I- Adrenal medullaالمركز.
They are amino acid derivatives (synthesized from tyrosine) and function as:
II- Adrenal cortex: reacts to stress.
Secretes Thymosin: a peptide.It stimulates T lymphocytes.
Protein hormones affect target cells via receptors on the membrane protein
Steroid hormones inter the target cells and trigger protein synthesis via receptors in the nucleus.
