Functionally _ pairs of cranial nerves are sensory in nature and _ pairs are mixed in nature and _ are motor in nature
Correct answer: A. 3,4 and 5
- A. 3,4 and 5
- B. 4,5 and 3
- C. 3,5 and 4
- D. 4,3 and 5
Explanation
The 12 pairs of cranial nerves are divided based on their functionality: 3 pairs are sensory in nature (olfactory, optic, and vestibulocochlear), 4 pairs are mixed (trigeminal, facial, glossopharyngeal, and vagus), and 5 pairs are motor (oculomotor, trochlear, abducens, accessory, and hypoglossal). Understanding these classifications can help in correctly identifying their functions and roles in the nervous system. The correct option, 3, 4, and 5, reflects this accurate distribution.

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.
