Biology - Neural Control and Coordination Question with Solution | TestHub
Given below are two statements, one is labelled as Assertion (A) and other one labelled as Reason (R).
Assertion (A): The vestibule consists of utriculus and sacculus.
Reason (R): These structure contain macula consisting of hair cells and supporting cells.
In light of the above statements, choose thecorrectanswer from the options given below.
Options:
Answer:
Solution:
The vestibular apparatus is composed of three semi-circular canals and the otolith organ consisting of the saccule and utricle. Thus, the vestibule consists of the utriculus and sacculus. Assertion (A) is true.
The saccule and utricle contain a projecting sensory ridge called the macula, which consists of hair cells and supporting cells. Reason (R) is true.
However, the presence of the macula does not explain why the vestibule consists of the utriculus and sacculus. Therefore, both (A) and (R) are true but (R) is not the correct explanation of (A).
Answer: Both (A) and (R) are true but (R) is NOT the correct explanation of (A).
