A
Multipolar neurons

B
Bipolar neurons

C
Unipolar neurons

D
Non-polar neurons

Bipolar neurons have one axon and one dendrite and are present in the retina of eye.
Question 3
1 / -0

Which of the following is the tough fibrous outermost membrane that adheres closely to the inside of the skull?

A
Piamater

B
Arachnoid membrane

C
Duramater

D
Fontanel

Solution

Duramater is the tough fibrous outermost membrane that adheres closely to the inside of the skull.
Question 4
1 / -0

Consider the following statements and choose the correct option accordingly:

a. Hind brain consists of cerebellum, pons varolli, and medulla oblongata.
b. The frontal lobe is separated from the occipital lobe by the lateral sulcus.

A
Both the statements are true.

B
Both the statements are false.

C
Statement 'b' is true and statement 'a' is false.

D
Statement 'a' is true and statement 'b' is false.

Solution

As statement 'b' is false. The lateral sulcus divides both the frontal lobe and parietal lobe above from the temporal lobe below. The parietal lobe is separated from the occipital lobe by the parieto-occipital sulcus.
Question 5
1 / -0

In the cerebrum, which of the following areas lies in the temporal lobe below the lateral sulcus?

A
Auditory area

B
Sensory speech area

C
Pre central area

D
Postcentral area

Solution

The auditory area lies in the temporal lobe below the lateral sulcus and is the centre for hearing.
Question 6
1 / -0

Which of the following lobes of the cerebral hemisphere performs the function of decoding and interpretation of visual information, shape and colour?

A
Temporal lobe

B
Parietal lobe

C
Occipital lobe

D
Frontal lobe

Solution

Occipital lobe of the cerebral hemisphere performs the function of decoding and interpretation of visual information, shape and colour.
Question 7
1 / -0

The function of which of the following is to receive and integrate signals from spinal cord and further send the resulting signals to the cerebellum and thalamus?

A
Medulla oblongata

B
Cerebral peduncles

C
Pons varolii

D
Cerebellum

Solution

The function of medulla oblongata is to receive and integrate signals from spinal cord and further send the resulting signals to the cerebellum and thalamus.
Question 8
1 / -0

The shape of which of the following components of the limbic system roughly resembles the sea horse and is located inside the temporal lobe?

A
Amygdala

B
Hippocampus

C
Septal nuclei

D
Mamillary bodies

Solution

The shape of hippocampus of the limbic system roughly resembles the sea horse and is located inside the temporal lobe.
Question 9
1 / -0

Which of the following is the largest cranial nerve, arises from the ventral surface of pons varolii and divides into ophthalmic, maxillary and mandibular nerves?

A
Olfactory nerve

B
Trochlear nerve

C
Abducens nerve

D
Trigeminal nerve

Solution

Trigeminal nerve is the largest cranial nerve, arises from the ventral surface of pons varolii and bears a trigeminal ganglion at its origin. It divides into ophthalmic, maxillary and mandibular nerves.
Question 10
1 / -0

Which of the following are the axons of the neurons that are present in the parasympathetic ganglia and innervate the smooth muscles and glands of the viscera?

A
Sympathetic chains

B
Postganglionic fibres

C
Collateral ganglia

D
Preganglionic fibres

Solution

Postganglionic fibres are the axons of the neurons that are present in the parasympathetic ganglia and innervate the smooth muscles and glands of the viscera.
Question 11
1 / -0

Consider the following statements and choose the correct answer.

a. In man, impulses can be transmitted at a maximum speed of about 130 metres per second by nerve fibres.
b. The continuity between the presynaptic and postsynaptic neurons is provided by the gap junction.

A
Both the statements are true.

B
Both the statements are false.

C
Statement 'a' is false and statement 'b' is true.

D
Statement 'b' is false and statement 'a' is true.

Solution

This is the correct option as both the statements are true. In man, impulses can be transmitted at a maximum speed of about 130 metres per second by nerve fibres. The continuity between the presynaptic and postsynaptic neurons is provided by the gap junction.
Question 12
1 / -0

Which of the following diseases of the neural system is an acute viral infection in which the cell bodies of motor neurons in the anterior horn of the spinal cord are destroyed?

A
Neuritis

B
Parkinson's disease

C
Poliomyelitis

D
Schizophrenia

Solution

Poliomyelitis is an acute viral infection in which the cell bodies of motor neurons in the anterior horn of the spinal cord are destroyed. The major symptoms of this disease are fever, sore throat, headache, vomiting and fatigue.
Question 13
1 / -0

Receptors receive stimuli and pass impulse to nervous system. Which of the following receptors is a mechanoreceptor that responds to touch and pressure?

A
Tangoreceptor

B
Caloreceptor

C
Gustatoreceptor

D
Frigidoreceptor

Solution

Tangoreceptor is a mechanoreceptor that responds to touch and pressure. Merkel's disc is an example.
Question 14
1 / -0

Which of the following is an air-filled, membrane-lined space located between the ear canal and the Eustachian tube, cochlea and auditory nerve?

A
Tympanic cavity

B
External auditory meatus

C
Tympanic membrane

D
Pinna

Solution

Tympanic cavity is an air-filled, membrane-lined space located between the ear canal and the Eustachian tube, cochlea and auditory nerve.

A
Vitreous humour

B
Aqueous humour

C
Lens

D
Retina

Solution

Aqueous humour helps in maintaining the shape of the front part of the eye and provides nutrients to the cornea. It also produces pressure in the eye.
