Cranial nerves are a part of:
Correct answer: A. Brain
- A. Brain
- B. Somatic division
- C. Autonomic division
- D. CNS
Explanation
Cranial nerves originate from the brainstem and extend to various structures in the head, neck, and trunk. While they are anatomically connected to the brain, cranial nerves are not considered part of the brain itself. Instead, they are considered part of the peripheral nervous system (PNS) because they extend from the brain and transmit sensory and motor signals between the brain and peripheral structures.

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.
