What is likely to occur after signals are sent from the suprachiasmatic nucleus to the pineal gland

A)  Circadian rhythms will be reset. 
B)  Alpha rhythms will be generated. 
C)  Sleep will end. 
D)  The individual will begin to dream.

Suprachiasmatic Nucleus

A tiny region in the brain's hypothalamus responsible for controlling circadian rhythms, essentially serving as the body's internal clock.

Pineal Gland

A small endocrine gland in the brain that produces melatonin, a hormone that regulates sleep patterns and seasonal biological rhythms.

  • Examine the notion of circadian rhythms and their effect on daily operations.

Final Answer :
A
Explanation :
The suprachiasmatic nucleus controls the circadian rhythm and sends signals to the pineal gland to release the hormone melatonin. Melatonin resets the circadian rhythm based on external cues such as light and darkness.

Therefore, Choice A (circadian rhythms will be reset) is the most likely occurrence after signals are sent from the suprachiasmatic nucleus to the pineal gland.
