Neurons & Brain Structure

Question 1

Which list correctly matches each of the four cerebral‑cortex lobes with one of their main functions?

Accepted Answer

Frontal lobe – planning and decision making; Parietal lobe – processing touch and spatial information; Temporal lobe – hearing and memory; Occipital lobe – visual processing.

Answer

Frontal lobe – interpreting touch sensations; Parietal lobe – planning movements; Temporal lobe – visual processing; Occipital lobe – hearing.

Answer

Frontal lobe – controlling emotions; Parietal lobe – processing sound; Temporal lobe – language comprehension; Occipital lobe – balance and coordination.

Answer

Frontal lobe – movement coordination; Parietal lobe – storing long‑term memories; Cerebellum – visual interpretation; Temporal lobe – spatial reasoning.

Question 2

After practicing a new basketball dribbling move every day for several weeks, Maya can now dribble twice as fast as when she first started. Which statement best explains how Maya’s brain helped her improve this skill?

Accepted Answer

The neural pathways that control dribbling have become stronger and transmit signals more quickly.

Answer

The muscles in her arms have grown larger, so they can move faster.

Answer

Her brain has added new lobes dedicated to dribbling.

Answer

The blood vessels in her brain now deliver oxygen twice as fast to the dribbling area.

Question 3

Lena has been practicing how to solve a Rubik’s Cube. At first it took her about 2 minutes per cube, but after practicing 20 minutes each day for two weeks she can solve it in 30 seconds. Which statement best explains why she can solve it faster now?

Accepted Answer

Repeated practice strengthens the connections between the neurons involved, so the signal travels more quickly.

Answer

Repeated practice causes the brain to grow new neurons that replace the old ones, so the old pathways are no longer used.

Answer

The brain stores the whole solution in memory, so no neural signals are needed the next time.

Answer

Practice makes the neurons fire less often, which speeds up the overall process.
