Hint: The cranial nerves are of 12 pairs in total. Every pair has a respective function for itself. Mainly their functions are classified into three types: sensory, motor, and mixed functions. A person can see, smell, and hear the things around them with the help of sensory cranial nerve cells. A person can maintain control over the muscles and its movements present around the neck and head of his or her body.
Complete answer:
- Trochlear is the shortest cranial nerve present in the human body.
- The trochlear nerve controls the superior oblique muscle of the eye. It emerges from the subsequent feature of the midbrain.
- The trochlear nerve turns forward and inward with the help of subarachnoid space in advance to the pierce of the dura mater. The dura mater present is adjacent to the posterior clinoid.
- The pons of the brainstem is the start of the abducens nerve. it enters an area called Dorello’s canal and explores through the cavernous sinus. It ends within the bony orbit, at the lateral rectus muscle.
- The longest cranial nerve present in the human body is called the Vagus nerve cell. The medulla is the starting point of this Vagus nerve cell and it is extended to the abdomen.
- Ophthalmia which is a part of the oculomotor nerve supports the control of muscle movements of the eyes. The oculomotor nerve affords the movements to most of the muscles that help in the movement of the eyeball and upper eyelid. It is the reason that these oculomotor nerves are known as extraocular muscles.
- Many of the doctors use stimulation therapy using the Vagus nerve to take care of various situations, together with depression, anxiety, and epilepsy.
Hence, the correct answer is option (A).
Note: We got to know that the Trochlear cranial nerve is the shortest nerve cell present in the human body. But it also has many more specialties within it. The trochlear cranial nerve consists of a smaller number of axons as compared to the other 12 pairs of cranial nerves. We can say that it is the only cranial nerve, which exits from the location of the dorsal part of the brainstem.
