Sensory and motor neurons of the nervous system are associated with activities traditionally classified as which of the following?

• A. Somatic nervous system functions
• B. Autonomic nervous system functions
• C. Limbic system functions
• D. Endocrine system functions

Answer: (A)

Verified step by step guidance

1. Step 1: Understand the roles of sensory and motor neurons. Sensory neurons carry information from sensory receptors to the central nervous system, while motor neurons transmit commands from the central nervous system to muscles.
2. Step 2: Recognize that the nervous system is divided into different subsystems, including the somatic nervous system and the autonomic nervous system.
3. Step 3: Identify that the somatic nervous system is responsible for voluntary control of body movements via skeletal muscles, involving sensory input and motor output.
4. Step 4: Contrast this with the autonomic nervous system, which regulates involuntary functions such as heart rate and digestion, and is not primarily associated with sensory and motor neurons controlling voluntary movement.
5. Step 5: Conclude that because sensory and motor neurons are involved in voluntary muscle control and sensory input, they are traditionally classified under somatic nervous system functions.
