Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R):
Assertion (A): | The same neurotransmitter, acetylcholine, may be inhibitory at some places like heart and excitatory elsewhere like alimentary canal. |
Reason (R): | The cells involved in each case have different receptors for ACh that produce different effects. |
In the light of the above statements choose the correct answer from the options given below:
1. | Both (A) and (R) are True and (R) is the correct explanation of (A). |
2. | Both (A) and (R) are True but (R) is not the correct explanation of (A). |
3. | (A) is True but (R) is False. |
4. | Both (A) and (R) are False. |
Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R):
Assertion (A): | Action potential propagation in unmyelinated neurons is faster than in myelinated neurons. |
Reason (R): | Myelin is a complex polysaccharide and it slows the conduction of the impulse along the axonal membrane. |
In the light of the above statements choose the correct answer from the options given below:
1. | Both (A) and (R) are True and (R) is the correct explanation of (A). |
2. | Both (A) and (R) are True but (R) is not the correct explanation of (A). |
3. | (A) is True but (R) is False. |
4. | Both (A) and (R) are False. |
Assertion: The stapes, though the smallest bone in the body, is able to vibrate the perilymph in the vestibular duct.
Reason: The foot plate of stapes is much smaller than the tympanic membrane.
1. Both assertion and reason are true and the reason is the correct explanation of the assertion.
2. Both assertion and reason are true but the reason is not the correct explanation of the assertion.
3. Assertion is true but reason is false.
4. Both assertion and reason are false
Assertion: Auditory transduction is the function of the organ of Corti.
Reason: Organ of Corti is located in the scala media of cochlea of inner ear.
1. Both assertion and reason are true and the reason is the correct explanation of the assertion.
2. Both assertion and reason are true but the reason is not the correct explanation of the assertion.
3. Assertion is true but reason is false.
4. Both assertion and reason are false.
Assertion: Corneal transplant have a few problems of rejection and generally are well accepted.
Reason: Cornea has a rich vascular supply that helps in fighting the cells responsible for graft rejection.
1. Both assertion and reason are true and the reason is the correct explanation of the assertion.
2. Both assertion and reason are true but the reason is not the correct explanation of the assertion.
3. Assertion is true but reason is false.
4. Both assertion and reason are false
Assertion: Contraction of ciliary muscles reduces the refractory power of the lens.
Reason: Contraction of ciliary muscles leads to increase in the pull of suspensory ligaments making lens more flat.
1. Both assertion and reason are true and the reason is the correct explanation of the assertion.
2. Both assertion and reason are true but the reason is not the correct explanation of the assertion.
3. Assertion is true but reason is false.
4. Both assertion and reason are false.
Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R):
Assertion (A): | Most of the synapses in vertebrates conduct information in only one direction. |
Reason (R): | Only the postsynaptic cells can bind and respond to neurotransmitters. |
In the light of the above statements choose the correct answer from the options given below:
1. | Both (A) and (R) are true and (R) is the correct explanation of (A). |
2. | Both (A) and (R) are true but (R) is not the correct explanation of (A). |
3. | (A) is true but (R) is false. |
4. | Both (A) and (R) are false. |
Assertion: Action potentials usually conducted in only one direction along an axon – from axon hillock towards the terminal nerve endings.
Reason: The axon hillock has a higher membrane potential than the terminals of the axon.
