What part of the ear is responsible for static equilibrium?

Also found within the inner ear are the two equilibrium-detecting structures of the ear: the vestibule and the semicircular canals. The vestibule — a small, hollow region next to the cochlea — contains otolithic membranes that detect static equilibrium.

How does the utricle and saccule maintain equilibrium?

The saccule and utricle contain receptors that help maintain equilibrium. Equilibrium is maintained in response to two kinds of motion: Static equilibrium maintains the position of the head in response to linear movements of the body, such as starting to walk or stopping.

What does the saccule and utricle do?

The utricle and saccule are the two otolith organs in the vertebrate inner ear. They are part of the balancing system (membranous labyrinth) in the vestibule of the bony labyrinth (small oval chamber). They use small stones and a viscous fluid to stimulate hair cells to detect motion and orientation.

Does the utricle help with balance?

Loop-shaped canals in your inner ear contain fluid and fine, hairlike sensors that help you keep your balance. At the base of the canals are the utricle and saccule, each containing a patch of sensory hair cells.

What is the organ of static balance?

Hint: The ear is an acusto-static organ. This means that the ear helps in hearing (acusto), and balancing (static) of the body. The ear is subdivided into three main parts- external, middle, and internal ear.

Where are static equilibrium receptors located?

The receptors for static equilibrium are found in the maculae of the saccule and utricle. These receptors report on the position of the head in space.

What controls balance and equilibrium?

The vestibular system is the sensory apparatus of the inner ear that helps the body maintain its postural equilibrium. The information furnished by the vestibular system is also essential for coordinating the position of the head and the movement of the eyes.

How are utricle and Saccules different?

Both the utricle and the saccule provide information about acceleration. The difference between them is that the utricle is more sensitive to horizontal acceleration, whereas the saccule is more sensitive to vertical acceleration.

How does the ear maintain balance and equilibrium?

Many structures in the inner ear, called the vestibular system together, send signals to the brain, helping you to align yourself and keep your balance. Two parts of the inner ear called the utricle and the saccule track the head’s angular motions (from side to side and up and down), and sense gravity, too.

What helps with balance in the ear?

Canals that loop around your inner ear contain fluid and tiny hairlike sensors that help you maintain a sense of balance. The fluid moves up and down, letting your brain know which direction you’re facing….The bony network has three sections:

  • Cochlea.
  • Semicircular canals.
  • Vestibule.

How do you treat ear balance?


  1. Balance retraining exercises (vestibular rehabilitation). Therapists trained in balance problems design a customized program of balance retraining and exercises.
  2. Positioning procedures.
  3. Diet and lifestyle changes.
  4. Medications.
  5. Surgery.

How do we sense static equilibrium?

In static equilibrium, the position of the head is sensed while the head and body are still, maintaining stability. The organs of static equilibrium are located in the vestibule. The vestibular apparatus contains the equilibrium receptors in the semicircular canals and vestibule.
