The utricle is a small, sac-like structure located in the vestibule of the inner ear. It is part of the vestibular system, which is responsible for balance. The utricle contains hair cells that are sensitive to movement. When the head moves, the hair cells bend, which sends signals to the brain. The brain interprets these signals to determine the direction and speed of head movement.
What is the function of the utricle?
The utricle helps to sense linear acceleration, which is the movement of the head in a straight line. For example, when you walk forward, the utricle senses the forward movement of your head. The utricle also helps to sense gravity. This is why you feel dizzy when you stand up too quickly.
What is the function of the utricle vs saccule?
The utricle and saccule are both sac-like structures located in the vestibule of the inner ear. They are both part of the vestibular system and help to sense balance. However, the utricle and saccule have different functions. The utricle senses linear acceleration, while the saccule senses angular acceleration. Angular acceleration is the movement of the head in a circle. For example, when you spin around, the saccule senses the circular movement of your head.
What is the utricle of the ear?
The utricle is one of the two otolith organs in the inner ear. The other otolith organ is the saccule. The utricle and saccule are responsible for sensing linear acceleration and angular acceleration, respectively. These organs are important for balance and spatial orientation.
Is utricle balance or hearing?
The utricle is part of the vestibular system, which is responsible for balance. The utricle does not play a role in hearing.
