Meaning
One of three tube loops filled with fluid and in planes nearly at right angles with one another; concerned with equilibrium.
Classification
Nouns denoting body parts.
Examples
- The inner ear contains three semicircular canals that are filled with a fluid called endolymph, which helps to detect changes in head movement.
- The semicircular canals are lined with hair cells that are connected to nerve fibers, which send signals to the brain to help maintain balance and equilibrium.
- Damage to the semicircular canals can cause vertigo and other balance-related problems, such as dizziness and disorientation.
- The semicircular canals work together with the otolith organs to help maintain equilibrium and balance, even when the body is in motion.
- Studies have shown that the semicircular canals are responsible for detecting rotational movements, while the otolith organs detect linear movements and changes in head position.
