Verified step by step guidance

Step 1: Begin by understanding the somatic nervous system (SNS). The SNS is a part of the peripheral nervous system responsible for voluntary control of body movements via skeletal muscles.

Step 2: Recall that the somatic nervous system connects the central nervous system (CNS), which includes the brain and spinal cord, to the skeletal muscles. This connection allows for conscious control of movement.

Step 3: Eliminate incorrect options by considering the function of the SNS. The SNS does not regulate endocrine glands, blood vessels, lungs, digestive organs, heart, or smooth muscles, as these are typically controlled by the autonomic nervous system.

Step 4: Focus on the correct pairing: the central nervous system and skeletal muscles. This connection enables voluntary motor control, such as walking or lifting objects.

Step 5: Confirm your understanding by reviewing the role of motor neurons in the somatic nervous system. Motor neurons transmit signals from the CNS to skeletal muscles, facilitating movement.
