Question

3rd, 6th and 11th cranial nerves are
A. Oculomotor, trigeminal and spinal
B. Optic, facial and spinal accessory
C. Oculomotor, abducens and spinal accessory
D. Trochlear, abducens and vagus

Answer 1

Hint: Our brain controls all the sensory, motor and autonomic reflexes in our body. There are various nerves/cells specialized in the brain to make this connection feasible and make our body to function. This well helps our body to work in coordination. Nerves in the brain are called cranial nerves.

Complete answer:
Our brain is connected to different parts of our body via these nerves called cranial nerves. There are 12 cranial nerves in our body, each having a particular function.
Cranial nerve 3 is the oculomotor nerve which helps the movement of muscles of eyes. It also helps with the involuntary functions of the eye.
Cranial nerve 6 is the abducens nerve which is connected to the optic nerve. It means they are leading to the vision and sight of sensory structures. It typically helps in the eye movements by helping lateral rectus muscles.
Cranial nerve 11 is an accessory nerve which helps the movement of the neck. It controls the trapezius muscles making the neck rotation and extension easy.
Option A: Oculomotor, trigeminal and spinal: cranial nerves 3, 5 and 11 are the respective nerves.
Option B: Optic, facial and spinal accessory: cranial nerves 2, 7 and 11 are the respective nerves.
Option C: Oculomotor, abducens and spinal accessory: the cranial nerve 3 is the oculomotor, 6 is the abducens and 11 is the spinal accessory cranial nerve.
Option D: Trochlear, abducens and vagus: Trochlear is the cranial nerve 4, abducens is the cranial nerve 6 and vagus is the cranial nerve 10.

Hence, the correct answer is option (C)

Note: These 12 pairs of cranial nerves are present in the higher vertebrates. Cranial nerve 1 – olfactory
Cranial nerve 2 - optic
Cranial nerve 3 - oculomotor
