What is the excellent semicircular channel?

The excellent semicircular channel is one of the three semicircular channels found in the vestibular apparatus, an organ in the inner ear, which is responsible for a sense of balance or balance. The excellent semicircular channel is also called the front semicircular channel, oriented at right angles to the rear semicircular channel and lateral semicircular channel. Along with the other two semicircular channels, the higher semicircular channel is responsible for the detection of a rotary or angular acceleration and helps maintain balance and visual monitoring when the head is turned.

both semicircular channels and otolit organs belong to the vestibular system and are located inside the tubular structure. In this structure you can find endolymphs, fluid that is similar to fluid in cells or intracellular fluid. Otolites organs that include spending and saccule are responsible for detecting linear acceleration. The more than two channels have an excellent semicircular channel at one end of bulging or enlargement called andMpulla, a place where receptors for balance are called sensory hair cells. These hair cells have about 20 to 50 hair extensions, they are built into gelatin structure called Cupula, which helps to increase the sensitivity of hair cells to balance changes and are also associated with sensory nerve fibers that transmit nerve signals to the eighth skull nerve or vestibuloclear nerve. 6 Hair cells are bent in the direction of rotary force. For example, if the head turns left, endolymphs cause the cup to bend to the right, the result of the stimulation of hair cells.

As soon as the hair cell stimulation occurs, action potentials are generated and sensory neurons of the eighth skull nerve are activated. These neurons then transmit nerve signals to the cerebellar, brain stems and spinal cord. The brain stem, in particular the part called the Okulomotoric Center, reacts by controlling eye movements,While the spinal cord responds by stimulating the movement of the head, neck and limbs. The coordination of these different organs is needed to maintain and permit visual monitoring, such as what is happening when the head turns when reading or focusing on an object.
