Question

During the breeding season, rough-skinned newts stop reproduction when exposed to a stressor. This process involves the neural, endocrine, and which other systems? What is the HPA pathway that is disrupted, i.e., name the three parts. The secretion of corticosterone elevates eCBs, marijuana-like molecules that neuro-modulate the hindbrain. What is an adaptive advantage of this system?

--simple and to the point. basically a bulleted short answer.

Answer 1

Male Newts (salamanders)clasp onto females Newts at the time of mating and stay the way for hours till they are exposed to a stressor.

The three parts of HPA that are disrupted HPA - Hypothalamus (HRH) Pituitary (ACTH) Adrenal (GC).

The advantage of this system is that the neuromodulation of the salamander when induced to a stressor allows the newt to unclamp from the female salamander so that it can escape the progress of danger and survive to reproduce for next time.
