What else can I help you with?
Light shown into the eye will result in a decrease of the papillary diameter which nerves are involved in this reflex?
The autonomic nervous system is responsible for controlling the pupillary reflex. The parasympathetic nerves, specifically the oculomotor nerve (cranial nerve III), cause constriction of the pupils in response to light.
What cranial nerve that is involved in rolling the eyes?
The levator palpebrae muscle is primarily responsible for opening the eyelids, it is innervated by cranial nerve 3 (occulomotor nerve). Raising the eyebrows, which will also open the eyes wider and may be what you are asking about, is done by occipitofrontalis. This muscle is innervated by cranial nerve 7 (facial nerve).
What cranial nerve is the superior rectus?
The superior rectus muscle is innervated by the oculomotor nerve, which is cranial nerve III. This muscle is responsible for elevating the eye and assisting in adduction and medial rotation. Dysfunction of the oculomotor nerve can lead to issues with eye movement, including difficulty in elevating the eye.
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.
Which cranial nerve is responsible for adjusting amount of light entering eye?
The amount of light is actually controlled by the iris sphincter muscle, or the iris. It is controlled by parasympathetic fibers that originate from the Edinger-Westphal nucleus, travel along the oculomotor nerve (CN III), synapse in the ciliary ganglion, and then enter the eye via the short ciliary nerves.
What is facial synkinesis?
Facial synkinesis is the involuntary movement of facial muscles that accompanies purposeful movement of some other set of muscles.
What is the prognosis of facial synkinesis?
The prognosis of facial synkinesis is quite variable, depending largely on the prognosis of the underlying condition that caused its development.
What causes facila synkinesis?
Facial synkinesis can follow any injury or condition causing palsy or paralysis of the facial nerve. The most common associated disorder is Bell's palsy.
What cranial nerve is chiefly responsible for eye movements?
oculomotor, trochlear, abducens
What is the function of the oculomotor nerve?
oculomotor nerve control the muscle that move the eyeball.close visionMovement of the eyes.Focusing the eyes on close objects.
Which cranial nerve is used when raising the eyebrows?
oculomotor
Cranial nerve raising eyelid?
number III. oculomotor
Does the oculomotor nerve have motor fibers?
Yes it is motor and parasympathetic.
What words start with the prefix ocu?
Ocular Binocular Oculus Oculist Oculomotor Ocularist Monocular
The oculomotor nerve controls most of the movement of what part of your body?
Eye
Can External strabismus and ptosis be caused by damage to the oculomotor nerve?
yes
Which cranial nerve control contraction of the circular smooth muscle of the iris?
The parasympathetic fibers of the oculomotor nerve (cranial nerve III) control the contraction of the circular smooth muscle of the iris, causing pupil constriction.
