Two catecholamines, norepinephrine and dopamine, act as neuromodulators in the central nervous system and as hormones in the blood circulation. The catecholamine norepinephrine is a neuromodulator of the peripheral sympathetic nervous system but is also present in the blood (mostly through "spillover" from the synapses of the sympathetic system).
The stress induced during exercise results in an increase in the hormones, epinephrine and norepinephrine, which are known for the body's "fight or flight" response. Increased secretion of catecholamines are a hormone response regulated by the sympathoadrenal system (SAS) and the hypothalamic-pituitary-adrenal axis (HPAA). [10]
The production of steroid hormones is called steroidogenesis, and involves a number of reactions and processes that take place in cortical cells. [5] The medulla produces the catecholamines, which function to produce a rapid response throughout the body in stress situations. [4] A number of endocrine diseases involve dysfunctions of the adrenal ...

The adrenal medulla is the principal site of the conversion of the amino acid tyrosine into the catecholamines; epinephrine, norepinephrine, and dopamine. Because the ANS, specifically the sympathetic division, exerts direct control over the chromaffin cells, the hormone release can occur rather quickly. [2]
The following is a list of hormones found in Humans. Spelling is not uniform for many hormones. Spelling is not uniform for many hormones. For example, current North American and international usage uses [ citation needed ] estrogen and gonadotropin, while British usage retains the Greek digraph in oestrogen and favours the earlier spelling ...
Stress, to a physiologist, means any situation that threatens the continued stability of the body and its functions. [61] Stress affects a wide variety of body systems: the two most consistently activated are the hypothalamic-pituitary-adrenal axis and the norepinephrine system, including both the sympathetic nervous system and the locus ...
Hormones flow in and out of the bloodstream and are able to bind to Target cells to activate the role of the hormone. This is with the help of the bloodstream flow and the secreting cell. Hormones regulate: metabolism, growth and development, tissue function, sleep, reproduction, etc. This diagram also lists the important hormones in a human body.
