Test: Sensory Reception & Processing (NCERT) - Question 5

Bony labyrinth is filled with a fluid called

Detailed Solution for Test: Sensory Reception & Processing (NCERT) - Question 5

Internal ear (membranous labyrinth) is surrounded by an almost similar shaped bony labyrinth. The membranous labyrinth is joined to the bony labyrinth at certain points, but its greater part is separated from the bony labyrinth by a narrow perilymphatic space. This space is filled with a watery fluid called perilymph that closely resembles cerebrospinal fluid

Test: Sensory Reception & Processing (NCERT) - Question 6

Eustachian tube is a passage connecting the

Detailed Solution for Test: Sensory Reception & Processing (NCERT) - Question 6

Tympanic cavity (part of middle ear) is an air filled cavity that is connected with the nasopharynx through Eustachian tube. It serves to equalise the air pressure in the tympanic cavity with that on the outside

Test: Sensory Reception & Processing (NCERT) - Question 7

Which of these structures are present on the retina?

Detailed Solution for Test: Sensory Reception & Processing (NCERT) - Question 7
  • The retina is the innermost layer that surrounds the eye.
  • It contains a yellow-pigmented region near its center at the posterior pole of the eye known as the macula lutea.
  • The central pit of the macula lutea is the fovea.
Test: Sensory Reception & Processing (NCERT) - Question 8

In the chemistry of vision in mammals, the photosensitive substance is called

Detailed Solution for Test: Sensory Reception & Processing (NCERT) - Question 8

Rhodopsin is a pigment present in the rod cells of the retina. It consists of two components-opsin and retinal (= retinene). Retinal is an aldehyde of vitamin A which absorbs light falling on the rod and changes its form and separates from the opsin component. This initiates the transmission of a nerve impulse to the brain. Rhodopsin is a photosensitive substance and allows vision in dim light (night vision).

Test: Sensory Reception & Processing (NCERT) - Question 9

Cornea transplant in humans is almost never rejected. This is because

Detailed Solution for Test: Sensory Reception & Processing (NCERT) - Question 9

Cornea is a transparent layer of tissue continuous with sclerotic that forms the front part of vertebrate eye over the iris and lens. It refracts light waves entering the eye onto lens. Cornea is avascular (i.e., has no blood supply). It is one of the first organs to be successfully transplanted because it lacks blood vessels.

Test: Sensory Reception & Processing (NCERT) - Question 10

The black pigment in the eye, which reduces the internal reflection, is located in

Detailed Solution for Test: Sensory Reception & Processing (NCERT) - Question 10

The black pigment, melanin in the eye, which reduces the internal reflection is located in the pigment layer of retina.

Test: Sensory Reception & Processing (NCERT) - Question 11

Identify the structure in the given diagram.

Detailed Solution for Test: Sensory Reception & Processing (NCERT) - Question 11
  • The given diagram is that of the cross section of the eye.
  • The indicated structure is present at the anterior pole of the eye, on the outermost layer called sclera.
  • It is identified to be the cornea.
Test: Sensory Reception & Processing (NCERT) - Question 12

The balancing organ of ear is 

Detailed Solution for Test: Sensory Reception & Processing (NCERT) - Question 12

Semicircular canal, sacculus and utriculus are receptors of equilibrium or balancing organs of ear.

Test: Sensory Reception & Processing (NCERT) - Question 13

The shape of eye lens is changed by

Detailed Solution for Test: Sensory Reception & Processing (NCERT) - Question 13

Ciliary muscles are circular sheet of smooth muscle fibres present within the ciliary body. These muscles alter the shape of the lens during contraction.

Test: Sensory Reception & Processing (NCERT) - Question 14

Protein found in eye lens is

Detailed Solution for Test: Sensory Reception & Processing (NCERT) - Question 14

Proteins found in eye lens are crystallins which are transaprent proteins.

Test: Sensory Reception & Processing (NCERT) - Question 15

Which of the following cells are associated with identification of colours in bright light?

Detailed Solution for Test: Sensory Reception & Processing (NCERT) - Question 15

Cone cells are chiefly concerned with distinction colour and light vision during day time.

Test: Sensory Reception & Processing (NCERT) - Question 16

The size of pupil is controlled by the

Detailed Solution for Test: Sensory Reception & Processing (NCERT) - Question 16

The size of pupil is controlled by two types of muscles of iris, circular muscles and radial muscles. Radial muscles contract in dim light and circular muscles contract in bright light.

Test: Sensory Reception & Processing (NCERT) - Question 17

Cornea is covered externally by a thin transparent membrane which is called

Detailed Solution for Test: Sensory Reception & Processing (NCERT) - Question 17

Cornea is covered externally by a thin transparent membrane called conjunctiva. This membrane helps to protect the eye ball and keeps it moist.

Test: Sensory Reception & Processing (NCERT) - Question 18

The gelatinous membrane covering the sensory hair cells of the ear is known as

Detailed Solution for Test: Sensory Reception & Processing (NCERT) - Question 18

Tectorial membrane is a gelatinous membrane covering the sensory hair cells in the scala media of cochlea.

Test: Sensory Reception & Processing (NCERT) - Question 19

Retina of eye is analogous to which part of camera?

Detailed Solution for Test: Sensory Reception & Processing (NCERT) - Question 19

Retina of our eye is analogous to the light sensitive film of camera.

Test: Sensory Reception & Processing (NCERT) - Question 20

The point in eye of mammals from which optic nerves and blood vessels leave the eye ball is called

Detailed Solution for Test: Sensory Reception & Processing (NCERT) - Question 20

Blind spot lies close to the yellow spot of the eye and lacks receptor cells (rods and cones) because the optic nerves leave the eye ball from here.

Test: Sensory Reception & Processing (NCERT) - Question 21

Internal ear is filled with

Detailed Solution for Test: Sensory Reception & Processing (NCERT) - Question 21

Internal ear consists of two divisions:
(i) bony labyrinth, filled with fluid called perilymph
(ii) membranous labyrinth, filled with fluid called endolymph
