The anterior and posterior semicircular ducts are oriented vertically at right angles to each other. The lateral semicircular duct is about 30-degree angle from the horizontal plane. The orientations of the ducts cause a different duct to be stimulated by rotation of the head in different planes. Thus, the horizontal canal detects horizontal head movements (such as when you spin in a rotating chair), while the superior and posterior canals detect vertical head movements (such as when you bend forward to pick something up from the floor.
balance
They help to maintain balance of your body.
The fluid-filled canals that provide balance in the inner ear are called the semicircular canals. These canals detect angular acceleration and help the brain to maintain balance and spatial orientation.
Both of these are in the ear. The semi-circular canals help you to balance and the cochlea transmits nerve signals to the brain. This is how you hear. The inner ear is subdivided into the vestibule, semicircular canals, and cochlea. The semicircular canals and cochlea are separate structures with different functions. The receptors for balance are in the semicircular canals, and the organ of Corti (the organ of hearing) is in the cochlea.
The semicircular canals are responsible for dynamic equilibrium and more specifically angular acceleration. The anterior, posterior, and lateral semicircular ducts are the specific canals which detect rotational movements.
Inner ear
fluid
The semicircular canals of the inner ear send impulses to the brain regarding rotational movement and balance of the body. They help in maintaining equilibrium by detecting changes in head position.
The vestibular system in the inner ear, specifically the semicircular canals and otolith organs, gather information about the position of your body in space and help maintain balance.
the three fluid filled semi-circular canals. during movement, the fluid in the canals moves, causing the gelatinous materials and the hair cells in the ampulla to move. When the hair cells are bent, a nerve impulse is stimulated
The semicircular canals contain fluid and hair cells responsible for maintaining one's balance. For example, when a person tilts his head, the fluid in the semicircular canals also move. This movement is then detected by the hair cells and will in turn, send signals to the brain to keep the body's balance.
The sense of balance occurs in the inner ear, specifically in the vestibular system. This system includes the semicircular canals and otolith organs, which contain fluid and sensory cells that help detect changes in head position and movement. This information is then sent to the brain to maintain equilibrium and coordination.
