system.
Step-by-step explanation:
Another name for motor neurons is efferent neurons. These types of neurons are crucial in the nervous system as they carry nerve impulses from the central nervous system to the body's muscles and glands.
They convert the nerve signals into activation responses, triggering movement or secretion in these peripheral structures. Motor neurons fall under the category of the somatic nervous system, meaning they are associated with voluntary control. This is unlike sensory neurons, which are termed afferent neurons because they carry information towards the central nervous system. Motor neurons enable the conscious control of muscle movements, which is essential for all voluntary actions.
