Question

Receptors concerned with the sense of balance in mammals include the?

• A. Tympanum and cochlea
• B. Tympanum and cristae
• C. Cochlea and cristae
• D. Cristae and maculae

Answer 1

Answer: (A)

Tympanum and cochlea

The balance receptors which are concerned with the sense of balance in mammals includes the cristae ampullaris and maculae. These are located within the vestibular membranous labyrinth of the ear. The macula are located in the utricle and saccule and detect linear acceleration and deceleration, with the with the utricle macule sensing horizontal movements and the saccule detecting vertical movements. The cristae ampullaris is located at the base of the semi-circular canals and thus helping in sensing angular acceleration and deceleration.

So, the correct answer is D.
