Final answer:
The efferent branch of the peripheral nervous system consists of the somatic motor and autonomic divisions, with the latter comprising the sympathetic and parasympathetic divisions, which have opposing effects on the body. so, option 3 is the correct answer.
Step-by-step explanation:
The efferent branch of the peripheral nervous system is composed of the somatic motor and autonomic divisions. The somatic nervous system is responsible for voluntary movements, such as muscle contractions, while the autonomic nervous system controls involuntary functions, such as heart rate and digestion. Within the autonomic nervous system, there are two critical divisions: the sympathetic and parasympathetic nervous systems. The sympathetic nervous system prepares the body for a 'fight-or-flight' response during stressful situations, and the parasympathetic nervous system is active during restful periods to help conserve energy and maintain normal bodily functions.
The efferent branch of the peripheral nervous system is composed of the somatic motor and autonomic divisions. The somatic motor division controls voluntary movements of skeletal muscles, while the autonomic division controls involuntary functions.
