Question 1

Match the lobe of the cerebral cortex with its function. Names of lobes may be used more than once.
-Stimulation of specific areas cause muscles to move
A)Frontal lobe
B)Parietal lobe
C)Temporal lobe
D)Occipital lobe

Accepted Answer

The stimulation of specific areas within the frontal lobe results in the movement of muscles. This is due to the fact that the frontal lobe is responsible for motor function and voluntary movement control.

Answer: B
 The parietal lobe is responsible for processing sensory information from the body, including touch, temperature, and pain. Stimulation of specific areas within the parietal lobe can also cause movement, but this is more related to movement in response to sensory input.

Answer: C
 The temporal lobe is responsible for processing auditory information and is involved in memory and emotion. Stimulation of specific areas within the temporal lobe would not typically result in movement.

Answer: D
 The occipital lobe is responsible for processing visual information. Stimulation of specific areas within the occipital lobe would not typically result in movement.
