Multiple choice zoology control and coordination in living organisms the reflex action reflex action and reflex arc basic reflex action and reflex arc

All movements in response to the environment can be carefully controlled.

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Each kind of a change in the environment evokes an appropriate movement in response. When we want to talk to our friends in class, we whisper, rather than shouting loudly. So, the movement to be made depends on the event triggering it. Hence, such controlled movement must be connected to the recognition of various events in the environment, followed by only the correct movement in response. Therefore, the correct answer is option A.

Which of the following statements are true about reflex action?
i. It is a response activated after the activity or incident completes.
ii. It is an involuntary action.
iii. It is the sudden action in response to something in the environment.
iv. Impulse is carried to the brain directly for the response.

  1. (ii) and (iii)

  2. (ii) and (iv)

  3. Both A and B

  4. None of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Reflex action is an action which is given in response to something in the environment. It is an immediate action taken without much thinking and it does not have our control. The spinal cord is responsible for the response of the body because the impulse has not reached the brain till then. Therefore, the correct answer is option A.

Closing both the eyes when a torch light is flashed on one eye is a part of 

  1. Reflex action

  2. Chemotropism

  3. Hormonal control

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

  • The best-known reflex is the pupillary light reflex. If a light is flashed near one eye, the pupils of both eyes contract.
  •  Light is the stimulus, impulses reach the brain via the optic nerve, and the response is conveyed to the pupillary musculature by autonomic nerves. 

Therefore, the correct answer is option A.

Which of the following actions are reflex actions?


1.Movement of the diaphragm during respiration
2.Coughing
3.Yawning
4.Sneezing
5.Removal of hand on being touched by hot object

  1. A. II and v only

  2. B. III,IV and V only

  3. C. IV and V only

  4. D. I,II,III,IV and V
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Reflex action is an involuntary action and it is a sudden reaction against the stimulus. e.g. removal of hand on being touched by hot or insertion of a pin in a skin, coughing, closing of the eyelid when any object enters in the eye

But Movement of the diaphragm during respiration is due to movement of Ribs muscles and Yawning and sneezing are involuntary actions not reflex actions.
So, the correct answer is 'Coughing and removal of hand on being touched by hot object'

A Correct answer
Explanation

  • The movement of animals towards or away from the stimulus is called as the taxis. The taxis may be negative or positive. 
  • The movement away from a stimulus is called negative taxis and the movement towards the stimulus is called positive taxis.


Therefore, the correct answer is option A.

Multiple choice biology life processes: control and coordination feedback mechanism mechanism of hormone action and feedback mechanisms role of hormones in coordination

'Too much, slow down or too little, speed up' this is the of

  1. Feedback mechanism

  2. Autosomal disorder

  3. Genetic disorder

  4. None
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

'Too much, slow down or too little, speed up' -this is the feedback mechanism. the body has a mechanism to maintain a normal state. Whenever there is a change in this state there are messages through the body systems to increase if there is a fall below the normal, or decrease, if there is a rise above the normal. This kind of ordering for the opposite Is negative feedback to restore the normal state.

So, the correct answer is 'Feedback mechanism'.

Feedback mechanisms can be

  1. Positive

  2. Negative

  3. Both

  4. None
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

'Too much, slow down or too little, speed up' -this is the feedback mechanism. the body has a mechanism to maintain a normal state. Whenever there is a change in this state there are messages through the body systems to increase if there is a fall below the normal, or decrease if there is rise above the normal.  This kind of ordering for the opposite Is negative feedback to restore the normal state. examples of positive feedback mechanisms are very few. One example is that of uterine contractions during childbirth. The normal state of the uterus is uncontracted, one contraction instead of commanding to come to normal gives a message to continue further (positive feedback till the delivery is completed).

So, the correct answer is 'Both'.

Multiple choice biology nervous system of man reflex action innate and learned behaviour coordination in human beings- chemical control

Which one does not involve brain ?

  1. Spinal reflex

  2. Cerebral reflex

  3. Cranial reflex

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

Reflex is an involuntary and instantaneous action in response to a stimulus.

  1. A spinal reflex is a reflex action is controlled by spinal cord and related sensory afferent and an efferent muscle without the influence of brain like we remove our hand when we touch hot object.
  2. Cerebral reflex is an involuntary controlled action that involves brain like a closing of eyes in an exposure of light.
  3. Cranial nerve is mediated by the pathway that includes cranial nerves and brain includes the peripheral and central nervous system.
  4. Voluntary actions are those which depends on our will like eating, bathing etc. and controlled by the cerebellum.
The correct option is "Spinal reflex".

Which of the following are cerebral reflexes?


(i) a person pulls away his hand on touching a hot object.
(ii) a person spits out immediately when a fly enters his mouth while talking.
(iii) a person walking barefoot lifts his foot at once on stepping on to a nail.
(iv) a person's pupil contracts at once in the presence of bright light.

  1. (i) and (ii)

  2. (ii) and (iii)

  3. (iii) and (iv)

  4. (ii) and (iv)
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Cerebral reflexes involve the brain. Spitting out a fly (ii) and pupil contraction (iv) are controlled by centers in the brainstem (midbrain/medulla), whereas pulling a hand away (i) and lifting a foot (iii) are spinal reflexes.

Multiple choice biology nervous system of man reflex action innate and learned behaviour coordination in human beings- chemical control

Which of the following is not a reflex action?

  1. Salivation

  2. Sweating

  3. Withdrawal of hand when pinched by needle

  4. Blinking of eyes
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Reflex action is induced by the motor nerves. It is an involuntary and instant movement in response to a stimulus. A reflex action is done by neural pathway of reflex arc. In this, the action is done before the impulse reaches the brain. Out of the given options, sweating is not a reflex action. Salivation is a reflex action in which smell of food activate neural pathway and activates muscles and glands. This releases salivary juices. When someone is pinched by a needle, it activates neural pathway to evoke a response. The skin receptors quickly send nerve impulses to the spinal cord and response is relayed back. Apart from these, coughing, sneezing and blinking of eyes are also reflex actions.

Thus, the correct answer is 'Sweating.'

The kneejerk reflex in response to a mallet tap over the patellar ligament

  1. is a conditioned reflex

  2. is a monosynaptic reflex

  3. has its reflex centre in the spinal cord

  4. is mediated by a three neuron reflex are
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Monosynaptic Reflex is a simple reflex that involves the transmission of an impulse from a sensory neuron to a motor neuron across a single synapse in the spinal cord. The knee-jerk reflex action is an example of such type of reflex.

So, the correct option is 'is a monosynaptic reflex'.
