Weekly Quiz Competition

Question 1
1 / -0

Read the following about the surface of cerebral hemispheres

i. Is made up of the pia matter.
ii. Is greatly convoluted and called the cerebral cortex.

A
Statement i) is wrong and ii) is correct.

B
Statement i) is correct and ii) is wrong.

C
both are correct

D
both are wrong

Solution

The layer of cells which covers the cerebral hemisphere is called cerebral cortex and is thrown into prominent folds.
Question 2
1 / -0

The autonomic nervous system or ANS :

i. Is truly autonomic i.e. independent of the CNS.
ii. Is also known as the VNS.
iii. Transmit impulse from CNS to involuntary organs and smooth muscles.

A
only i) and iii) are correct.

B
only ii) and iii) are correct.

C
only iii) is correct.

D
all are correct.

Solution

The autonomic nervous system or ANS is the division of peripheral nervous system that influences the function of internal organs. ANS is also known as VNS. These nerves transmit impulse from CNS to involuntary organs and smooth muscles.
Question 3
1 / -0

The band of nerve fibers that joins the two cerebral hemisphere in mammals is :

A
corpus callosum

B
corpora quadrigemina

C
cruracerebri

D
corpora bigemina

Solution

The corpus callosum (CC) is the largest of the commissural fibres, linking the cerebral cortex of the left and right cerebral hemisphere.
Question 4
1 / -0

Vermis is a portion of :

A
Medulla oblongata

B
Cerebellum

C
Cerebrum

D
Pons

Solution

Cerebral vermis is located in the medial, cortico-nuclear zone of the cerebellum. It is constricted between lobe of cerebellum.
Question 5
1 / -0

Part of brain that acts as relay centre to receive and transmit general sensations except smell :

A
Epithalamus

B
Hypothalamus

C
Midbrain

D
Thalamus

Solution

Thalamus is the part of brain that acts as relay centre to receiveand transmit general sensations except smell. Thalamus is located in the forebrain superior to the midbrain.
Question 6
1 / -0

Brain cavities are filled with CSF. In subarachnoid space, the CSF plays following roles :

A
changes pressure inside cranium in coordination with blood pressure

B
Plays a role in night vision

C
keeps brain and spinal cord dry to prevent infection

D
acts as a shock proof cushion

Solution

Brain cavities are filled with cerebrospinal fluid (CSF). In subarachnoid space, the CSF acts as shock proof cushion to prevent in injury in case of accident.

Question 7

1 / -0

In Pavlov’s conditioned reflex experiment find the correct matches :

Column A	Column B
a) conditioned stimulus	i) salivation in response to food
b) conditioned response	ii) food itself
c) unconditioned stimulus	iii)sound of the bell
d) unconditioned response	iv) salivation in response to bell

a)-ii, b)-iii, c)-i, d)-iv

a)-iii, b)-iv, c)-ii, d)-i

a)-i, b)-iii, c)-iv, d)-ii

a)-iv, b)-ii, c)-i, d)-iii

Solution

There are different kinds of stimulus that is received by different receptors in our body. Hearing of sound of bell is conditioned stimulus and salivation in response to bell is conditioned response. Food itself is conditioned stimulus and salivation in response to food is unconditioned response.

Question 8
1 / -0

A region on retina of human eye which is free from rods and cones is :

A
optic nerves

B
fovea

C
yellow spot

D
black spot

Solution

The optic nerves leave the eye and the retinal blood vessels enter it at a point medial to and slightly above the posterior pole of the eye ball. Photoreceptor cells are not present in that region and hence it is called the blind spot.
