Practice Nervous System RRB PYQ questions asked in various Railway Recruitment Board examinations. This page provides important previous year questions from the Nervous System chapter along with correct answers and clear explanations to help you prepare effectively for RRB Biology.
The Nervous System is an important Biology topic covering the brain, spinal cord, nerves, neurons and coordination of body activities. Questions can focus on the structure and functions of different parts of the nervous system and how nerve impulses help control and coordinate various activities of the body.
31
Which part allows light to enter the human eye?
RRB NTPC (Stage-I)
02/03/2021 (Shift-II)
2021
✓ Answer:CCornea
The source selects the cornea, the transparent front surface through which light first enters. The wording is ambiguous because light also passes through the pupil.
32
An EEG (electroencephalogram) is used to investigate disorders of which organ?
RRB NTPC (Stage-I)
31/07/2021 (Shift-I)
2021
✓ Answer:ABrain
An EEG records electrical activity in the brain through electrodes placed on the scalp.
33
Which is the main thinking part of the human brain?
RRB ALP & Technician
10/08/2018 (Shift-II)
2018
✓ Answer:DForebrain
The cerebrum within the forebrain is the principal centre for conscious thought and higher mental functions.
34
In which body part are the cornea and retina found?
RRB JE
24/05/2019 (Shift-III)
2019
✓ Answer:BEye
The cornea is the transparent front surface of the eye and the retina is its light-sensitive inner layer.
35
Which structure contains nerve fibres that transmit impulses to and from the brain and mediates reflex actions?
RRB NTPC (Stage-I)
30/12/2020 (Shift-I)
2020
✓ Answer:DSpinal cord
The spinal cord carries ascending and descending signals and integrates many reflexes.
36
Which structure contains the thermostat of the human body?
RRB SSE
21/12/2014
2014
✓ Answer:DHypothalamus
The hypothalamus coordinates responses that maintain body temperature.
37
On which principle does the human eye work?
RRB JE
01/06/2019 (Shift-I)
2019
✓ Answer:CRefraction of light
The cornea and lens refract incoming light to form an image on the retina.
38
Which of these is associated with colour vision?
RRB JE
26/05/2019 (Shift-III)
2019
✓ Answer:CCones
Cone photoreceptors in the retina support colour vision and detailed vision in bright light.
39
What is the cyton also called?
RRB Group-D
15/10/2018 (Shift-I)
2018
✓ Answer:APerikaryon cell
The cyton is the neuron's cell body, also called the soma or perikaryon.
40
What is the ability of the human eye to adapt for seeing near and distant objects called?
RRB NTPC (Stage-I)
30/03/2016 (Shift-II)
2016
✓ Answer:BAccommodation
Accommodation is adjustment of the lens's curvature and focal length to focus at different distances.
