Hint: Cranial nervous systems are typically classified either as sensory or as motor. Sensory nerves include the senses, including smell, listening and touch.
The motor nerves regulate muscle or gland movement and function.
Complete answer: Cranial nerves are nerve pairs that link the brain to various parts of the head, spine, and trunk. The olfactory nerve communicates sensory information about the smells you experience to your brain.
The optic nerve is the visual nerve of which vision is connected. The nerve of the oculomotor has two distinct motor functions: muscle function and pupil response.
Now lets us find the solution from the given options-
In contrast to humans, frogs have ten pairs (20 numbers) of cranial nerves .
They grow from the brain and innervate into the various parts of the body.
In fact, they may be sensory, or motor.
They are – Olfactory, Optic, Oculomotor, Trochlear, Trigeminal, Abducens, Facial, Auditory, Glossopharyngeal, and Vagus. So, 10 pairs is the correct answer.
Frogs have ten pairs of cranial nerve i.e. 20 numbers. So, 15 pairs is an incorrect answer.
Compared to humans, frogs have ten pairs (20 numbers) of cranial nerves that have 12 pairs. So, 12 pairs is an incorrect answer. Thus, the option C is the incorrect option.
Frogs have 10 pairs of cranial nerves i.e. 20 numbers. So, 4 pairs is an incorrect answer.
Thus, the option D is the incorrect option.
Thus, the option A is the correct option.
Note: The cranial nerves are called parts of the peripheral nervous system ( PNS), while the olfactory (I), optic (II), and trigeminal (V) nerves are more properly considered component of the central nervous system ( CNS) at a structural level.
The motor nerves regulate muscle or gland movement and function.
