Answer 1

B. False

The ear ossicles transmit vibration through oval window, not round window.

C. False.

Astigmatism is a condition in which the curvature of eye lens is irregular, not the curvature of retina. The retina remain normal.

D. True

The 6 extraocular muscles are superior rectus, inferior rectus, lateral rectus, medial rectus, superior oblique and inferior oblique.

E. False.

Visceral sense is perception of internal organs. Smell and taste do not come under internal organs sensation.

Accomodation refers to change in curvature of lens to focus clearly near object as well as far object (not just near vision).

In accomodation, the lens changes its focal length with the help of ciliary muscles.
