Human Brain in 3D | Class 11 NEET Biology

What you're seeing

NCERT ke hisaab se brain ke 3 divisions — forebrain, midbrain, hindbrain. Inhe ghuma ke explore karo, ya Parts mode me cerebrum, thalamus, cerebellum, medulla pe tap karke functions dekho.

Key NEET facts

▸Forebrain: Cerebrum + thalamus + hypothalamus — Thinking, memory, voluntary action, sensory perception. Thalamus = signals ka relay, hypothalamus = homeostasis (temp, hunger, thirst).
▸Midbrain: Visual & auditory reflexes — Forebrain aur hindbrain ke beech chhota part (corpora quadrigemina).
▸Hindbrain: Cerebellum + pons + medulla — Balance/coordination + vital involuntary functions (breathing, heartbeat).
▸Cerebellum: Balance & coordination — 'Little brain'. Muscular activity coordinate karta. Damage → movements ladkhadaa jaate.
▸Medulla oblongata: Vital centre — Breathing, heartbeat, BP aur reflexes (cough, vomit, sneeze) control karti. Life-critical.

Memory trick

Brain = 3 dibbe: FORE-brain (cerebrum + thalamus + hypothalamus → sochna + homeostasis), MID-brain (visual/auditory reflexes), HIND-brain (cerebellum = balance + pons + medulla = breathing/heartbeat). Medulla = 'Maut-control'.

Common questions

Cerebrum aur cerebellum me kya farak hai?›

Cerebrum sabse bada part hai (forebrain) — sochna, decision, voluntary movement, sensation aur vision sambhalta hai. Cerebellum hindbrain ka part hai, peeche-neeche, aur balance, posture aur muscular coordination control karta hai. Cerebrum 'kya karna hai' decide karta, cerebellum usse 'smoothly' karwata.

Medulla oblongata life-critical kyun hai?›

Medulla oblongata hindbrain ka part hai jo breathing, heartbeat aur blood pressure jaise involuntary vital functions control karti hai, plus cough/vomit/sneeze reflexes. Inke bina jeena possible nahi — isi liye medulla ko damage life-threatening hota hai.

Cerebrum ke 4 lobes ke functions kya hain?›

Frontal lobe — voluntary movement, reasoning, speech (Broca's area). Parietal lobe — touch, temperature, pain (sensory). Temporal lobe — hearing, smell, memory aur language samajhna (Wernicke's). Occipital lobe — vision.
