Question 1
1 / -0

Where are relay neurons situated?

A
Effector

B
Spinal cord

C
Spinal nerve

D
Receptor

Solution

Relay neurons are found between sensory input and motor output/response. Relay neurons are found in the brain and spinal cord and allow sensory and motor neurons to communicate. Motor neurons are found in the central nervous system (CNS) and control muscle movements.
Hence the correct option is B.
Question 2
1 / -0

Anosmia is _____

A
Loss of the sense of taste

B
Loss of the sense of smell

C
Loss of the sense of sound

D
Loss of the sense of touch

Solution

The following are disorders of olfaction: Anosmia inability to smell. ysosmia things smell different from memory or expectation. Hyperosmia an abnormally acute sense of smell. Hyposmia decreased ability to smell.
Question 3
1 / -0

What are the two types of cells in nervous system?

A
Alveoli and veins

B
Alveoli and bronchioles

C
Neurons and nephrons

D
Neurons and glia

Solution

The nervous system is made up of neurons - specialized cells that can receive and transmit chemical or electrical signals and glia - cells that provide support for the neurons. A neuron can be compared to an electrical wire. It transmits a signal from one place to another.
Glia can be compared to the workers at the electric company who make sure wires go to the right places, maintain the wires, and take down wires that are broken.
Alveoli and bronchioles are the part of the respiratory system, nephrons is a part of the excretory system.
Hence the correct option is D.
Question 4
1 / -0

Which of the following functions is influenced by autonomic nervous system?

A
Heart rate

B
Digestion

C
Urination

D
All of the above
Solution
- The autonomic nervous system is a control system that acts largely unconsciously and regulates bodily functions such as the heart rate, digestion, respiratory rate, pupillary response, urination, and sexual arousal. Hence, Heart rate, Digestion and Urination functions are influenced by the autonomic nervous system.
So, the correct answer is 'All of the above'.
Question 5
1 / -0

How many pairs of sympathetics ganglia are present in ANS?

A
$$10$$

B
$$12$$

C
$$22$$

D
$$31$$

Solution

There are 22 pairs of paravertebral sympathetic ganglia on either side of the vertebral column as well as prevertebral ganglia in the abdomen and pelvis and additionally intermediate ganglia.
Question 6
1 / -0

Which of the following is/are true?

A
the inner ear consists of a cochlea, the semicircular canals and the auditory nerve

B
the middle ear is an air filled cavity that consists of an ear drum and three tiny interconnected bones the hammer, anvil and stirrup

C
the human ear consists of three basic parts - outer ear, middle ear and inner ear

D
all of these

Solution

All of the options are correct.
The inner ear consists of a cochlea, the semicircular canals and the auditory nerve.
The middle ear is an air filled cavity that consists of an ear drum and three tiny interconnected bones the hammer, anvil and stirrup.
The human ear consists of three basic parts - outer ear, middle ear and inner ear.
Question 7
1 / -0

Where does the motor neurons of the autonomic nervous system exist?

A
Posterior vagal trunks

B
Autonomic ganglia

C
Vagus nerves

D
Thoracic nerves
Solution
- Autonomic ganglia are clusters of neuronal cell bodies and their dendrites.
- They are essentially a junction between autonomic nerves originating from the central nervous system and autonomic nerves(motor and sensory nerves) innervating their target organs in the periphery. Hence, the motor neurons of the autonomic nervous system exist at Autonomic ganglia.
Question 8
1 / -0

How many pairs of cervical nerves are there in a human body?

A
1

B
8

C
12

D
5

Solution

There are eight pairs of cervical nerves, twelve pairs of thoracic nerves, five pairs of lumbar nerves, five pairs of sacral nerves, and one pair of coccygeal nerves. Therefore, the correct answer is option B.
Question 9
1 / -0

Which of the following is regulated by autonomic nervous system?

A
Heart

B
Internal organs

C
Brain

D
External organs
Solution
- The autonomic nervous system is a control system that acts largely unconsciously and regulates bodily functions such as the heart rate, digestion, respiratory rate, pupillary response, urination, and sexual arousal. Hence, Internal organs are regulated by the autonomic nervous system.
So, the correct answer is 'Internal organs'.
Question 10
1 / -0

Above the uppermost concha, is the

A
Vestibule

B
Olfactory bulb

C
Conchae

D
Turbinates

Solution

Above the uppermost concha, is the olfactory bulb. It processes information about odours.
The entire nasal cavity is lined by a moist mucous membrane supplied with a large number of blood vessels.
The mucous membrane also has fine hair-like projections called the cilia which collect any debris entering the nasal cavity.
Apart from the cilia, the mucous membrane also has several cells. Some of these cells are called as secretory cells. Secretory cells secrete a thick, viscous fluid called as the mucous.
