Cheat Sheet
- Hormone Chemical Classes & Solubility -
Review the four major chemical classes: amino acid derivatives, peptides, steroids, and eicosanoids, noting that water-soluble hormones (peptides and catecholamines) circulate freely while lipid-soluble ones (steroids and thyroid hormones) require carrier proteins. For example, cortisol (a steroid) binds transcortin, whereas insulin (a peptide) diffuses in plasma. Remember "SALP" (Steroids, Amino, Lipid, Peptides) to keep classes straight when tackling anatomy and physiology 2 exam 1.
- Membrane vs Intracellular Receptors -
Water-soluble hormones activate second-messenger systems (e.g., cAMP, IP₃/DAG) via membrane receptors, while lipid-soluble hormones cross membranes to bind intracellular receptors and directly modulate gene transcription. A classic example is epinephrine using cAMP to trigger PKA, versus thyroid hormone binding nuclear receptors to regulate mRNA. Use the phrase "Surface for speed, nucleus for notes" to recall which hormones use which pathway.
- Hypothalamic - Pituitary Axis & FLAT PiG -
The hypothalamus controls the anterior pituitary via the hypophyseal portal system, releasing TRH, CRH, GnRH, and GHRH to regulate tropic hormones. Memorize the anterior pituitary hormones with FLAT PiG (FSH, LH, ACTH, TSH = tropic; Prolactin, GH = direct). Don't forget the posterior pituitary stores oxytocin and ADH produced by the hypothalamus - essential for a and p 2 exam 1 success.
- Feedback Mechanisms in Endocrine Regulation -
Negative feedback keeps most axes in check: high cortisol levels inhibit CRH and ACTH release, stabilizing the HPA axis. Positive feedback is rarer but crucial in processes like oxytocin-driven uterine contractions during labor. Recall "negate to regulate" for negative loops and link positive loops to a "push to the peak" scenario for anatomy and physiology 2 test 1.
- Endocrine Gland Cell Origins & Zones -
Differentiate cell types and zones: adrenal cortex zones "GFR - salt, sugar, sex" (zona glomerulosa, fasciculata, reticularis) and adrenal medulla from neural crest. In the thyroid, follicular cells synthesize T₃/T₄ while parafollicular (C) cells produce calcitonin. These cellular origins form the backbone for mastering a&p 2 exam 1 content.
