Question 1

Which of the following best describes the function of the myelin sheath in a neuron?

It insulates and protects axons, speeding up neural conduction.

Question 2

During the action potential, what is the primary event that occurs when the neuron is stimulated past its threshold?

Accepted Answer

Positively charged sodium ions rush inside the neuron.

Question 3

A patient has difficulty understanding spoken language after a stroke. Which brain area is most likely affected?

Accepted Answer

Wernicke's area in the left temporal lobe

Question 4

Which of the following best explains how neurotransmitters are removed from the synaptic gap after signaling?

Accepted Answer

They are broken down by enzymes or taken back into the presynaptic neuron via reuptake.

Question 5

Which neuroimaging technique uses a radioactive tracer to highlight areas of brain activity?

Accepted Answer

PET scan

Question 6

A researcher wants to study the effects of stimulating a specific brain region in a noninvasive way. Which technique should they use?

Accepted Answer

Question 12

Which statement best describes the function of the association areas of the cortex?

Accepted Answer

They are involved in higher mental functions such as learning, memory, and language.

Question 13

Which of the following best describes the role of the pituitary gland?
