Free Neural Control And Coordination (Daily Quiz: 3) NEET Biology Questions & Answers with Detailed Explanation & Full Review

Free Neural Control And Coordination (Daily Quiz: 3) Time:

Question-1

Clusters of neuron cell bodies embedded in the white matter of the brain are referred to as

(a)

(b)

(c)

(d)

Explanation:

Answer: (b)

Nuclei are areas of grey matter within the white matter, where nerve impulses are processed.


Question-2

Scala vestibuli is connected with

(a)

(b)

(c)

(d)


Question-3

In which part of the mammalian ear, the nerve impulse for hearing starts?

(a)

(b)

(c)

(d)

Explanation:

Answer: (c)

The cochlea is the hearing or auditory portion of the inner ear. It is a spiral-shaped cavity in the bony labyrinth. The cochlea receives sound in the form of vibrations, which cause the stereocilia to move. The stereocilia then convert these vibrations into nerve impulses which are taken up to the brain to be interpreted. Two of the three fluid sections are canals and the third is a sensitive 'organ of Corti' which detects pressure impulses which travel along the auditory nerve to the brain. The two canals are called the vestibular canal and the tympanic canal.


Question-4

Assertion:
Owl can see at night.
Reason:
They possess a large number of rods and few cones in their retina.

(a)

(b)

(c)

(d)


Question-5

Identify the correct order in which vibrations travel through the auditory ossicles?

(a)

(b)

(c)

(d)

Explanation:

Answer: (a)

The middle ear contains a flexible chain of three middle bones called ear ossicles. The three ear ossicles are malleus, incus, and stapes that are attached to each other. The malleus is attached to tympanic membrane on one side and to incus on the other side. The incus is connected with stapes. Stapes, in turn, are attached with an oval membrane, fenestra ovalis, of internal ear. In ear, vibrations travel through malleus, incus to stapes. The ear ossicles increase the intensity of the sound waves.
