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.
61
Which statement is true?
RRB NTPC (Stage-I)
02/04/2016 (Shift-I)
2016
✓ Answer:AThe image formed on the retina is inverted
The eye forms a real, inverted retinal image. The source selects A; option C is loosely worded and does not specify image orientation.
62
Thermoregulation in humans is controlled by the _____.
RRB NTPC (Stage-I)
29/04/2016 (Shift-I)
2016
✓ Answer:BHypothalamus
The hypothalamus integrates temperature information and coordinates heat-loss and heat-conservation responses.
63
Which statement about the cerebellum is not true?
RRB Group-D
12/10/2018 (Shift-I)
2018
✓ Answer:CIt is a very small part of the brain, about 25%
The cerebellum accounts for roughly one-tenth of brain mass, not 25%, and helps coordinate movement and balance.
64
Which part of the human brain is the centre of intelligence, memory and emotions?
RRB NTPC (Stage-I)
27/04/2016 (Shift-III)
2016
✓ Answer:BCerebrum
The cerebrum supports higher functions such as intelligence, memory and emotional processing.
65
For how long does the sensation of sound persist in the human brain?
RRB Group-D
12/11/2018 (Shift-II)
2018
✓ Answer:A0.1 s
The conventional school-level value for persistence of hearing used in explaining distinct echoes is approximately 0.1 second.
66
Which part of the brain regulates breathing?
RRB ALP & Technician
31/08/2018 (Shift-I)
2018
✓ Answer:CMedulla
Respiratory centres in the medulla regulate the basic rhythm of breathing, with contributions from other brainstem regions.
67
The function of the lens in our eyes is to:
RRB NTPC (Stage-I)
28/03/2016 (Shift-I)
2016
✓ Answer:CChange the focal distance of the eye
Changes in lens curvature adjust its focal length, helping focus objects at different distances on the retina.
68
I reflexively pulled my hand back from a flame. Which organ is responsible for this action?
RRB Group-D
23/10/2018 (Shift-II)
2018
✓ Answer:BSpinal cord
The withdrawal reflex is integrated in the spinal cord, allowing a rapid protective response.
69
Which structure of the eye refracts light rays and focuses them on the retina?
RRB JE
27/05/2019 (Shift-III)
2019
✓ Answer:CLens
The lens adjusts focus to form a sharp retinal image. The cornea also refracts light and supplies much of the eye's refractive power.
70
Which area of the retina has the highest visual acuity?
RRB JE
29/05/2019 (Shift-II)
2019
✓ Answer:CFovea
The fovea contains densely packed cones and provides the sharpest central vision.
