Nervous System Physiology Questions

Multiple choice biology nervous system of man divisions of nervous system autonomic nervous system the human brain

Premotor area of brain is the highest centre of

  1. Thinking

  2. Autonomous nervous system

  3. Movements of involuntary muscles

  4. Both B and C
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The premotor area occurs in the frontal lobe of the cerebrum. It is made up of the neurons that form the part of the autonomous nervous system and movements of the involuntary muscles like movements of pharynx and larynx. The prefrontal cortex of the frontal lobe is concerned with thinking and reasoning.

Hence, the correct answer is 'Both B and C'

Multiple choice zoology nervous system nervous systems involved in emotions types of nervous system components of nervous system

Centre of autonomic nervous system is located in

  1. Hypothalamus

  2. Medulla oblongata

  3. Cerebellum

  4. Both A and B
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
  • Autonomous system the part of the nervous system responsible for the control of the bodily functions not consciously directed, such as breathing, the heartbeat, and digestive processes.
  • Centre of the autonomic nervous system is located in Hypothalamus and Medulla oblongata.
  • So, the correct answer is 'Both A and B'.
Multiple choice biology structure and functions of living organisms -ii nervous system in animals structure of neuron structure and function of neuron role of receptors in the mouth types of teeth circulatory system and organs

The organ that helps us to recall and analyse is 

  1. Muscles

  2. Brain

  3. Spinal cord

  4. Nerve
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The brain regulates an array of functions necessary for survival. The brain houses our mind and our memories. Most available evidence suggests that the functions of memory are carried out by the hippocampus and other related structures in the temporal lobe of the brain. The brain also helps in the analysis of various body functions.

So, the correct answer is 'Brain'.

Multiple choice biology plant and animal tissues nervous system in animals structure of neuron structure and function of neuron

Choose the correct answer from the alternatives given.
Grey matter is

  1. located on the outside of the spinal cord

  2. restricted to the brain

  3. populated by cell bodies of neurons

  4. found in the ventricles of the vertebrate brain
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Grey matter is a major component of the central nervous system, consisting of neuronal cell bodies, neuropil, glial cells, synapses, and capillaries.

So, the correct option is 'populated by cell bodies of neurons'.

Vomiting is controlled by

  1. Medulla oblongata

  2. Pons vorolli

  3. Diencephalon

  4. Corpus collosum
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The medulla oblongata is the part of the brainstem that controls involuntary functions, including the vomiting reflex.

Correct the following statements by replacing the terms underlined (wherever necessary) and select the correct option.
(i) The part of human brain which regulates heart beat is called cerebrum.
(ii) Chemotropism is directional movement.
(iii) The centre for sexual behaviour is situated in medulla oblongata.
(iv) The plant hormone named after the fungus causing bakane disease is IAA.
(v) Centre for hunger and thirst is located in diencephalon.

  1. (i) Hypothalamus (ii) Tropic (iii) Cerebrum (iv) Auxin (v) Diencephalon

  2. (i) Medulla oblongata (ii) Directional (iii) Hypothalamus (iv) Gibberellin (v) Diencephalon

  3. (i) Hypothalamus (ii) Tropic (iii) Cerebrum (iv) Auxin (v) Metencephalon

  4. (i) Medulla oblongata (ii) Directional (iii) Hypothalamus (iv) Gibberellin (v) Metencephalon
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Medulla oblongata: This section of the brain helps transfer messages to the spinal cord and the thalamus in the brain from the body and controls breathing, heart function, blood vessel function, digestion, sneezing, and swallowing. Sensory and motor neurons from the forebrain and midbrain travel through the medulla.The hypothalamus is a section of the brain responsible for hormone production. The hormones produced by this area of the brain govern body temperature, thirst, hunger, sleep, circadian rhythm, moods, sex drive, and the release of other hormones in the body.
The cerebrum or cortex is the largest part of the human brain, associated with higher brain function such as thought and action. The cerebral cortex is divided into four sections, called "lobes": the frontal lobe, parietal lobe, occipital lobe, and temporal lobe.
The diencephalon is the region of the embryonic vertebrate neural tube that gives rise to posterior forebrain structures including the thalamus, hypothalamus, posterior portion of the pituitary gland, and pineal gland.
Chemo-tropism is the growth of organisms (or parts of an organism, including individual cells) such as bacteria and plants, navigated by chemical stimulus from outside of the organism or organisms part. The response of the organism or organism part is termed positive if the growth is towards the stimulus or negative if the growth is away from the stimulus.
An example of chemo-tropic movement can be seen during the growth of the pollen tube, where growth is always towards the ovules. It can be also written that conversion of flower into fruit is the example of chemo-tropism.

Multiple choice zoology control and coordination in living organisms control of blood glucose endocrine system and hormone hormones in human reproduction testes and ovary parts of the brain kidney

Which part of the brain regulates the body temperature, hunger and water balance?

  1. Hypothalamus

  2. Infundibulum

  3. Medulla oblongata

  4. Pons veroli
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The hypothalamus is a mass of grey matter present at the base of the cerebrum. The centre for thirst and drinking regulation is present in lateral hypothalamus while that for hunger and satiety is present in the arcuate nucleus, ventral nucleus and lateral hypothalamic area. The anterior hypothalamic region regulates body temperature.

So, the correct answer is option A.

Multiple choice zoology control and coordination in living organisms control of blood glucose endocrine system and hormone hormones in human reproduction testes and ovary parts of the brain kidney

Which part of brain is supposed to be damaged if in an accident, a person lose control of water balance, hunger and body temperature?

  1. Cerebellum

  2. Hypothalamus

  3. Medula oblongata

  4. Corpora quadrigemina
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The hypothalamus is the control centre for many autonomic functions of the peripheral nervous system. Connections with structures of the endocrine and nervous systems enable the hypothalamus to play a vital role in maintaining homeostasis. The hormones produced by this area of the brain govern body temperature, thirst, hunger, sleep, circadian rhythm, moods, sex drive, and the release of other hormones in the body. Hence, if hypothalamus is damaged in an accident, control of water balance, hunger and body temperature will be lost.
