Final answer:
The body releases cortisol to help put an end to the stress response. Hense, correct otpion is "c. Cortisol".
Step-by-step explanation:
Cortisol, often referred to as the "stress hormone," is released by the adrenal glands in response to stress. While epinephrine (adrenaline) and dopamine are also involved in the stress response, cortisol plays a key role in regulating and ultimately dampening the effects of stress.
When the body perceives stress, the hypothalamus activates the release of corticotropin-releasing hormone (CRH), which signals the pituitary gland to release adrenocorticotropic hormone (ACTH). ACTH then stimulates the adrenal glands to produce and release cortisol. Cortisol helps the body cope with stress by regulating various physiological processes, including metabolism, immune response, and blood pressure.
One of cortisol's primary functions is to provide a negative feedback loop to the initial stress response. Once released, cortisol signals the hypothalamus and pituitary gland to reduce further production of CRH and ACTH, ultimately helping to terminate the stress response.
While epinephrine (adrenaline) and dopamine are also involved in the stress response, cortisol is particularly crucial for the prolonged and adaptive regulation of the body's physiological functions during and after a stressful event.
