Question

Which five organs make up the vestibular system? A. Three semicircular canals and two otolith organs B. Two semicircular canals and three otolith organs C. One semicircular canal and four otolith organs D. Four semicircular canals and one otolith organ E. Five semicircular canals

Answer 1

A. Three semicircular canals and two otolith organs

Step-by-step explanation:

The vestibular system is the sensory system found in the inner ear. It helps in the coordination of balance and movement.

The vestibular system consists of two major parts : the semicircular canals which is responsible for rotational movements and are Three in number and the Otolith organ which is responsible for linear acceleration and are 2 in number.

The vestibular system sends signals mainly to the neural structures that control eye movements and to the muscles that keep an animal or human in their general control posture.

Answer 2

Option A

Step-by-step explanation:

The vestibular system is a part of the inner ear that provides the most important contribution to the sense of balance and coordinating movement with balance. This system is made up of two parts which are the three semicircular canals and the two otolith organs. The two otolith organs are the saccule and the utricle. The utricle is sensitive to changes with regards to horizontal movement and the saccule provides information about vertical acceleration. They are able to do this due to their orientation in the inner ear providing spatial orientation with regards to movement and balance. the three semi circular canals includes the horizontl, poterior and the superior semicircular canals. they provide sensory inputs.
