Question

What is the function of crista and macula in inner ear?

Answer 1

The crista ampullaris is the sensory organ of rotation. They are found in the ampullae of each of the semicircular canals of the inner ear, meaning that there are 3 pairs in total. The functionof the crista ampullaris is to sense angular acceleration and deceleration.


The vestibule is a region of the innerear which contains the saccule and the utricle, each of which contain a maculato detect linear acceleration. Themacula of saccule lies in a nearly vertical position. Its function is to detect vertical linear acceleration. It is a 2 mm by 3mm patch of hair cells.

Answer 2

Answer:

The function of crista and macula

It is as under-

The crista ampullaris and the macula are responsible for maintaining body balance and posture.

Explanation:

Function of crista-

• The crista ampullaris is the sensory organ of rotation.
• They are found in the ampullae of each of the semicircular canals of the inner ear.
• The function of the crista ampullaris is to sense angular acceleration and deceleration.

Function of the Maculae -

• In human ear: Vestibule. of sensory cells called a macula, which is about 2 mm (0.08 inch) in diameter.
• The macula monitors the position of the head relative to the vertical.
• In the utricle the macula projects from the anterior wall of that tubular sac and lies primarily in the horizontal plane.
