The inner ear is a minute complex fluidfilled structure surrounded by a bony labyrinth and located deep in the temporal bone.

The temporal bone is divided into several main partsportions 1-3. It has an ovular irregular shape and receives drainage from the semicircular ducts. The cochlea corresponds to the acoustic end organ and the vestibular end organs consist of the three semicircular canals with their ampullary tissue the saccule and the utricle.

Sense of balance and position is regulated by structures in the inner ear most notably the semicircular canals and the utricle and saccule in the vestibule. Your inner ear is the deepest part of your ear. The ear is the organ that enables hearing and in mammals body balance using the vestibular systemIn mammals the ear is usually described as having three partsthe outer ear the middle ear and the inner earThe outer ear consists of the pinna and the ear canalSince the outer ear is the only visible portion of the ear in most animals the word ear often refers to the external.

In mammals it consists of the bony labyrinth a hollow cavity in the temporal bone of the skull with a system of passages comprising two main functional parts. The middle ear and the internal or inner ear. The vestibular system of the inner ear provides a persons sense of balance and awareness of spatial orientation to coordinate body movements.

Inner Ear Anatomy. The Canalith Repositioning Procedure is also known as the Epley maneuver BPPV Benign Paroxysmal Positional Vertigo occurs as a result of displaced otoconia which are small crystals of calcium carbonate also referred to as otoliths or canaliths that are normally attached to the otolithic membrane in the utricle of the inner ear. Vestibular nerve enlarges to form the vestibular ganglion which then splits into superior and inferior parts to.

Anatomically the ear is divided into three major areas. Squamous part temporal squama. The inner ear has two special jobs.

The utricle is the larger of the two sacs and is located in the posterior-superior part of the vestibule. The temporal bone is one of the most important calvarial and skull base bones. It changes sound waves to electrical signals nerve impulses.

Gelatinous substance in the utricle and saccule of the inner ear that contains calcium carbonate crystals and into which the stereocilia of hair cells are embedded outer segment in the eye the section of a photoreceptor that contains opsin molecules that transduce light stimuli. Petrous part petrous pyramid. The anatomy of the vestibular apparatus balance portion of the inner ear The peripheral vestibular system the non-auditory portion has three semicircular canals that detect angular motion and two otolithic organs the utricle and saccule which detect linear acceleration and deceleration see figure 3.

The three semicircular canals correspond to the three dimensions x y and z and connect to the utricle at an ampullaa widening of the canal. An inner ear infection also may cause inflammation of the inner ear or labyrinthitis.

The inner ear is innervated by the vestibulocochlear nerve CN VIIIIt enters the inner ear via the internal acoustic meatus where it divides into the vestibular nerve responsible for balance and the cochlear nerve responsible for hearing. Anatomy of the Ear. The temporal bone is situated on the sides and the base of the cranium and lateral to the temporal lobe of the cerebrum.
