Question

which cavity has its macula oriented appropriately to sense the linear movement of going up and down?
saccule
concha
ampulla
utricle

Explanation:

The saccule is a part of the inner ear's vestibular system. It contains a macula that is oriented vertically. This orientation allows it to detect linear acceleration in the vertical plane, such as the up - and - down movements. The utricle's macula is oriented horizontally and detects horizontal linear movements. The ampulla is related to rotational (angular) movements (semicircular canals). The concha is a part of the external ear (auricle) and has no role in detecting linear movements.

Answer:

Saccule
