Adrenal gland

• found at the level of T12
• divided into 2 area : adrenal cortex and adrenal medulla

Adrenal medulla

• form the core of adrenal gland
• made up by chromaffin cells that produce

1. catecholamine : adrenaline and noradrenaline
2. dopamine

Adrenal cortex

• form the outer layer of adrenal gland
• consist of 3 layers : zona glomerulosa ,zona fasciculata, zona reticularis
• zona glomerulosa :
  

1. the outermost layer of the cortex
2. produce mineralocorticoids mainly aldosterone

• zona fasciculata:

1. middle layer
   
2. produce glucocorticoids mainly cortisol

• zona reticularis

1. innermost layer
2. produce small number of androgens
