Which term describes the division of the peripheral nervous system that controls involuntary motor functions?
Correct Answer:
Autonomic Nervous System
Explanation:
The part of the peripheral nervous system that governs involuntary motor functions is the autonomic nervous system. It controls automatic activities like heart rate, digestion, respiratory rate, pupillary changes, and glandular secretion, keeping the body in balance without conscious effort. It operates through two main branches: the sympathetic system, which prepares the body for action, and the parasympathetic system, which promotes rest and digestion. The other terms don’t describe a nervous-system division: an arteriole is a blood vessel, automaticity refers to spontaneous impulse generation, and the calcaneus is a heel bone.
