from where the following nerves arise optic nerves and auditory nerve
Answers
Explanation:
Auditory nerve - The fibres of the cochlear never originate from an aggregation of nerve cell bodies in the spiral ganglion.
Optic nerve - An optic nerve begins at the optic disk, a structure that is 1.5mm in diameter and is located at the back of the eye.
Answer:
The optic nerves protrude from the diencephalon's side. They are sensory in nature and innervate the retina of the eye.
The auditory nerve travels from inner ear and exits through the temporal bone, a bone on the side of the skull, after passing through the brainstem and the inner ear.
Explanation:
Optic nerve:
More than 1 million nerve fibres make up the optic nerve, which carries visual information. One connects your brain to the retina at the rear of each eye. Loss of vision can occur when an optic nerve is damaged.
Auditory nerve:
The cranial nerve in charge of hearing is the cochlear nerve, commonly referred to as the acoustic or auditory nerve.
