Now-a-days cornea transplantation is very popular. The reason is that it

  • is easy to preserve

  • transplanted very easily

  • can be easily obtained

  • does not link with blood supply and immune system


does not link with blood supply and immune system

Cornea transplantation is very popular these days because the cornea has no blood supply, so it is away from the immune system of the body.


Ventricles are related to

  • heart only

  • brain only

  • both 'a' and 'b'

  • none of these


both 'a' and 'b'

Ventricles are related to both heart and brain. Mammalian heart is four chambered. The upper two chambers known as right and left auricle and the lower as right and left ventricles. In brain there are four ventricles. Ventricle Ist and II (lateral ventricles) are cavities of two cerebral hemispheres. IIIrd ventricle (diocoel) is cavity of diencephalon and IV ventricle (metacoel) is cavity of medulla oblongata.


If a stimulus, several times greater than the threshold stimulus is provided to a muscle fibre, it will

  • contract with a larger force

  • contract with a smaller force

  • contract with the same force

  • undergo tetany.


contract with the same force

A muscle fibre would contract only when it receives stimulation of certain intensity called threshold stimulus. Response of a muscle fibre to a stimulus is not proportional to its intensity. It is absent when the intensity is subliminal. Muscle fibre contracts to the maximum whether the stimulus has threshold value or supraliminal value.


Organ of Corti is found in

  • heart

  • kidneys

  • inner ear

  • nasal chamber


inner ear

Organ of Corti are found in cochlear channel (internal ear) and are responsible for hearing. Ear is concerned both with hearing and balance, semicircular canals are responsible for balance when body is in motion.


Assertion : The imbalance in the concentration of Na+, K+ and proteins generates the resting potential.

Reason : To maintain the unequal distribution of Na+ and K+, the neurons use electrical energy.

  • If both assertion and reason are true and reason is the correct explanation of assertion.

  • If both the assertion and reason are true but reason is not the correct explanation of assertion.

  • If assertion is true but reason is false.

  • If both the assertion and reason are false.


If assertion is true but reason is false.

To maintain the unequal distribution of Na+ and K+ ion, the neuron uses chemical energy in the form of ATP to actively transport Na+ ion out of the cell and move K+ inside the cell.


Which of the following is the part of mid brain of rabbit?

  • Diencephalon

  • Cerebrum

  • Corpora quadrigemina

  • None of the above


Corpora quadrigemina

The dorsal part of mid brain (mesencephalon) is in the form of two pairs (i.e., four) of spherical optic lobes (corpora quadrigemina) located behind the pineal body optic lobes are reduced merely as reflex centres of visual and auditory.


Unidirectional transmission of a nerve impulse through nerve fibre is due to the fact that

  • nerve fibre is insulated by a medullary sheath

  • sodium pump starts operating only at the cyton and then continues into the nerve fibre

  • neurotransmitters are released by dendrites and not by axon endings

  • neurotransmitters are released by the axon endings and not by dendrites.


neurotransmitters are released by the axon endings and not by dendrites.

Neurotransmitters are molecules that fit like a lock and key into a specific receptor. The receptor is located on the next cell in the line. Therefore, nerve impulses cannot travel in the opposite direction, because nerve cells only have neurotransmitter storage vesicles going one way, and receptors in one place.


A person is wearing spectacles with concave lenses for correcting vision. While not using the glasses, the image of a distant object in his case will be formed

  • on the blind spot

  • behind the retina

  • in front of the retina

  • on the yellow spot


in front of the retina

As the person uses spectacles having concave lens, he must be suffering from myopia or short-sightedness. Here the eyeballs become elongated, so that parallel rays are focussed in front of retina.

Myopia is an eye disorder where light focuses in front of retina. This causes distant objects appear normal. It is also known as short- sightedness.


The total number of nitrogenous bases in human genome is estimated to be about

  • 3.5 million

  • 35 thousand

  • 35 million

  • 3.1 billion.


3.1 billion.

Genome size is usually stated as the total number of base pairs; the human genome contains roughly 3 billion base pairs.


Sella Turcica is found

  • in bones

  • in joints

  • nearby pituitary

  • nearby thyroid


nearby pituitary

Sella turcica is found in the sphenoid bone behind the chiasmatic groove and tuberculum sellae. Pituitary is present in it. It is a depression in sphenoid bone of cranial cavity.
