A nerve to the heat would be classified as a part of:
Correct answer: B. A ganglion
- A. Spinal cord
- B. A ganglion
- C. Non-nervous auxiliary system
- D. Somatic division of the peripheral nervous system
Explanation
The somatic division of the peripheral nervous system (PNS) controls voluntary movements and sensory perception. It includes nerves that innervate skeletal muscles and carry sensory information from the skin, muscles, and joints to the central nervous system (CNS). A nerve responsible for sensing heat would fall under the somatic division if it is transmitting sensory information from the skin to the CNS.

About Coordination and Control
Coordination depends on receptors, neurons, synapses and nerve impulses, with reflex actions traced through the reflex arc and the roles of major brain regions. Chemical coordination covers endocrine glands and hormones, including how hormones regulate growth, metabolism, reproduction and internal balance, unlike rapid nervous control.
