Brain structures that schedule rhythmic variations in bodily functions by triggering them at the appropriate times are called:
A)biological clocks
B)circadian timers
C)zeitgebers
D)arhythmics

Question

Quizplus · Accepted Answer

Biological clocks are responsible for scheduling the rhythmic variations in bodily functions by triggering them at the appropriate times. These clocks are found in various brain structures, such as the suprachiasmatic nucleus (SCN) in the hypothalamus, and help regulate circadian rhythms, which refer to the physical, mental, and behavioral changes that follow a roughly 24-hour cycle. While circadian timers and zeitgebers (external cues that help entrain circadian rhythms) are related to biological clocks, they do not refer specifically to the brain structures that schedule rhythmic variations in bodily functions. Arhythmics, on the other hand, refer to substances or conditions that disrupt the normal rhythm of bodily functions rather than those that trigger them at appropriate times.
