Nervous System Physiology Questions

Multiple choice

Body functions like cognition, emotions and learning are controlled by

  1. paravertebral ganglia

  2. prevertebral ganglia

  3. basal ganglia

  4. retinal ganglion cell

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The basal ganglia is a group of nuclei interconnected with the cerebral cortex, thalamus and brainstem associated with a variety of functions: motor control, cognition, emotions and learning.

Multiple choice

Pneumotaxic center is present in

  1. cerebrum

  2. cerebellum

  3. medulla oblongata

  4. pons varolli

  5. -
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The pneumotaxic center is a network of neurons in the rostral dorsal lateral pons. It controls the intensity of breathing.

Multiple choice

Which of the following are parts of the peripheral nervous system?

  1. Cranial and spinal nerves

  2. Parietal and occipital lobes

  3. Frontal and temporal lobes

  4. Brain and spinal cord
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The communication between the central nervous system (brain and spinal cord) and other parts of the body is facilitated by peripheral nervous system consisting of cranial nerves arising from the brain and spinal nerves arising from the spinal cord. Thus, our brain allows us to think and take actions.

Multiple choice

Which part of the brain is responsible for a person’s intelligence?

  1. Hypothalamus

  2. Cerebellum

  3. Pons

  4. Cerebrum
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The cerebrum is a major part of the brain, controlling emotions, hearing, vision, personality and intelligence. It also controls all the voluntary actions. The functions of pons include sensory roles in hearing, equilibrium and taste, and in facial sensations such as touch and pain, etc. Hypothalamus is a part of the brain which is important in regulating internal activities like body temperature and release of hormones.

Therefore, the correct answer is ‘cerebrum’.

Multiple choice

Respiratory centre is present in

  1. cerebellum

  2. cerebrum

  3. medulla oblongata

  4. hypothalamus
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The respiratory centres (RCs) are located in the medulla oblongata and pons, which are parts of the brainstem. The RCs receive controlling signals of neural, chemical and hormonal nature and control the rate and depth of respiratory movements of the diaphragm and other respiratory muscles.

Multiple choice

Thermoregulatory centre of human body is associated with

  1. cerebrum

  2. cerebellum

  3. hypothalamus

  4. medulla oblongata
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Thermoregulatory centre is located in the hypothalamus and is concerned mainly with the regulation of heat production, heat inhibition and heat conservation to maintain a normal body temperature.

Multiple choice

Directions: Read the passage and answer the following question.

Which part of the brain controls the involuntary actions?

The nerves, the brain and the spinal cord constitute the nervous system. The nervous system controls and regulates the activities of all the other systems of the body. The brain is the main organ of the nervous system. The brain consists of cerebrum, cerebellum and medulla oblongata. The cerebrum controls voluntary actions and is the seat of intelligence. It is the largest part of the brain. The cerebellum regulates muscular movement of locomotion. The medulla oblongata is the lowermost part of the brain which  continues as the spinal cord in the vertebral column. It controls  involuntary actions. The spinal cord is the elongated nearly cylindrical continuation of medulla oblongata. The spinal cord is the center of various reflex actions. There are several organs in the body that receive the external and internal stimuli and convey it to central nervous system. The main sense organs are for touch, hearing, vision, smell and taste; these are the eyes, skin, tongue, ears, and nose.

  1. Medulla oblongata

  2. Spinal cord

  3. Cerebrum

  4. Cerebellum

  5. None of these
