Oval saccule: balance receptors of the inner ear

The oval saccule is one of the sections of the membranous labyrinth of the inner ear, which plays an important role in maintaining the balance of the body. The inner ear consists of three main sections: the semicircular canals, which are involved in assessing changes in the angles and speeds of head rotation, and two sections responsible for assessing linear acceleration and the gravitational field - this is the saccula section and the oyster section, in which the oval sac is located.

The oval sac consists of a fluid-filled capsule and an internal group of cells called receptors. The receptors of the oval sac are sensitive to the gravitational field and accelerations caused by the movement of the body in space. When the position of the head or body changes, the receptors of the oval sac are deformed, which leads to a change in the current of nerve impulses transmitted to the brain.

The oval saccule is connected to other parts of the inner ear and brain that process information received from receptors. This information is used to maintain body balance and coordination of movements.

Dysfunction of the oval sac can lead to various balance problems such as dizziness, nausea and loss of coordination. These symptoms can occur with various diseases of the inner ear, such as labyrinthitis or Meniere's disease.

In conclusion, the oval sac is an important part of the inner ear, playing a key role in maintaining the balance of the body. The receptors in this department perceive changes in the gravitational field and acceleration caused by the movement of the body in space, and transmit information to the brain for processing. Dysfunction of the saccule ovalis can lead to serious balance problems, so it is important to see a doctor if symptoms occur.
