Breakdown the Problem

To identify which organ controls the response to stress, particularly in the context of the general adaptation syndrome, we need to analyze the roles of the hypothalamus, adrenal gland, liver, and pituitary gland in stress response.

Relevant Concepts

1. General Adaptation Syndrome (GAS): This concept, proposed by Hans Selye, involves three stages of response to stress: alarm, resistance, and exhaustion. Various organs and hormones are involved in these stages.

2. Key Organs in Stress Response:

   • Hypothalamus: It is the control center for the autonomic nervous system and can trigger the stress response.
   • Adrenal Gland: It produces hormones like cortisol and adrenaline, which are crucial in the body's response to stress.
   • Liver: Plays a role in metabolism but is not primarily responsible for stress response.
   • Pituitary Gland: It releases hormones that regulate various functions, including acting on the adrenal gland.

Analysis and Detail

1. The hypothalamus detects stress and sends signals to the pituitary gland.
2. The pituitary gland then releases adrenocorticotropic hormone (ACTH), which stimulates the adrenal glands.
3. The adrenal glands respond by releasing corticosteroids (like cortisol) and catecholamines (like adrenaline), which prepare the body for the 'fight or flight' response.

Verify and Summarize

The key role in controlling and coordinating the stress response lies primarily with the hypothalamus and the adrenal glands. While the pituitary gland also plays a crucial role as part of the hypothalamic-pituitary-adrenal (HPA) axis, the adrenal glands ultimately execute the stress response by producing stress hormones.

Final Answer

The organ that controls the response to stress, specifically within the framework of the general adaptation syndrome, is primarily the Adrenal gland.
