Most Hormone Action is Regulated By

Question

Most hormone action is regulated by
A)negative feedback mechanisms.
B)positive feedback mechanisms.
C)the central nervous system.
D)digestive mechanisms.

Accepted Answer

Most hormone actions are regulated by negative feedback mechanisms, where the hormone inhibits its own production once a certain level of the hormone is reached. This helps maintain a balance within the body and prevents overproduction of hormones. Positive feedback mechanisms are less common and involve the hormone stimulating its own production, leading to an increase in production without a limit. The central nervous system and digestive mechanisms can influence some hormone actions, but they are not the primary regulators of hormone activity.
