The Anatomy of the Ear LEONELLO CALVETTI / Getty Images Anatomy Structure The ear is made up of the outer ear, middle ear, and inner ear. The inner ear consists of the bony labyrinth and membranous labyrinth. The bony labyrinth comprises three components: What is the inner ear? What we think of as the "ear" is actually a three-part structure. The outer ear is the part you see and your ear canal. The middle ear is a box-shaped area behind the tympanic membrane (eardrum) that includes the three smallest bones in your body.

Fig 1 - Overview of the ear Anatomical Position and Structure The inner ear is located within the petrous part of the temporal bone. It lies between the middle ear and the internal acoustic meatus, which lie laterally and medially respectively. The inner ear has two main components - the bony labyrinth and membranous labyrinth.

How We Perceive Sound
Ear Anatomy - Inner Ear Next to the middle ear in the bone of the skull is a small compartment which contains the hearing and balance apparatus known as the inner ear. The inner ear has two main parts. The cochlea , which is the hearing portion, and the semicircular canals is the balance portion. Overview Your outer ear and middle ear are separated by your eardrum, and your inner ear houses the cochlea, vestibular nerve and semicircular canals (fluid-filled spaces involved in balance and hearing). What is the ear? Your ears are organs that detect and analyze sound. Located on each side of your head, they help with hearing and balance. Inner ear anatomy. The outer, middle, and inner ear. The inner ear is at the end of the ear tubes. It sits in a small hole-like cavity in the skull bones on both sides of the head. The inner ear. Labelled Diagram of Inner Ear Inner Ear - Description The inner ear or labyrinth of the human ear comprises 2 structures - the bony labyrinth and the membranous labyrinth. Bony labyrinth is a series of cavities or channels present in the petrous part of the temporal bone. The membranous labyrinth is present within the bony labyrinth.

Anatomy. The inner ear is a complex three dimensional shape with semicircular canals, dilations called the utricle and saccule and a spiral portion known as the cochlea. All of these organs are housed inside a bony shell known as the bony labyrinth and this is within the temporal bone. The cochlea is the site where sound is transformed into. Inner and Middle Ear. The cochlea is the most critical component of the inner ear. It is divided into three fluid-filled chambers, called scalae, that spiral around a bony core. The scala media.
human ear, organ of hearing and equilibrium that detects and analyzes sound by transduction (or the conversion of sound waves into electrochemical impulses) and maintains the sense of balance (equilibrium). Understand the science of hearing and how humans and other mammals perceive sound How humans and other mammals perceive sound. inner ear, part of the ear that contains organs of the senses of hearing and equilibrium.The bony labyrinth, a cavity in the temporal bone, is divided into three sections: the vestibule, the semicircular canals, and the cochlea.Within the bony labyrinth is a membranous labyrinth, which is also divided into three parts: the semicircular ducts; two saclike structures, the saccule and utricle.

The fluid inside the cochlea, which is a spiral-shaped, fluid-filled structure in the inner ear, is called perilymph. Perilymph is one of the two types of fluid found in the cochlea, the other being endolymph. These fluids play a crucial role in the process of hearing by transmitting sound vibrations and stimulating the hair cells in the cochlea. Ear Anatomy - Inner Ear. Ear Anatomy Schematics.
