Optic nerve
The second cranial nerve is the optic nerve.
Well you see bryan, the nerve that is right below the hair folical happens to be worth 12 cents.
The second cranial nerve is called the optic nerve. It carries visual information from the retina at the back of the eye to the visual centers in the brain, allowing us to process and interpret visual stimuli.
The nerves involved in diplopia include three cranial nerves: the oculomotor nerve (third cranial nerve), the abducens nerve (sixth cranial nerve), and the trochlear nerve (fourth cranial nerve).
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.
Cranial Nerve 2 - Optic Nerve
The second cranial nerve is the optic nerve.
Well you see bryan, the nerve that is right below the hair folical happens to be worth 12 cents.
The second cranial nerve is called the optic nerve. It carries visual information from the retina at the back of the eye to the visual centers in the brain, allowing us to process and interpret visual stimuli.
impulses travel down cranial nerve 2 to what lobe
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)
vestibulocochlear nerve
cranial nerve I: olfactory:smell cranial nerve II:optic:vision cranial nerve III: oculomotor: 4 of 6 eye muscles cranial nerve IV: trochlear: cranial nerve V: Trigeminal cranial nerve VI: Abducens cranial nerve VII: Facial cranial nerve VIII: Vestibulochlear: hearing cranial nerve IX: Grosspharnxgeal: saliva formation cranial nerve X: Vegus cranial nerve XI: Acessory Spinal: trapizious movement cranial nerve XII: Hypoglosseal: toungue movement
The parasympathetic fibers of the oculomotor nerve (cranial nerve III) control the contraction of the circular smooth muscle of the iris, causing pupil constriction.
The Olfactory nerve. CN1 Cranial Nerve I, or the first cranial nerve called the Olfactory nerve.
The nerves involved in diplopia include three cranial nerves: the oculomotor nerve (third cranial nerve), the abducens nerve (sixth cranial nerve), and the trochlear nerve (fourth cranial nerve).
The cranial nerves that are attached to the medulla oblongata are the glossopharyngeal, vagus, accessory and hypoglossal nerves. The glossopharyngeal nerve is the ninth cranial nerve that causes the tongue, throat, and parotid gland to function properly. The vagus nerve is the tenth cranial nerve which helps with motor production, mainly regarding the process of voice production. The accessory nerve is the eleventh cranial muscle whose only function is motor function, mainly regarding the trapezius and sternocledomastoid muscles. Lastly, the hypoglossal nerve is the twelfth cranial nerve which helps in the proper functioning of the muscles under the tongue.
