a) Macula lutea
b) Cornea
c) Retina
d) Blind spot
View Answer
Explanation: Macula lutea is small yellowish area of retina. It provides central vision.
5. Which part is a colorful part of the eye?
a) Pupil
b) Iris
c) Eyeballs
d) Cornea
View Answer
Explanation: Iris is a thin circular structure of the eye. It is responsible for controlling the diameter and size of the pupil.
6. Aqueous humour and vitreous humor are divided by ___________
a) Lens
b) Iris
c) Retina
d) Optic nerve
View Answer
Explanation: The lens is a transparent biconvex structure in the eye. It helps to refract light to be focused on the retina.
7. Internal ear is filled with _________
a) Perilymph
b) Endolymph
c) Lymph
d) Mesolymph
View Answer
Explanation: Endolymph is the fluid contained in the membranous labyrinth of the inner ear. It is also called as Scarpa’s fluid.
8. Eustachian tube is present between _________
a) Middle ear and larynx
b) Outer ear and pharynx
c) Middle ear and pharynx
d) Inner ear and larynx
View Answer
Explanation: Eustachian tube is also known as auditory tube. It is approx 35mm long and 3mm in diameter.
9. Sequence of ear ossicles from outside to inside is ____________
a) Malleus incus stapes
b) Incus stapes Malleus
c) Stapes incus malleus
d) Malleus stapes incus
View Answer
Explanation: Ear ossicles are three bones in middle ear. They are the smallest bones in humans. The term ossicle means tiny bones.
10. Which of the following is balancing organ?
a) Organ of corti
b) Cochlea
c) Vestibular region
d) Eardrum
View Answer
Explanation: Vestibule is the central art of inner ear and is situated medial to eardrum behind cochlea. It contains organ of hearing (cochlea) and organ of balance (labyrinth).
11. What separates the outer ear from the middle ear?
a) Auricle
b) Ear wall
c) Cochlea
d) Ear drum
View Answer
Explanation: Eardrum is a thin cone-shaped membrane. It separates the external ear from the middle ear. It is also called a tympanic membrane.
12. Which part of the ear takes sound waves and turns them into vibrations?
a) Middle war
b) Ear wall
c) Ear canal
d) Inner ear
View Answer
Explanation: Middle war contains 3 bones. These 3 bones form a connection from the eardrum to the inner ear. As sound waves hit the eardrum, the eardrum moves back and forth causing the ossicles to move.
