Semicircular canals2

• The inner ear contains the otolith organs-the utricle and saccule-and the semicircular canals belonging to the vestibular system, as well as the cochlea of the auditory system. (wikipedia.org)
• The neurosensory structures involved in hearing and equilibrium are located in the membranous labyrinth: the organ of Corti is located in the cochlear canal, while the maculae of the utricle and the saccule and the ampullae of the semicircular canals are located in the posterior section. (cloudaccess.net)

Vestibular system2

• An ear is the organ that enables hearing and (in mammals) body balance using the vestibular system. (wikipedia.org)
• The ear is a very complex network of structures which contribute both to our sense of hearing as well as balance, i.e the vestibular system. (mskneurology.no)

Ossicles5

• The middle ear includes the tympanic cavity and the three ossicles. (wikipedia.org)
• The middle ear contains the three small bones-the ossicles-involved in the transmission of sound, and is connected to the throat at the nasopharynx, via the pharyngeal opening of the Eustachian tube. (wikipedia.org)
• The ossicles are three small bones that function together to receive, amplify, and transmit the sound from the eardrum to the inner ear. (wikipedia.org)
• The three ossicles transmit sound from the outer ear to the inner ear. (wikipedia.org)

Inner ear7

• In mammals the ear is usually described as having three parts: the outer ear, the middle ear and the inner ear. (wikipedia.org)
• The human ear consists of three parts-the outer ear, middle ear and inner ear. (wikipedia.org)
• The middle ear lies between the outer ear and the inner ear. (wikipedia.org)
• It has a natural secretion of cerumen (ear wax) that protects the canal and prevents unwanted entities or particles to enter it, thus protecting the eardrum and middle & inner ear segments. (mskneurology.no)
• The inner ear consists of the cochlea, the vestibular labyrinth, and the vestibulocochlear nerve. (mskneurology.no)

• The middle ear also connects to the upper throat at the nasopharynx via the pharyngeal opening of the Eustachian tube. (wikipedia.org)
• The middle ear involves the parts between the ear drum and the oval window of the cochlea. (mskneurology.no)
• This transport mechanism (i.e the mucociliary transport mechanism) drains mucus away from the middle ear, and into the nasopharynx via the eustachian tube, thus preventing infection from occurring in the middle ear. (mskneurology.no)
• Increased pressure in the middle ear, usually due to inability of the eustachian tube to open, will restrict vibrations in the eardrum and thus also dampen hearing. (mskneurology.no)
• The middle ear consists of the tympanic cavity, an air-filled cavity whose outer walls form the tympanic membrane (eardrum), and communicates proximally with the nasopharynx by the Eustachian tubes, which maintain pressure equilibrium on either side of the tympanic membrane. (cloudaccess.net)

External ear2

• The ear muscles are supplied by the facial nerve, which also supplies sensation to the skin of the ear itself, as well as to the external ear cavity. (wikipedia.org)
• The external ear, also called the 'pinna' or 'auricle', is designed mainly to capture the sound waves. (mskneurology.no)

Canal9

• The outer ear consists of the pinna and the ear canal. (wikipedia.org)
• The outer ear is the external portion of the ear and includes the fleshy visible pinna (also called the auricle), the ear canal, and the outer layer of the eardrum (also called the tympanic membrane). (wikipedia.org)
• The pinna consists of the curving outer rim called the helix, the inner curved rim called the antihelix, and opens into the ear canal. (wikipedia.org)
• The tragus protrudes and partially obscures the ear canal, as does the facing antitragus. (wikipedia.org)
• The hollow region in front of the ear canal is called the concha. (wikipedia.org)
• The ear canal stretches for about 1 inch (2.5 cm). (wikipedia.org)
• The skin surrounding the ear canal contains ceruminous and sebaceous glands that produce protective ear wax. (wikipedia.org)
• The ear canal ends at the external surface of the eardrum. (wikipedia.org)
• The outer ear consists of the auricle, a cartilaginous skin-covered structure, and the external auditory canal, an irregularly-shaped cylinder approximately 25 mm long which is lined by glands secreting wax. (cloudaccess.net)

Eardrum1

• The eustachian tube's main role is to equalize the pressure between the in- and outside of the ear, i.e on both sides of the eardrum. (mskneurology.no)

Muscles1

• Two sets of muscles are associated with the outer ear: the intrinsic and extrinsic muscles. (wikipedia.org)

Infection1

• The ear may be affected by disease, including infection and traumatic damage. (wikipedia.org)

Lies1

• the outer ear lies outside the skull, while the other two parts are embedded in the temporal bone (figure 1). (cloudaccess.net)

Parts1

• The great auricular nerve, auricular nerve, auriculotemporal nerve, and lesser and greater occipital nerves of the cervical plexus all supply sensation to parts of the outer ear and the surrounding skin. (wikipedia.org)

Opening of the Eustachian tube2

• The middle ear contains the three small bones-the ossicles-involved in the transmission of sound, and is connected to the throat at the nasopharynx, via the pharyngeal opening of the Eustachian tube. (wikipedia.org)
• The middle ear also connects to the upper throat at the nasopharynx via the pharyngeal opening of the Eustachian tube. (wikipedia.org)

Tympanic6

• The outer ear is the external portion of the ear and includes the fleshy visible pinna (also called the auricle), the ear canal, and the outer layer of the eardrum (also called the tympanic membrane). (wikipedia.org)
• The middle ear is filled with air and acts as a cushion behind the tympanic (drum) membrane. (evokedpotential.com)
• M echanical transduction (middle ear ossicles) matches tympanic and hydraulic impedance. (evokedpotential.com)
• Mechanical displacement of the tympanic membrane, produced by changes in sound pressure waves, is transmitted to the inner ear by tiny bones termed the middle ear ossicles. (evokedpotential.com)

Pinna3

• The outer ear consists of the pinna and the ear canal. (wikipedia.org)
• The pinna consists of the curving outer rim called the helix, the inner curved rim called the antihelix, and opens into the ear canal. (wikipedia.org)
• The ear consists of the outer ear (pinna), middle ear (external auditory meatus) and inner ear (cochlea) where the transduction (processing) of sound occurs. (evokedpotential.com)

Outer ear7

• In mammals the ear is usually described as having three parts: the outer ear, the middle ear and the inner ear. (wikipedia.org)
• Since the outer ear is the only visible portion of the ear in most animals, the word "ear" often refers to the external part alone. (wikipedia.org)

• Two sets of muscles are associated with the outer ear: the intrinsic and extrinsic muscles. (wikipedia.org)

• The middle ear lies between the outer ear and the inner ear. (wikipedia.org)
• Sound waves are captured by the outer ear which are funneled into the external auditory meatus which functions as an impedance transformer that facilitates transmission of airborne sound into vibrations of the fluid in the cochlea. (evokedpotential.com)

Cavity1

External1

• The ear canal ends at the external surface of the eardrum. (wikipedia.org)

Brain2

• Diseases of the ear may lead to hearing loss, tinnitus and balance disorders such as vertigo, although many of these conditions may also be affected by damage to the brain or neural pathways leading from the ear. (wikipedia.org)
• The brain accomplishes this by comparing arrival-times and intensities from each ear, in circuits located in the superior olivary complex and the trapezoid bodies which are connected via pathways to both ears. (wikipedia.org)

Sound2

• The ears of vertebrates are placed somewhat symmetrically on either side of the head, an arrangement that aids sound localization. (wikipedia.org)
• The symmetrical arrangement of the two ears allows for the localisation of sound. (wikipedia.org)
