If the light is shining directly into one eye, then the pupil in that eye will constrict (a direct response), but so will the pupil in the non-illuminated eye (a consensual response). This reflex involves two cranial nerves: the optic nerve, which senses the light, and the oculomotor nerve, which constricts both pupils.
What else can I help you with?
Cranial nerve for sense of hearing?
The vestibulocochlear cranial nerve controls hearing.
Which cranial nerve innervates the ear?
The cranial nerve that innervates the ear is the vestibulocochlear nerve (CN VIII). It has two branches: the vestibular nerve that controls balance and the cochlear nerve that controls hearing.
What cranial nerve controls the ears?
auditory nerve
What cranial nerve is used when smelling a flower?
The Olfactory nerve. CN1 Cranial Nerve I, or the first cranial nerve called the Olfactory nerve.
Which cranial nerve controls hearing and body balance?
The cranial nerve that controls hearing and body balance is the vestibulocochlear nerve, also known as cranial nerve VIII. It has two main branches: the cochlear branch, responsible for hearing, and the vestibular branch, responsible for balance and spatial orientation.
Which cranial nerve in responsible for the reflex constriction of the pupil in response to light and accomodation?
The oculomotor nerve (cranial nerve III) is responsible for the reflex constriction of the pupil in response to light and accommodation.
Which cranial nerve controls the sensation of hunger and GI discomfort?
The Trigminal Nerve (V)
Which cranial nerve controls the heart and lungs?
CN X (Vagus)
Are the eyelid controlled by cranial nerve?
Occulomotor nerve (CN III) controls levator palpebrae so yes, the eyelids are controlled by cranial nerves.
What cranial nerve controls the abdominal visceral organs?
Vagus (X)
What cranial nerve controls sneezing reflex?
Nervus trigeminus (V)
What cranial nerve involved while raising eye lids and focusing the lens of the eye for accommodation?
The cranial nerve involved in raising the eyelids is the oculomotor nerve (cranial nerve III). For focusing the lens of the eye for accommodation, the oculomotor nerve controls the ciliary muscle.
