Tragal pressure is pressure that is applied to the cartilage at the front, or anterior aspect of the ear canal (called the tragus), closing the canal and increasing pressure on the tympanic membrane (ear drum). [1] Tragal pumping is the act of repeatedly applying tragal pressure in quick succession to help deliver ear drops deeper into the ear ...
In humans, it is a small tubercle on the visible part of the ear, the auricle. The antitragus is located just above the earlobe and points anteriorly. It is separated from the tragus by the intertragic notch. The antitragicus muscle, an intrinsic muscle of the ear, arises from the outer part of the antitragus. [1] [2]
The tragus is a key feature in many bat species. As a piece of skin in front of the ear canal, it plays an important role in directing sounds into the ear for prey location and navigation via echolocation. [6] Because the tragus tends to be prominent in bats, it is an important feature in identifying bat species. [7]
Otitis externa, also called swimmer's ear, [1] is inflammation of the ear canal. [2] It often presents with ear pain, swelling of the ear canal, and occasionally decreased hearing. [2] Typically there is pain with movement of the outer ear. [3] A high fever is typically not present except in severe cases. [3]
The auricular branch of the vagus nerve is often termed the Alderman's nerve ("a reference to the old Aldermen of the City of London and their practice of using rosewater bowls at ceremonial banquets, where attendees were encouraged to place a napkin moistened with rosewater behind their ears in the belief that this would aid digestion") or Arnold's nerve (an eponym for Friedrich Arnold).
Secondary ear pain is a type of referred pain, meaning that the source of the pain differs from the location where the pain is felt. Primary ear pain is more common in children, whereas secondary (referred) pain is more common in adults. [13] Primary ear pain is most commonly caused by infection or injury to one of the parts of the ear. [3]
“Non-cardiac pain on the left side usually will present itself as pain that lasts for a few seconds or can be reproduced by pressing on your chest,” says Raj Khandwalla, MD, director of ...
Inner ear decompression sickness, (IEDCS) or audiovestibular decompression sickness is a medical condition of the inner ear caused by the formation of gas bubbles in the tissues or blood vessels of the inner ear. Generally referred to as a form of decompression sickness, it can also occur at constant pressure due to inert gas counterdiffusion ...
