• C. A- 5, B- 4, C- 3, D- 2, E- 1

Answer 1

The correct option is D A- 3, B- 1, C- 5, D- 2, E- 4

The membranous labyrinth is found in the inner ear of humans. It is lined with epithelium cells and filled with endolymph.

Weberian ossicles are structures found in bony fish (teleosts). These ossicles form a link between the inner-ear region and the swimbladder which facilitates sound reception.

The organ of Corti is the receptor organ for hearing and is located in the mammalian cochlea.

Fenestra ovalis or oval window is a membrane-covered opening that is present at the intersection of the inner ear and middle ear and is directly in contact with the stapedial plate.

The function of the crista ampullaris is to sense angular acceleration and deceleration.

Thus, the correct answer is option D.
