Chemical Coordination & Integration
Endocrine system ka poora NCERT: interactive gland map, animated HPA axis, hormone mechanisms, aur NEET drills. Ratta nahi, samajh ke yaad karo.
Fig 19.1: Location of endocrine glands · Tap a gland
Pituitary (Master Gland)
📖 Fig 19.2, Pg 241
Hormones secreted
- ▸Anterior: GH, TSH, ACTH, LH, FSH, PRL, MSH
- ▸Posterior: ADH (vasopressin), Oxytocin (stored only)
Key functions
- ✓Anterior thyroid, adrenal cortex, gonads, growth ko control karta hai
- ✓Posterior: water reabsorption (ADH), uterine contraction & milk ejection (oxytocin)
- ✓GH: bone & muscle growth; PRL: mammary gland development
Disorders (NEET favourite)
- Gigantism / Dwarfism: Puberty se pehle GH hyper/hyposecretion
- Acromegaly: Puberty ke BAAD GH hypersecretion
⚠️ NEET Trap
Posterior pituitary true endocrine gland NAHI hai: ye sirf hypothalamus ke banaye hormones store karta hai. Anterior asli secretory part hai.
NCERT-first content
Every gland, hormone, figure reference and exercise is lifted directly from NCERT Ch 19, with page numbers. NEET asks NCERT lines verbatim.
Interactive, not passive
Students tap glands, step through cascades, reveal mechanisms, and solve matchers. Active recall beats re-reading every time.
Trap-aware pedagogy
Every gland card carries a "NEET Trap": the exact misconception that costs marks. This is the Sarvaank mistake-engine philosophy.
Ye ek chapter hai. Poora NEET Biology isi quality pe ban chuka hai — Class 11 aur 12, dono.
