Uterus, Elliptical Sac (Utricle, Utriculus)

Uterus, Elliptical Sac (Utricle, Utriculus): description and functions

Utricle, Elliptical Sac (Utricle, Utriculus) is the largest of the two sacs that are located in the vestibular part of the membranous labyrinth of the inner ear. This sac is filled with endolymph, and on its inner surface there is a spot containing receptor cells that detect changes in the position of the body in space. This information is sent to the brain, where it is processed and used to control balance and orientation in space.

Utricle, Elliptical Sac (Utricle, Utriculus) plays an important role in maintaining balance and coordination of movements. It is part of the vestibular apparatus, which provides a person with a sense of balance and coordination of movements. When the head moves, the endolymph in the uterus and sac begins to move in the opposite direction, which causes a change in voltage in the receptor cells. This change in voltage is transmitted to the brain, where information about the position of the body in space is analyzed and processed.

But the uterus, the sac, is not only in the ear. Another important cavity, which has the same name, is located in the prostate gland of men. This cavity is called the prostatic utricle and opens into the prostatic part of the urethra. This small cavity has a diameter of about 6 mm and is an important anatomical element of the male reproductive system.

The function of the prostate uterus is to perform a secretory function, secreting a fluid that mixes with sperm and other secretions of the prostate gland to form ejaculate. This fluid contains enzymes and other substances that ensure the survival of sperm and promote their movement.

Thus, the uterus, elliptical pouch (Utricle, Utriculus) is an important element of the vestibular apparatus, providing a person with a sense of balance and coordination of movements. In addition, the prostate uterus is an important element of the male reproductive system, performing a secretory function and ensuring the survival of sperm.

Uterus, elliptical sacs (lat., Matricula, Muriellulus), small sacs at the base of the membrane. It is a large semilunar surface consisting of bone tissue and an elastic capsule. Both sacs are filled with endolymph. Receptors are located in the recess between the sacs.

The elliptical sacs are two small sacs located at the lower end of the membranes of the inner ear, which are the passageways for fluids and gases in our body. They are located in the pyramids of the membrane, from which seismosensory nerve fibers arise.

The saccules are located in the temporal part of the head and serve to provide sensory basismus vision while the head moves in relation to the spine. The elliptical sacs contain lateral canals running through them parallel to the major spiral and directed towards the mesopyrimidus. Consequently, the movement of the head causes the sacs to rotate, which leads to a change in pressure in these channels. These pressure changes result in stimulation of the sac receptors, which release a message to the brain about head movement. This value then passes to the cerebellum, which decides what position the head should take and sends impulses to the muscles of the head to make this movement. Thus, elliptical bagworms are a kind of “biological gyroscopes” that allow us to remain upright and determine which part of the head is on top.
