Weekly Quiz Competition

Question 1
1 / -0

Nissl’s granules are absent in :

A
perikaryon

B
cyton

C
axon

D
dendrite

Solution

Explanation:

Nissl’s grains are mainly present in cyton and dendrite. These granules are rough endoplasmic reticulum with rosettes of free ribosome, the site for protein synthesis. It is absent in axon.
Question 2
1 / -0

Vermis is a portion of :

A
Cerebellum

B
Medulla oblongata

C
Cerebrum

D
Pons

Solution

Explanation:

Cerebral vermis is located in the medial, cortico-nuclear zone of the cerebellum. It is constricted between lobe of cerebellum.
Question 3
1 / -0

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

A
cruracerebri

B
corpus callosum

C
corpora bigemina

D
corpora quadrigemina

Solution

Explanation:

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

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 iii) is correct.

C
only ii) and iii) are correct.

D
all are correct.

Solution

Explanation:

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 5
1 / -0

Brain stem is the support system of brain and is the collective name for :

A
prosencephalon,mesencephalon,pons and medulla

B
cerebrum,mesencephalon,diencephalon and medulla

C
medulla,pons,midbrain and diencephalon

D
hypothalamus,diencephalon,cerebellum and pons

Solution

Explanation:

The brainstem (or brain stem) is the posterior part of the brain, adjoining and structurally continuous with the spinal cord. In the human brain the brainstem includes the midbrain, the pons, and the medulla oblongata. Sometimes the diencephalon, the caudal part of the forebrain, is included.
Question 6
1 / -0

Hypothalamus helps to maintain homeostasis by controlling hunger, thirst, blood pressure, temperature feelings etc. So it is an important link between

A
nervous system and digestive system

B
nervous system and circulatory system

C
nervous system and respiratory system

D
nervous system and endocrine system

Solution

Explanation:

One of the most important functions of the hypothalamus is to link the nervous system to the endocrine system via the pituitary gland (hypophysis). The hypothalamus is located below the thalamus and is part of the limbic system
Question 7
1 / -0

In the prosencephalon, first and second ventricles open into third ventricle by :

A
foramen of Ovale

B
foramen of Magnum

C
foramen of Magnidae

D
foramen of Monro

Solution

Explanation:

In prosencephlon, the first and second ventricles open into third ventricles by foramen of Monro. It is the opening that connects the left and right sides of lateral ventricle in brain.
Question 8
1 / -0

The property which doesn’t belong to nerve fibres is :

A
only elasticity

B
conductivity and excitability

C
only contractility

D
Both elasticity and contractility

Solution

Explanation:

Nerve fibres are specialized to transmit impulses form one part of the body to other. Nerve fibres do not shows the property of elasticity and contractility.
