Optic
The olfactory nerve (CN I) is the only cranial nerve directly attached to the cerebrum. It carries sensory information for smell from the nasal cavity to the brain.
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.
midbrain
The second cranial nerve is the optic nerve.
Smell impulses are carried by the cranial nerve called the olfactory nerve (cranial nerve I). It is responsible for transmitting information about odors from the nose to the brain.
The Olfactory nerve. CN1 Cranial Nerve I, or the first cranial nerve called the Olfactory nerve.
Its the first cranial nerve called the olfactory.
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 vagus nerve is the 10th cranial nerve, also known as cranial nerve X.
its serves the eye and it is called the "Optic Nerve".
The trochlear nerve (cranial nerve IV) is the only cranial nerve that emerges from the posterior aspect of the brainstem and decussates, forming a chiasmal pattern. It is responsible for the motor function of the superior oblique muscle of the eye.
Abducent nerve. Also called as abducens nerve. The sixth cranial nerve. Superior oblique muscle is supplied by trochlear nerve. All other muscles are supplied by oculomotor nerve.
