Adrenal medulla
epinephrine and norepinephrine are released by the adrenal glands
Adrenal gland, specifically its inner cortex.
The adrenal gland (more specifically the Adrenal Medulla).
Adrenal glands produce hormones such as estrogen, progesterone, steroids, cortisol, and cortisone, and chemicals such as adrenalin (epinephrine), norepinephrine, and dopamine. When the glands produce more or less hormones than required by the body, disease conditions may occur.
The adrenal glands produce steroid hormones such as testosterone, aldosterone, and cortisol. The medulla is the interior portion of the adrenal glands and it produces epinephrine and norepinephrine.
The adrenal medulla, which is part of the adrenal glands, is responsible for producing and releasing epinephrine (also known as adrenaline). Epinephrine helps to regulate the body's "fight or flight" response in times of stress or danger.
Several such as cortisol, cortisone, alderstone, epinephrine, norepinephrine, adrenaline, and finally, androgens which consist of androstenedione and DHEA which together are converted to testosterone.
The adrenal glands are associated with the production of epinephrine and norepinephrine, which are both involved in the body's "fight or flight" response to stress. These hormones help prepare the body for intense physical activity by increasing heart rate, dilating airways, and mobilizing energy stores.
Epinephrine and norepinephrine are two very structurally similar molecules. They've both involved in the sympathetic part of your autonomic nervous system. Epinephrine (also known as adrenaline) is a hormone which is secreted from the adrenal medulla when activated by the sympathetic nervous system (during times of stress). Norepinephrine (also known as noradrenaline) is a neurotransmitter that is released by neurons in the sympathetic nervous system. Epinephrine and norepinephrine generally produce the same effects as they both interact with adrenergic receptors in the body. Epinephrine is structurally different from norepinephrine as epinephrine has a methyl group (-CH3) attached to the nitrogen atom (making it a secondary amine), whereas norepinephrine is just a primary amine.

epinephrine and nonrepinephrine are both made by the Adrenal Glands that are located on top of the kidneys. More specifically the Adrenal Cortex (outerpart) makes those two hormones.
Adrenal glands
Epinephrine can be synthesized through a multi-step process starting with the amino acid tyrosine. Tyrosine is converted into L-DOPA, which is then decarboxylated to form dopamine. Dopamine undergoes hydroxylation to produce norepinephrine, and finally, methylation of norepinephrine leads to the formation of epinephrine. This synthesis typically occurs in the adrenal medulla of the adrenal glands in response to stress stimuli.
