Explanation / Answer

1) The semicircular canals contain endolymph fluid, which contribute to the sensation of equilibrium. When the head moves, then the fluid of the canals move. When the fluid in the canals moves, the hair cells move in the direction of the fluid and produce signals, which detect the changes in the position of the body.

2) Three fluid filled chambers within the cochlea:

The vestibular duct/scala vestibuli - It contains perilymph, which lies superior to the cochlear duct and abuts the oval window

The tympanic duct /scala tympani – It contains perilymph, which lies inferior to the cochlear duct and terminates at the round window.

The cochlear duct / scala media – It contains endolymph, which is a region of high potassium ion concentration that the stereocilia of the hair cells project into helicotrema. Helicotrema is the location where the tympanic duct and the vestibular duct combine at the apex of the cochlea.

3) The correct option is watery eyes.

Red eye, swelling of conjunctiva and watering of the eyes are symptoms all forms of conjunctivitis.
