What best describes the somatic nervous system?

The somatic nervous system is best described as the system that connects the central nervous system (CNS) to skeletal muscles. This system is responsible for voluntary movements, allowing individuals to control their actions and perform tasks that require muscle coordination. These connections enable the brain to send signals for movement, allowing for precise control over bodily actions such as walking, writing, or playing sports.

In contrast, other systems mentioned focus on different aspects of nervous system function. For instance, involuntary muscle movements pertain to the autonomic nervous system, which manages bodily functions not under conscious control, and internal organ regulation is also a function of the autonomic system. Reflexive responses, while they can involve the somatic system, are primarily automatic and fast, indicating more of a role for spinal cord pathways rather than direct control by the somatic system itself. Therefore, the description linking the somatic nervous system to the CNS and skeletal muscles accurately captures its primary function.
