That is the Adrenal gland. Another name for this is the Suprarenal gland.
The adrenal gland secretes epinephrine--also known as adrenalin.
The enlargement of the adrenal gland is called adrenal gland hypertrophy.
I seem to remember (but I'm not certain, mind you) it's the kidneys.
The Adrenal Gland. This gland is divided into two categories, the Adrenal Cortex and the Adrenal Medulla. The Adrenal Medulla produced epinephrine and norepinephrine. Epinephrine is also known as adrenaline, and the beginning of the word, "adrenal", is the same name as the gland, The Adrenal Gland.
The adrenal cortex, where aldosterone is produced, is part of the adrenal gland.
The central portion of the adrenal gland is known as the adrenal medulla. The function of the adrenal medulla is to secrete epinephrine into the body.
