Signaling pathways of endocrine hormones

Concise, exam-focused slides mapping endocrine signaling pathways by second messengers (cAMP, cGMP, IP3), receptor classes (GPCR, receptor tyrosine kinase, non-receptor tyrosine kinase), and intracellular/steroid receptors, with high-yield mnemonics for rapid recall.

Covers hypothalamic and pituitary hormones (CRH, GHRH, GnRH, TRH; FSH, LH, ACTH, TSH, MSH), posterior pituitary actions (ADH V1/V2, oxytocin), calcium regulators (PTH, calcitonin), metabolic hormones (insulin, glucagon), placental hCG, cytokines (IL-2, IL-6, IFN), and hematopoietic factors (G-CSF, EPO, TPO).

Highlights BAD GraMPa for cGMP (BNP, ANP, NO), GOAT HAG for IP3 (Histamine H1, Ang II, Gastrin), and GET a JAKed PIG for JAK/STAT (Prolactin, GH) alongside MAP kinase growth factors (IGF-1, FGF, PDGF, EGF).

Ideal for medical students and exam prep needing a clean pathway overview without clinical advice.
