Short Term Endocrine Stress Response Sequence
Understanding the sequence of events during the body's immediate reaction to stress is crucial. This response involves the nervous system and endocrine glands working together.
Step-by-Step Sequence Explained
The short-term endocrine response to stress follows a specific pathway:
- B. Stressor: The process initiates when the body encounters a perceived threat or challenge, known as a stressor.
- A. Hypothalamus: The brain's hypothalamus detects the stressor and acts as the control center.
- C. Sympathetic centers: The hypothalamus signals the sympathetic centers located in the brainstem and spinal cord.
- D. Sympathetic nerve & adrenal medulla: The activated sympathetic nerves directly stimulate the adrenal medulla, the inner part of the adrenal glands.
- E. Adrenaline & nor-adrenaline response: In response to sympathetic stimulation, the adrenal medulla rapidly releases hormones like adrenaline (epinephrine) and nor-adrenaline (norepinephrine) into the bloodstream. These hormones trigger the body's "fight-or-flight" physiological changes.
Therefore, the correct sequence is B, A, C, D, E.
