Peripheral nerve interfaces are used for pain modulation, [7] restoration of motor function following spinal cord injury or stroke, [8] treatment of epilepsy by electrical stimulation of the vagus nerve, [9] nerve stimulation to control micturition, occipital nerve stimulation for chronic migraines and to interface with neuroprosthetics.
Nerve supply [ edit ] Sensation of the outer surface of the tympanic membrane is supplied mainly by the auriculotemporal nerve , a branch of the mandibular nerve ( cranial nerve V 3 ), with contributions from the auricular branch of the vagus nerve ( cranial nerve X ), the facial nerve (cranial nerve VII), and possibly the glossopharyngeal ...
The auriculotemporal nerve arises from the posterior division of [2]: 497 the mandibular nerve (CN V 3) (which is itself a branch of the trigeminal nerve (CN V)). [3] It arises by two roots [2]: 497 that circle around either side of the middle meningeal artery [1] [2]: 363 before uniting to form a single nerve.
The nerve reaches the surface by passing through the tympanomastoid fissure between the mastoid process and the tympanic part of the temporal bone, and divides into two branches: one joins the posterior auricular nerve. the other is distributed to the skin of the back of the ear (auricle) and to the posterior part of the ear canal.
It is often assumed the reflex is a vestigial Preyer reflex (also known as the pinna reflex). [ 6 ] [ 7 ] A study on auriculomotor activity found that in the presence of sudden, surprising sounds, the muscles around the ear closest to the direction of the sound would respond by moving involuntarily, causing the pinna to be pulled backwards and ...

To an impala, the pinna is useful in collecting sound. In animals, the function of the pinna is to collect sound, and perform spectral transformations to incoming sounds which enable the process of vertical localization to take place. [2] It collects sound by acting as a funnel, amplifying the sound and directing it to the auditory canal.
The visible part is called the auricle, also known as the pinna, especially in other animals.It is composed of a thin plate of yellow elastic cartilage, covered with integument, and connected to the surrounding parts by ligaments and muscles; and to the commencement of the ear canal by fibrous tissue.
