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.
81
The term olfactory is related to:
RRB JE
25/05/2019 (Shift-III)
2019
✓ Answer:DSmell
Olfactory refers to the sense of smell.
82
The image formed on the retina of the human eye is:
RRB Group-D
11/10/2018 (Shift-II)
2018
✓ Answer:AReal and inverted
The eye's optical system forms a real, inverted image on the retina.
83
The cell body of a neuron is called:
RRB JE
29/05/2019 (Shift-I)
2019
✓ Answer:DSoma
The source selects soma. Perikaryon is also commonly used for the neuronal cell body, making options A and D overlapping answers.
84
The aperture through which light enters the eye is called the:
RRB JE
02/06/2019 (Shift-III)
2019
✓ Answer:CPupil
The pupil is the opening in the iris; changes in its size regulate entering light.
85
Which statement about the cerebrum is not correct?
The source selects D, intending the cerebellum's role in fine coordination of muscle activity. The wording is broad because the cerebrum also controls voluntary movement.
86
The nature of nerve signalling is:
RRB Group-D
15/11/2018 (Shift-I)
2018
✓ Answer:DElectrochemical
Signals propagate electrically along neurons through ion movements and are commonly transmitted chemically across synapses.
87
Which activities involve voluntary muscles? A. Jumping of a frog; B. Movement of food in the stomach; C. Pumping of the heart; D. Writing by hand.
RRB Group-D
11/10/2018 (Shift-II)
2018
✓ Answer:CA and D
Jumping and writing use skeletal muscles. Gastric movements use smooth muscle, and the heart uses cardiac muscle.
88
The amount of light entering the eye is controlled by the:
RRB Group-D
24/09/2018 (Shift-I)
2018
✓ Answer:APupil
The source selects the pupil. More precisely, iris muscles adjust pupil size, thereby regulating the amount of entering light.
89
How many spinal nerves are there in the human body?
RRB NTPC (Stage-I)
03/04/2021 (Shift-II)
2021
✓ Answer:A31 pairs
Humans have 31 pairs of spinal nerves: 8 cervical, 12 thoracic, 5 lumbar, 5 sacral and 1 coccygeal.
90
The pupil is part of the _____.
RRB JE
25/05/2019 (Shift-III)
2019
✓ Answer:BEye
The pupil is the opening in the centre of the iris of the eye.
