Membrane of Corti

Membrane of Corti

Microcolumns of Corti are a physiological phenomenon of the human ear, consisting of a calcified degenerated neuritis of the auditory nerve innervating the internal auricular apparatus of the cochlea and the lateral process of the cochlea, which is called the small pyramid of the cochlea. These cells play the role of a mechanical system for amplifying sounds in the human body. They are also called "hammer action" due to the high frequency sound beyond the human perceptible range. They act like a strongman in a pear, connecting the eardrum to the eardrum of the brain. Since their discovery in 1954, these formations have become a major topic of research in the field of somatoacoustic pathology.

The amplitude-frequency response is a measure of its sound perception. This loudness of sound is due to the fact that the human ear begins to work only with a sound of significant volume compared to the noise of the environment. First of all, the microspeaker effect is caused by low electrical resistance, which serves to maintain strong polarization when stimulating external sound wave energy. As a result, the action potential amplitude evoked by electrical stimulation of the microcolumn can reach a peak amplitude of approximately −90 millivolts. These impulses are thought to act on a small proportion of the fibers of the internal auditory organ, which cause a specific sequence of action potentials within many fibers by a spinal ascending neuron projecting from the brainstem to the cerebral cortex. Purkinje cells of the cochlea are part of the cones of the cochlea, consisting of a bundle of aspen cells that connects the efferent fibers of the brain to the naru
