Brain Anatomy and Blood Supply Quiz

What is the primary function of neurons in the brain?

• To store nutrients for the brain

• To enable functions like thinking and learning

• To connect different parts of the body

• To protect the brain from injury

Which part of the brain is primarily responsible for coordination and balance?

• Frontal lobe

• Brainstem

• Cerebellum

• Cerebrum

Which lobe of the cerebrum is mainly involved in processing visual information?

• Occipital lobe

• Parietal lobe

• Temporal lobe

• Frontal lobe

What is the main reason the brain requires a rich blood supply?

• To remove waste products

• To supply glucose and oxygen

• To support neuron growth

• To maintain its temperature

Which artery is formed by the merging of the two vertebral arteries?

• Anterior cerebral artery

• Middle cerebral artery

• Basilar artery

• Internal carotid artery

What is the function of the Circle of Willis in the brain?

• To connect the brain to the spinal cord

• To regulate brain temperature

• To store nutrients

• To provide collateral circulation

Which artery supplies blood to the inner parts of the frontal lobes?

• Middle cerebral artery

• Anterior cerebral artery

• Basilar artery

• Posterior cerebral artery

What happens if there is a blockage in one of the internal carotid arteries?

• The Circle of Willis compensates by rerouting blood

• The brainstem becomes more active

• The brain stops receiving blood

• The cerebellum takes over the function

Which artery is NOT part of the Circle of Willis?

• Basilar artery

• Middle cerebral artery

• Anterior cerebral artery

• Posterior communicating artery

What is the significance of the Circle of Willis in preventing brain injury?

• It allows blood to bypass blockages

• It connects the brain to the heart

• It strengthens the skull

• It stores extra blood for emergencies
