Nervous System Physiology Questions

Multiple choice zoology nervous system of man major divisions of nervous system introduction to control and coordination neurons and synapses

Which part of the brain contains such an area which is neither clearly sensory nor motor in function?

  1. Medulla

  2. Cerebral cortex

  3. Grey matter of cerebrum

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

  • The cerebral cortex of the brain has three regions of function, namely Sensory, motor and association areas. 
  • This association area does not belong either of the primary sensory or motor regions since its function is associative.
  • The main function of these association regions is to provide a perpetual understanding of the world. it helps in effective interaction, abstract thinking, and language. 
  • These association regions are present in the form of an interwoven network.

So the correct option is 'Cerebral cortex'.

In which lobe of the cerebrum are the visual centres located?

  1. Frontal lobe

  2. Parietal lobe

  3. Temporal love

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

The visual system is the part of the central nervous system which gives organisms the ability to process visual detail as sight, as well as enabling the formation of several non-image photo response functions. In cerebrum, the visual centres are located on the occipital lobe.

So, the correct option is 'Occipetal lobe'.

Multiple choice

Which part of the brain regulates sleep?

  1. Forebrain

  2. Midbrain

  3. Hindbrain

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

The forebrain, specifically areas like the hypothalamus, plays a critical role in regulating circadian rhythms and sleep cycles.

Multiple choice

What is the Brain?

  1. A bone

  2. A thing

  3. A organ

  4. Nothing
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The brain is an organ - the most complex organ in the human body, composed of specialized nervous tissue. It is not a bone (those are part of the skeletal system), 'a thing' is too vague, and it is certainly not 'nothing' - it's the seat of consciousness and controls all bodily functions.

Multiple choice

What protects your brain

  1. cerebrospinal fluid and your skull

  2. your skull only

  3. a helmet only
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The brain is protected by the hard structure of the skull and cushioned by cerebrospinal fluid, which absorbs shock.

Multiple choice

What part of the brain creates imagination?

  1. Archicortex

  2. Allocortex

  3. Paleocortex

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

The neocortex is the part of the mammalian brain involved in higher-order brain functions such as sensory perception, cognition, generation of motor commands, spatial reasoning, and language, which are essential for imagination.

Which part of the human brain controls balance, posture and coordination?

  1. Cerebrum

  2. Cerebellum

  3. Medulla oblongata

  4. Thalamus

  5. Hypothalamus
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The cerebellum is a small region at the back of the brain. It is the largest part of hind brain. The cerebellum controls smooth, coordinated movements, helps to maintain muscle tone, posture, and balance.

Multiple choice zoology nervous system of man parts of the brain brain and its parts brain

The brainstem is made up of

  1. Midbrain, Pons, Cerebellum

  2. Midbrain, Pons, Medulla oblongata

  3. Forebrain, Pons, Cerebellum

  4. Cerebellum, Cerebrum, Medulla oblongata
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The region of the brain that connects the cerebrum to the spinal cord is called as brainstem. It is made up of midbrain, medulla oblongata and pons. It is a site where many cranial nerves are located. The brainstem is involved in te relay of signals between the spinal cord and brain. It also controls the working of the PNS. Thus the correct answer is option B.

Match the columns

A) Hypothalamus 1) intersensory associations
B) Limbic lobe 2) expression of emotional reactions
C) Medulla  3) urge of eating and drinking 
D) Association areas 4) gastric secretion reflex
  1. $A-2,B-3,C-4,D-1$
  2. $A-3,B-2,C-4,D-1$
  3. $A-3,B-1,C-4,D-2$
  4. $A-2,B-1,C-4,D-3$
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The limbic system is basic to motivation, emotion, and reward processes. It controls emotional expression through the hypothalamus, which has control over the body's emotional responses systems. The thalamus in the limbic system (' leopard brain') signals the brain thus we get to feel satisfaction for each mouthful of food. The acid and semi-digested fats in the duodenum trigger the enterogastricreflex – the duodenum sends inhibitory signals to the stomach by way of the enteric nervous system, and sends signals to the medulla that inhibit the vagal nuclei, thus reducing vagal stimulation of the stomach. Association cortex is the cerebral cortex outside the primary areas. It is essential for mental functions that are more complex than detecting basic dimensions of sensory stimulation, for which primary sensory areas appear to be necessary. So the correct option is 'A−2,B−3,C−4,D−1'.

Dendrites are a part of 

  1. Grey matter

  2. White matter

  3. Dura mater

  4. Arachnoid mater
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Dendrites are the branched projections of a neuron that receive signals. They are located in the grey matter of the central nervous system, which consists primarily of neuronal cell bodies and dendrites.

Multiple choice biology nervous system of man structure and function of spinal cord the spinal cord spinal cord

Choose the correct answer from the alternatives given.
Which of the following structures or regions is incorrectly paired with its function?

  1. Brocas regions-screening of information between the spinal cord and the brain regulates arousal and sleep

  2. Medulla oblongata - homeostatic control centres

  3. Cerebellum - unconscious co-ordination of movement and balance

  4. Hypothalamus - production of hormones and regulation of temperature, hunger, and thirst
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Broca's area is a region in the frontal lobe of the dominant hemisphere, usually the left, of the brain with functions linked to speech production.

So, the correct option is 'Broca's region - Screening of information between the spinal cord and the brain regulates arousal and sleep'.

Multiple choice zoology neural control and coordination structure and function of spinal cord the spinal cord spinal cord

The "butterfly " like structure surrounding the central region of human's spinal cord is called as

  1. Funiculus

  2. Horn

  3. White matter

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

The grey matter, in the center of the spinal cord, is shaped like a butterfly and consists of cell bodies of interneurons and motor neurons, as well as neuroglia cells and unmyelinated axons. Projections of the grey matter (wings) are called as horns. Together, the grey horns and the grey commissure form the "grey H."

Waves emitted in brain during deep sleep is

  1. Alpha

  2. Beta

  3. Delta

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

A delta wave is a high amplitude brain wave. Delta waves are usually associated with the deep stage 3 of NREM sleep, also known as slow-wave sleep (SWS) and aid in characterizing the depth of sleep.
