Which three cranial nerves are purely or mostly sensory in function?

Which three cranial nerves are purely or mostly sensory in function?

There are three cranial nerves with primarily sensory function. Link to Sensory. Cranial nerve I, Olfactory, modulates smell, cranial nerve II, Optic,modulates vision. Cranial nerve VIII, Acoustovestibular, modulates hearing and balance.

Which cranial nerves are exclusively motor in function?

The trochlear, abducens, accessory, and hypoglossal nerves are only motor nerves; the trigeminal nerve is both sensory and motor; the oculomotor nerve is both motor and parasympathetic; the facial glossopharyngeal, and vagus nerves have sensory, motor, and parasympathetic components (Standring, 2008).

Which nerves are purely sensory in nature?

Cranial nerves I, II, and VIII are pure nerves of a sensory nature. Pure motor nerves are the cranial nerves III, IV, VI, XI, and XII. Mixed sensory and motor nerves are the cranial nerves V, VII, IX, and Z.

Which cranial nerves are purely sensory multiple choice question?

The optic (II), vestibulocochlear (VIII), and olfactory (I) nerves are purely sensory, whereas the oculomotor (III), trochlear (IV), abducens (VI), accessory (XI), and hypoglossal (XII) nerves are purely motor.

Which cranial nerves are pure sensory?

Cranial nerves I, II, and VIII are pure sensory nerves. Cranial nerves III, IV, VI, XI, and XII are pure motor nerves.

Is cranial nerve 3 sensory or motor?

Table of cranial nerves

No.	Name	Sensory, motor, or both
II	Optic	Sensory
III	Oculomotor	Mainly motor
IV	Trochlear	Motor
V	Trigeminal	Both sensory and motor

Which of the following nerves is purely a motor nerve?

Abducens nerve is purely a motor cranial nerve.

Which nerve is purely motor?

abducens nerve
The XII nerve is the hypoglossal nerve, it involves for the movement of most of the muscles of our tongue. Therefore, purely the motor nerve is abducens nerve as the rest of the nerves have both sensory and motor function.

What is the function of cranial nerve 3?

The oculomotor nerve is the third cranial nerve (CN III). It allows movement of the eye muscles, constriction of the pupil, focusing the eyes and the position of the upper eyelid.

Which of the following cranial nerves is purely?

Which is not a purely motor nerve?

The correct answer is D. Out of all the options, the cranial nerve with no motor function is the vestibulocochlear nerve (VIII). Since this nerve is purely sensory in function while the other options are purely motor in function.

Which cranial nerves are purely sensory?

Cranial nerves I, II, and VIII are pure sensory nerves. Cranial nerves III, IV, VI, XI, and XII are pure motor nerves. Cranial nerves V, VII, IX, and X are mixed sensory and motor nerves. The olfactory nerve (CN I) contains special sensory neurons concerned with smell.
