What contains the receptors for hearing?

What contains the receptors for hearing?

The cochlea is filled with two fluids (endolymph and perilymph), inside the cochlea is the sensory receptor — the Organ of Corti — which contains sensory cells with hair-like structures (hair cells) that are the nerve receptors for hearing.

What are the receptors for hearing called?

The organ for hearing, which contains the sensory receptors is known as the spiral organ of Corti and is located throughout the cochlear duct. The organ of Corti is composed of a lower basilar membrane against the scala tympani and an upper tectorial membrane within the cochlear duct (Fig. 8.41).

Where are the receptors found for hearing?

The cochlea is a fluid-filled, snail-shaped structure that contains the sensory receptor cells (hair cells) of the auditory system (Figure 1).

What is the fluid in the cochlea called?

The cochlea is filled with fluid. Specifically, the scala vestibuli and scala tympani contain a fluid called perilymph, which is similar in composition to cerebrospinal fluid, and the scala media contains endolymph, which more resembles intracellular fluid in terms of its ionic concentrations.

Which structure of the ear contains the receptors of hearing?

This action is passed onto the cochlea, a fluid-filled snail-like structure that contains the organ of Corti, the organ for hearing. It consists of tiny hair cells that line the cochlea. These cells translate vibrations into electrical impulses that are carried to the brain by sensory nerves.

Which is the sound receptor?

On this membrane sit the stars of the show in the auditory system, the auditory receptor cells, or hair cells. When the basilar membrane moves, it stimulates the hair cells, which then send signals about sounds to the brain. The pinna captures sound waves and channels them through the ear canal to the eardrum.

Is there liquid in your ears?

Most of the time, your ears discharge earwax. This is an oil that your body naturally produces. The job of earwax is to make sure that dust, bacteria, and other foreign bodies don’t get into your ear. However, other conditions, such as a ruptured eardrum, can cause blood or other fluids to drain from your ear.

Is there liquid in the inner ear?

Loop-shaped canals in your inner ear contain fluid and fine, hairlike sensors that help you keep your balance. At the base of the canals are the utricle and saccule, each containing a patch of sensory hair cells.

What structure contains the receptors for the sense of hearing quizlet?

The structure in the vertebral inner ear that contains auditory receptors; also called organ of Corti.

Which type of receptor is responsible for hearing and equilibrium?

hair cell
Both hearing and equilibrium rely on a very specialized type of receptor called a hair cell. There are six groups of hair cells in each inner ear: one in each of the three semicircular canals, one in the utricle, one in the saccule, and one in the cochlea.

Where are hearing receptors located quizlet?

A snail-shaped structure in the inner ear that contains the primary receptor cells for hearing.
