Hearing receptors

Sensory receptors of hearing are hair cells, present on basilar membrane of cochlea. Sensory organ present on basilar membrane for hearing is formed by hair cells and the tissue is called Organ of Corti. Cochlea is a coiled structure. It is a bony tube on the outside, and a membranar tube is there on the inside.

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 for hearing?

Although hearing begins with the ear flap or pinna, the receptor cells that change sound energy into the electrical currency of the nervous system lie deep inside the temporal bone of the skull.

What are the receptors of inner ear?

The six receptors of the inner ear (cochlea, two otolith organs and three semicircular canals) share a common transduction unit made up of a sensory hair cell, a first order sensory neuron and the synapse between them.

What are the auditory receptors in human hearing?

There are two types of hair cells specific to the auditory system; inner and outer hair cells. Inner hair cells are the mechanoreceptors for hearing: they transduce the vibration of sound into electrical activity in nerve fibers, which is transmitted to the brain. Outer hair cells are a motor structure.
