_______ is the largest part of the brain.

  1. Cerebellum

  2. Cerebrum

  3. Ventricles

  4. Pons

  1. The basilar artery

  2. The anterior cerebral artery

  3. The anterior communicating artery

  4. The internal carotid artery

  5. The posterior communicating arteries
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

It arises from the confluence of the two vertebral arteries at the junction between the medulla oblongata and the pons. The basilar artery and middle cerebral arteries, supplying the brain, are not considered a part of the circle.

Multiple choice

Assertion: ABCD syndrome is a cell migration disorder of the neurocytes of the gut and sensorineural deafness. Reason: Skin of an affected individual is albino pale besides the brown patches of mispigmented skin.

  1. A and R both are correct and R is the correct explanation of A.

  2. A and R both are correct and R is not the correct explanation of A.

  3. A is correct and R is incorrect.

  4. A is incorrect and R is correct.

  5. A and R both are incorrect.
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

This option is correct. ABCD syndrome is a cell migration disorder of the neurocytes of the gut and sensorineural deafness is caused due to mutation in the endothelin B receptor gene and skin of an affected individual is albino pale besides the brown patches of mispigmented skin.

Multiple choice

Which among the following parts of brain provides remarkable distinctions between humans and other animals?

  1. Cerebral cortex

  2. The limbic system

  3. The cerebellum

  4. The thalamus

  5. The spinal cord
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The cerebral cortex is the portion of the brain that provides remarkable distinctions between humans and other animals. It enables humans not only to receive and interpret all kinds of sensory information, such as colour, odor, taste, and sound, but also to remember, analyze, interpret, make decisions, and perform a host of other higher brain functions.
