Division of Adrenal Gland Synthesis and Location Each gland is divided into two parts An outer cortex and An inner medulla Developed from different embryonic tissues, it secretes various hormones. The adrenal/ suprarenal is a paired gland and located near the upper portion of each kidney.
Division of Adrenal Gland Each gland is divided into two parts a. An outer cortex and
b. An inner medulla
• The cortex and medulla of the adrenal gland are just like the anterior and posterior lobes of the pituitary gland.
• The adrenal cortex is essential to life because it has very important functions to perform, but the medulla may be removed with no life-threatening effects.
• Hypothalamus effects and influences both portions of the adrenal gland but it involves different mechanisms i.e. adrenal cortex is regulated by negative feedback which involves hypothalamus and adrenocorticotropic hormone.
• Medulla is regulated by nerve impulses of hypothalamus.
