Behavioral Psychology and Physiology Questions

Multiple choice biology coordination in life processes ingestion of food mechanism of digestion

One of the following movements is not completely involuntary. It is

  1. Peristalsis

  2. Systole of ventricles

  3. Dilation of eye pupil

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

Deglutition (swallowing) is a complex process that begins as a voluntary action in the mouth before becoming an involuntary reflex in the pharynx and esophagus.

Multiple choice frog - control and coordination system frog animal diversity - ii (phylum: chordata) organ and organ systems in animals zoology

A frog with crushed brain is pinched on the leg. The leg is drawn away. It is

  1. Automatic motor response

  2. Neurotransmitter induced response

  3. Conditional reflex

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

The withdrawal of a leg in response to a stimulus in a brain-crushed frog is a classic example of a simple reflex, which is mediated by the spinal cord and does not require higher brain centers.

Which of the following is not a type of tactile sensation

  1. Heat

  2. Touch

  3. Vibration

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

Tactile sensations are produced by the pressure receptors in the skin. The tactual sensation is related to touch.


So, the correct option is 'heat'.

Multiple choice biology neural control and coordination structure of muscle skeletal muscles locomotion and movements

Which of the following is called as the response?

  1. Drawing out the hand

  2. Pricking with the pin

  3. Pin in the box

  4. Hand in the pocket
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A stimulus is something that causes a physiological response. The ability of an organism or organ to respond to external stimuli is called sensitivity. So, in the above example, the response to stimulus is drawing out hand and not pricking with pin, only pin or hand.

Therefore, the correct answer is option A.

Multiple choice biology neural control and coordination structure of muscle skeletal muscles locomotion and movements

When you are pricked with a pin, you will draw out your hand very fast. The stimulus is 

  1. Drawing out hand

  2. Pricking with a pin

  3. Pin

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

A stimulus is something that causes a physiological response. The ability of an organism or organ to respond to external stimuli is called sensitivity. So, in the above example, the stimulus is pricking with pin and not drawing out hand, only pin or hand. 

Therefore, the correct answer is option B.

Multiple choice biology neural control and coordination structure of muscle skeletal muscles locomotion and movements

The ability of an organism to respond to external stimuli is called as

  1. Sensitivity

  2. Homeostasis

  3. Metabolism

  4. None of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
  • The stimulus(singular) is any change in the organism's internal or external environment that causes the organism to react.
  • The ability of an organism to respond to external stimuli is called sensitivity. For example, Plants grow towards light(external stimuli) sources, and if the direction of light is changed, the plant will also change its direction of growth to accommodate for survival.
  • So, the correct answer is 'Sensitivity'.
Multiple choice zoology excretion to maintain homeostasis other excretory organ role of other organs in excretion accessory excretory organs excretion in other organisms

Which pair among the following is correct?

  1. Sweat- temperature regulation

  2. Saliva- sense of food taste

  3. Sebum- sexual attraction

  4. Humerus- hind leg
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The sweat on the surface of the skin is evaporated by the body heat. As the water is evaporated by heat released from the body, the body cools off. Each gram of water on the body surface absorbs about 0.58 calories of energy before evaporating, which is a significant source of heat loss.

Which of the following is not a reflex action?

  1. Salivation

  2. Sweating

  3. Withdrawal of hand when pinched by needle

  4. None of these
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

An automatic (involuntary) neuromuscular action excited by a defined stimulus is called reflex action. Sweating is not a reflex action. It is primarily a means of temperature regulation. But, Salivation and hand withdrawal because of the needle both are reflex actions.

  1. Beating of heart

  2. Withdrawing your hand inmediately on touching a hot object

  3. Change in size of pupil in response to intensity of light

  4. Riding a bicycle

The direction of against stimulus response is opposite in which of the following reflex action?

  1. Biceps tendon reflex

  2. Knee jerk reflex

  3. Triceps tendon reflex

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

Option 'D' is correct


Withdrawal reflex is the reflex that involves the withdrawal is response to stimulus. It is also known as pair withdrawal reflex. When pair receptors are stimulated, reciprocal innervation stimulate the flexons to withdrawal and inhibit the extensors.

Which one is not a reflex action?

  1. Closing the eye lids suddenly

  2. Release of saliva

  3. Obeying the order

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

Reflex actions are involuntary and automatic responses to stimuli managed by the nervous system. Closing eyelids, salivation, and pupillary constriction are involuntary reflexes, whereas obeying an order is a voluntary, conscious action.

Which one is correct about voluntary and involuntary movements?

  1. Voluntary movements- caused by skeletal muscle, Involuntary movements- caused by smooth muscle

  2. Voluntary movements- caused by smooth muscle, Involuntary movements- caused by skeletal muscle

  3. Voluntary movements- controlled by brain, Involuntary movements- controlled by organs

  4. Voluntary movements- controlled by organs, Involuntary movements- controlled by brain
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Voluntary movements are movements that are in direct control of the will of a person. These are controlled by skeletal muscles. For example walking, talking, dancing, etc. Involuntary movements are movements that are not in control of a person. They are generated by smooth striated muscle. For example, heart pumping, digestion, etc.
