What is the inner ear also called?
The scientific name for the inner ear is labyrinth. It is divided into two main parts which are membranous labyrinth and bony labyrinth.
What other name is the inner ear known as?
Inner ear or internal ear is also called the labyrinth.
What is the labyrinth?
a tortuous anatomical structure; especially : the inner ear or its bony or membranous part -- see BONY LABYRINTH, MEMBRANOUS LABYRINTH ; the cavity in the petrous portion of the temporal bone that contains the membranous labyrinth of the inner ear -- called also osseous labyrinth
Where in the body is the labyrinth?
The earThe labyrinth can actually be found inside your ear. There are three sections of the ear. They are the outer ear (the part we see along the sides of our head.) The middle ear and the inner ear. But in terms of function, the ear has four parts: those three and the brain. This means that hearing involves all parts of the ear as well as the auditory cortex of the brain. The external ear helps concentrate the vibrations of air on the ear drum and make it vibrate. These vibrations are transmitted by a chain of little bones in the middle ear to the inner ear. There they stimulate the fibres of the auditory nerve to transmit impulses to the brain.The internal ear, where you will find the labyrinth, is a highly complex thing. The essential component of the inner ear for hearing is the membranous labyrinth where the fibres of the auditory nerve (the nerve connecting the ear to the brain) end. The membranous labyrinth is a system of communicating sacs and ducts (tubes) filled with fluid (the endolymph). The membranous labyrinth is lodged within a cavity called the bony labyrinth. At some points the membranous labyrinth is attached to the bony labyrinth and at other points the membranous labyrinth is suspended in a fluid (the perilymph) within the bony labyrinth.To make it even more confusing, the bony labyrinth has three parts: a central cavity, semicircular canals, and the cochlea.Inner ear
What is the tube leading from the auricle to the middle ear called?
The tube leading from the auricle (outer ear) to the middle ear is called the Eustachian tube. It helps to equalize pressure between the middle ear and the atmospheric pressure, allowing for proper hearing and function of the ear. This tube also drains fluid from the middle ear to the throat.
The bony labyrinth is another name for the structure called?
The bony labyrinth refers to the system of bony cavities in the inner ear that house the cochlea, vestibule, and semicircular canals.
The fluid of the inner ear contained within the bony labyrinth and surrounding the membranous labyrinth?
The fluid of the inner ear, called perilymph, is contained within the bony labyrinth of the cochlea and vestibular system while surrounding the membranous labyrinth, which contains endolymph. Perilymph helps transmit sound vibrations and maintains balance within the inner ear.
What is progressive deafness due to ossification in the bony labyrinth of the inner ear called?
otosclerosis
Which section of the ear is the eardrum in?
The tympanic membrane (eardrum) is the division of the outer and middle ear. The middle ear is sometimes called the tympanic chamber, so the eardrum is officially designated to the middle ear.
What are the three layers of the inner ear?
The three layers of the inner ear are the bony labyrinth, the membranous labyrinth, and the endolymphatic space. The bony labyrinth provides structural support, the membranous labyrinth contains the sensory organs for hearing and balance, and the endolymphatic space contains fluid that helps with sensory perception of sound and balance.
Name of the fluid in the human ear?
For the most part the Ear does not contain any fluid, the Outer and Middle Ear are air filled this is why we have the pharyngotympanic tube. The inner ear however is very complicated and difficult to explain. It has two Labyrinths, the Bony Labyrinth and, suspended within the bony labyrinth, the Memranous Labarynth. These labyrinths make up the shapes most people know as the Cochlea and the Semi-Circular Canals (both labyrinth types are present in each). The membranous labarynth contains a fluid called Endolymph and the Bony cavity contains a similar fluid called Perilymph.
What membrane is also known as the eardrum?
a thin membrane separating the middle ear from the inner part of the external auditory canal that vibrates in response to sound energy and transmits the resulting mechanical vibrations to the structures of the middle ear -- called also eardrum,tympanum It is the ear drum.
