ACTH (Adrenocorticotropic hormone) Subham Guha

Facts about ACTH Made in the pituitary gland and travel through bloodstream to adrenal glands Tissue: Adrenal cortex Chemical class: Peptide Stimulates adrenal cortex to secrete glucocorticoids Regulated by glucocorticoids and hypothalamic hormones

Role of ACTH Hypothalmus secretes releasing hormone to trigger pitutary for ACTH Travels down adrenal cortex to release cortisol to stimulate body cells to increase energy production Cortisol- maintains body stress

Hypo/Hyper Secretion Hyper: Excess growth of pituitary gland creates Cushing’s disease Obesity, slow growth rate, red face Hypo: Reduced stress response and skin depigmentation Addision’s disease: adrenal glands produce less hormones

Analogy A heater is like ACTH. It helps regulate the room temperature. If the room is cold, the heater turns on to warm the house.
