Epinephrine
Region: Suprarenal Medulla
Primary Targets: Most Cells
Hormonal Effects: Increases cardiac activity, blood pressure, glycogen breakdown, blood glucose levels; releases lipids by adipose tissue
Regulatory Control: Stimulated during sympathetic activation by sympathetic preganglionic fibers
-
Norepinephrine
Region: Suprarenal Medulla
Primary Targets: Most Cells
Hormonal Effects: Increases cardiac activity, blood pressure, glycogen breakdown, blood glucose levels; releases lipids by adipose tissue
Regulatory Control: Stimulated during sympathetic activation by sympathetic preganglionic fibers
-
Mineralocorticoids (primarily aldosterone)
Region: Suprarenal Cortex - Zona Glomerulosa
Primary Targets: Kidneys
Hormonal Effects: Increase renal absorption of Na+ and water (especially in the presence of ADH) and accelerate urinary loss of K+
Regulatory Control: Stimulated by angiotensin II, elevated plasma K+ or a fall in plasma Na+; inhibited by ANP and BNP
-
Glucocorticoids (cortisol{hydrocortisone}, corticosterone)
Region: Suprarenal Cortex - Zona Fasciculate
Primary Targets: Most Cells
Hormonal Effects: Release amino acids from skeletal muscles and lipids from adipose tissues; promote liver formation of glucose and glycogen; promote peripheral utilization of lipids; anti-inflammatory effects
Regulatory Control: Stimulated by ACTH from Adenohypophysis
-
Androgens
Region: Suprarenal Cortex - Zona Reticularis
Primary Targets: Most Cells
Hormonal Effects: Not important in adult men; encourages bone growth, muscle growth, and blood formation in children and women
Regulatory Control: Stimulated by ACTH
