Physiology Mnemonics
Physiology is a subject of mechanisms, but a lot of marks still ride on remembering which hormones do what and in what order. These mnemonics lock down the endocrine axes, the cardiac properties, and the renal pathways that examiners return to every year. Say the acronym, then force yourself to explain the physiology behind each letter, because a mnemonic that cannot be unpacked is only half learned. Pair them with a quick diagram of the relevant axis or curve. Come back to them during your pre-exam revision and rebuild the full list aloud to test genuine recall.

Mnemonics and expansions
- **FLAT PiG:** FSH, LH, ACTH, TSH, Prolactin, ICSH, Growth hormone. Lists the hormones secreted by the anterior pituitary gland.
- **Grandma Goes Home To Cook Great Pizza:** GHRH, GHIH (somatostatin), Hypothalamus, TRH, CRH, GnRH, PIH. Recalls the hypothalamic releasing and inhibiting hormones that control the anterior pituitary.
- **Go Find Rex, Make Good Sex:** Glomerulosa makes Mineralocorticoids, Fasciculata makes Glucocorticoids, Reticularis makes Sex steroids. Pairs each adrenal cortex zone with the hormone class it produces.
- **CUSHING:** Central obesity, Unique fat (moon face), Skin striae, Hypertension and hyperglycaemia, Infections, Neuromuscular weakness, Gonadal dysfunction. Summarises the features of Cushing syndrome from cortisol excess.
- **PTH BIKES Calcium Up:** Bones (resorption), Intestine (via vitamin D), Kidney (reabsorption). Shows the three target organs through which parathormone raises blood calcium.
- **A Big Dog Found:** Alpha cells (glucagon), Beta cells (insulin), Delta cells (somatostatin), F cells (pancreatic polypeptide). Matches each islet of Langerhans cell type to its secretion.
- **Good Teachers Can Always Grade:** Glucagon, Thyroxine, Cortisol, Adrenaline, Growth hormone. Lists the counter-regulatory hormones that raise blood glucose.
- **Every Really Cute Cat:** Excitability, Rhythmicity, Conductivity, Contractility. Names the four fundamental properties of cardiac muscle.
- **Some Animals Bring Big Presents:** SA node, AV node, Bundle of His, Bundle branches, Purkinje fibres. Traces impulse conduction through the specialised cardiac system.
- **GTS:** Glomerular filtration, Tubular reabsorption, Tubular secretion. Covers the three processes that together form urine.
