Anterior auricular branches
The anterior auricular branches of the superficial temporal artery are distributed to the anterior portion of the auricula, the lobule, and part of the external meatus, anastomosing with the posterior auricular.
See Ear canal and Anterior auricular branches
Apocrine sweat gland
An apocrine sweat gland (from Greek apo 'away' and krinein 'to separate') is composed of a coiled secretory portion located at the junction of the dermis and subcutaneous fat, from which a straight portion inserts and secretes into the infundibular portion of the hair follicle.
See Ear canal and Apocrine sweat gland
Atresia
Atresia is a condition in which an orifice or passage in the body is (usually abnormally) closed or absent.
Auricle (anatomy)
The auricle or auricula is the visible part of the ear that is outside the head. Ear canal and auricle (anatomy) are Auditory system and ear.
See Ear canal and Auricle (anatomy)
Auricular branch of vagus nerve
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).
See Ear canal and Auricular branch of vagus nerve
Auriculotemporal nerve
The auriculotemporal nerve is a sensory branch of the mandibular nerve (CN V3) that runs with the superficial temporal artery and vein, and provides sensory innervation to parts of the external ear, scalp, and temporomandibular joint.
See Ear canal and Auriculotemporal nerve
Bacteria
Bacteria (bacterium) are ubiquitous, mostly free-living organisms often consisting of one biological cell.
Cholesteatoma
Cholesteatoma is a destructive and expanding growth consisting of keratinizing squamous epithelium in the middle ear and/or mastoid process. Ear canal and Cholesteatoma are Audiology, ear and Otology.
See Ear canal and Cholesteatoma
Conductive hearing loss
Conductive hearing loss (CHL) occurs when there is a problem transferring sound waves anywhere along the pathway through the outer ear, tympanic membrane (eardrum), or middle ear (ossicles). Ear canal and Conductive hearing loss are Audiology and Otology.
See Ear canal and Conductive hearing loss
Contact dermatitis is a type of acute or chronic inflammation of the skin caused by exposure to chemical or physical agents.
See Ear canal and Contact dermatitis
Deep cervical lymph nodes
The deep cervical lymph nodes are a group of cervical lymph nodes in the neck that form a chain along the internal jugular vein within the carotid sheath.
See Ear canal and Deep cervical lymph nodes
Ear mite
Ear mites are mites that live in the ears of animals.
Eardrum
In the anatomy of humans and various other tetrapods, the eardrum, also called the tympanic membrane or myringa, is a thin, cone-shaped membrane that separates the external ear from the middle ear. Ear canal and eardrum are Auditory system, ear and Otology.
Earplug
An earplug is a device that is inserted in the ear canal to protect the user's ears from loud noises, intrusion of water, foreign bodies, dust or excessive wind. Ear canal and earplug are Audiology.
Earwax
Earwax, also known by the medical term cerumen, is a waxy substance secreted in the ear canal of humans and other mammals. Ear canal and Earwax are ear.
External jugular vein
The external jugular vein receives the greater part of the blood from the exterior of the cranium and the deep parts of the face, being formed by the junction of the posterior division of the retromandibular vein with the posterior auricular vein.
See Ear canal and External jugular vein
Fungus
A fungus (fungi or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms.
Granuloma
A granuloma is an aggregation of macrophages (along with other cells) that forms in response to chronic inflammation.
Great auricular nerve
The great auricular nerve is a cutaneous (sensory) nerve of the head.
See Ear canal and Great auricular nerve
Insect
Insects (from Latin insectum) are hexapod invertebrates of the class Insecta.
List of glands of the human body
This article contains a list of glands of the human body.

Middle ear
The middle ear is the portion of the ear medial to the eardrum, and distal to the oval window of the cochlea (of the inner ear). Ear canal and middle ear are Audiology, Auditory system, ear and Otology.
Myiasis
Myiasis, also known as flystrike or fly strike, is the parasitic infestation of the body of a live animal by fly larvae (maggots) that grow inside the host while feeding on its tissue.
Osteoma
An osteoma (plural osteomas or less commonly osteomata) is a new piece of bone usually growing on another piece of bone, typically the skull.
Otitis externa
Otitis externa, also called swimmer's ear, is inflammation of the ear canal.
See Ear canal and Otitis externa
Otomycosis
Otomycosis is a fungal ear infection, a superficial mycotic infection of the outer ear canal caused by micro-organisms called fungi which are related to yeast and mushrooms.
Outer ear
The outer ear, external ear, or auris externa is the external part of the ear, which consists of the auricle (also pinna) and the ear canal. Ear canal and outer ear are Auditory system, ear and Otology.
Pharyngeal arch
The pharyngeal arches, also known as visceral arches, are structures seen in the embryonic development of vertebrates that are recognisable precursors for many structures.
See Ear canal and Pharyngeal arch
Posterior auricular artery
The posterior auricular artery is a small artery that arises from the external carotid artery.
See Ear canal and Posterior auricular artery
Pterygoid plexus
The pterygoid plexus (from Greek pteryx, "wing" and eidos, "shape") is a fine venous plexus upon and within the lateral pterygoid muscle.
See Ear canal and Pterygoid plexus
Scar
A scar (or scar tissue) is an area of fibrous tissue that replaces normal skin after an injury.
Stenosis
Stenosis is the abnormal narrowing of a blood vessel or other tubular organ or structure such as foramina and canals.
Superficial cervical lymph nodes
The superficial cervical lymph nodes are lymph nodes that lie near the surface of the neck.
See Ear canal and Superficial cervical lymph nodes
Superficial temporal vein
The superficial temporal vein is a vein of the side of the head which collects venous blood from the region of the temple. It arises from an anastomosing venous plexus on the side and vertex of the head.
See Ear canal and Superficial temporal vein
Tympanostomy tube
Tympanostomy tube, also known as a grommet, myringotomy tube, or pressure equalizing tube, is a small tube inserted into the eardrum via a surgical procedure called myringotomy to keep the middle ear aerated for a prolonged period of time, typically to prevent accumulation of fluid in the middle ear. Ear canal and Tympanostomy tube are Audiology.
