Respuesta :
The hormone oxytocin is a positive feedback mechanism that enhances labor contractions.
Answer:
The Growth hormone (GH) secretion is part of a negative feedback mechanism involving GHRH.
Explanation:
The growth hormone is a peptidic hormone very important for development, it participates in growth, cell reproduction and regeneration of nearly every cell, tissue and organ in the human body and other organisms.
The Growth Hormone/IGF axis consists of a tightly regulated system by a feedback loop starting with the Growth Hormone (GH) secreted by the pituitary, then the GH production and secretion is controlled by Growth Hormone Releasing Hormone (GHRH) at the hypothalamus.
