Final Answer:
The crisis involves the activation of the suprarenal medulla, releasing adrenaline and noradrenaline to initiate the "fight or flight" response in the sympathetic division of the autonomic nervous system.
The correct optionn is, (e) suprarenal medulla.
Step-by-step explanation:
The crisis in question corresponds to the activation of the suprarenal medulla. This adrenal gland component plays a pivotal role in the body's "fight or flight" response, a crucial aspect of the sympathetic division of the autonomic nervous system. When confronted with a stressful situation or threat, the sympathetic division is activated, leading to a series of physiological changes to prepare the body for immediate action.
The crisis begins with the stimulation of the sympathetic division's preganglionic fibers, which synapse with the chromaffin cells in the suprarenal medulla. These cells, in turn, release adrenaline (epinephrine) and noradrenaline (norepinephrine) into the bloodstream.
These catecholamines trigger a range of responses, including increased heart rate, elevated blood pressure, and the mobilization of energy stores. The overall effect is to enhance the body's physical and mental capabilities, optimizing it for a rapid and intense response to the perceived crisis.
