Study Notes
Vestibular System
- The cristae in the ampullae of the semicircular canals are responsible for detecting angular acceleration.
- The solution that fills the semicircular canals is called endolymph.
- The otolith organs (utricle and saccule) detect horizontal/lateral acceleration.
- The otolith organs (utricle and saccule) also detect vertical acceleration.
- The main component of the solution that fills the semicircular canals is potassium-rich fluid.
- The anterior canal is one of the three semicircular canals in the vestibular system; the others are the posterior and lateral canals.
Note: There are only three semicircular canals in the vestibular system, so the correct answer to the question "Which one of these is NOT a semicircular canal in the vestibular system?" would depend on the options provided.
Test your knowledge of the sensory components of the vestibular system with this quiz! Learn about the three semicircular canals, the endolymph solution, and the specific functions of the ampulla, utricle, and sacculus. Perfect for anyone interested in understanding how our body senses angular and linear accelerations.
