What else can I help you with?
Parasympathetic fibers of which nerve innervate smooth muscles of the lens of the eye - the eye muscles that cause the eye to bulge to accommodate close vision?
Optic
Can anabolic steroids damage your eyesight?
Yes it causes fluid to buildup on the ocular nerve which puts pressure on the nerve changing your vision
Which cranial nerve if damaged causes inability to see close?
The cranial nerve that, if damaged, can cause an inability to see close objects is the oculomotor nerve (cranial nerve III). Damage to this nerve can affect the movement of the eye muscles responsible for changing focus and adjusting the shape of the lens to see objects up close.
What cranial nerve deals with vision?
vestibulocochlear nerve
What part of vision is the optic nerve responsible for?
All of it
What are the potential causes and treatment options for a blurry optic nerve?
Potential causes of a blurry optic nerve can include conditions such as optic neuritis, glaucoma, or optic nerve damage. Treatment options may include medications, surgery, or lifestyle changes to manage the underlying cause and improve vision clarity. It is important to consult with a healthcare professional for a proper diagnosis and treatment plan.
How does damage to the optic nerve affect vision in the human eye?
Damage to the optic nerve can lead to vision problems because it is responsible for transmitting visual information from the eye to the brain. When the optic nerve is damaged, it can result in partial or complete loss of vision in the affected eye. This can manifest as blurry vision, blind spots, or even total blindness in severe cases.
Cranial nerves that have some function in vision include the?
The cranial nerves that have some function in vision include the optic nerve (II), which is responsible for carrying visual information from the eye to the brain, and the oculomotor nerve (III), which controls the movement of the eye muscles.
What nerve causes the diaphragm to contrct and initiate inhalation?
The phrenic nerve
Cranial nerve involved in vision and visual fields?
The optic nerve (purely sensory; carry afferent impulses for vision) Oculomotor (innervates four of the extrinsic eye muscles) Trochlear (innervates an extrinsic eye muscle that hooks through a pulley-shaped ligament in the orbit) Abducens (innervates the muscle that turns abducts the eyeball)
What causes occipital nerve headaches?
Occipital nerve headaches are caused by the firing of the occipital nerve either as the result of a process that disturbs the nerve or as the result of a chronic pain condition that causes spontaneous firing of the nerve pathways resulting in pain.
What causes a nerve impulse move along the nerve fiber?
Electrical diferences.
