  1. Semicircular canal

    A semicircular canal is one of three semicircular, interconnected tubes located inside each ear. The three canals are: ⁕the horizontal semicircular canal, ⁕superior semicircular canal, ⁕and the posterior semicircular canal. The semicircular ducts provide sensory input for experiences of rotary movements. They are oriented along the pitch, roll, and yaw axes. 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, while the superior and posterior canals detect vertical head movements. The semicircular canals are a component of the bony labyrinth. Among species of mammals, the size of the semicircular canals is correlated with their type of locomotion. Specifically, species that are agile and have fast, jerky locomotion have larger canals relative to their body size than those that move more cautiously.
