The inner ear consists of the bony labyrinth and membranous labyrinth. The bony labyrinth comprises three components: Cochlea: The cochlea is made of a hollow bone shaped like a snail and divided into two chambers by a membrane. Anatomy What are the parts of the inner ear? Your inner ear has three main parts: your cochlea, semi-circular canals (labyrinth) and your vestibule. Your cochlea supports your hearing and your vestibule and semi-circular canals support your balance. What is the cochlea?

The inner ear is embedded within the petrous part of the temporal bone, anterolateral to the posterior cranial fossa, with the medial wall of the middle ear, the promontory, serving as its lateral wall. The inner ear has two openings into the middle ear, both covered by membranes. The oval window lies between the middle ear and the vestibule, whilst the round window separates the middle ear from the scala tympani (part of the cochlear duct). Bony Labyrinth. The bony labyrinth is a series of bony cavities within the petrous part of the temporal.

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. Advertisement Inner ear: The inner ear, also called the labyrinth, operates the body's sense of balance and contains the hearing organ. A bony casing houses a complex system of membranous cells. The inner ear. In this diagram we visualise the inner ear. The cochlea is supplied by the cochlear nerve. The utricle, some of the saccule, the lateral semicircular canal and the superior semicircular canal are all supplied by the superior vestibular nerve. The posterior canal is supplied via the inferior vestibular nerve. 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.

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. The outer ear consists of the visible portion called the auricle, or pinna, which projects from the side of the head, and the short external auditory canal, the inner end of which is closed by the tympanic membrane, commonly called the eardrum. The function of the outer ear is to collect sound waves and guide them to the tympanic membrane.
The middle ear includes the eardrum, malleus, incus, and stapes. The inner ear includes semicircular canals, eustachian tube, cochlea, and vestibule and auditory nerves.">. 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.
What is a balance disorder? Hearing Link
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. 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.
