CANALIS SEMICIRCULARIS Meaning and
Definition
-
The canalis semicircularis is a term used in anatomy to refer to the semicircular canal, a vital structure located within the inner ear responsible for detecting changes in head movements and providing the body with a sense of balance and spatial orientation. It is one of three semicircular canals found in each ear and is an integral part of the vestibular system.
The canalis semicircularis is a narrow, tube-like structure lined with specialized sensory cells known as hair cells that detect the movement of fluid inside the canal. Connected to the vestibule, which is the central part of the inner ear, the three semicircular canals are positioned in different planes, allowing for the detection of movements in all three dimensions. Specifically, the canalis semicircularis detects rotational movements, such as when the head turns or rotates.
The movement of fluid within the canalis semicircularis initiates signals that are transmitted to the brain, providing important information about the position and movement of the head. This information is then integrated with visual cues and other sensory inputs to maintain balance and coordinate movements of the body. Dysfunction or damage to the canalis semicircularis can result in balance disorders, dizziness, vertigo, and other impairments in spatial orientation.

Semicircular canal, one of three canals (named according to their position superior, posterior, and lateral or external) in the labyrinth of the ear, which form loops of about two-t irds of a circle; they open into the vestibule by five openings, one aperture being the common opening of one extremity of each of two canals.
