Involuntary Actions
(Breathing, Circulation, Heartbeat)

✅ Meninges of Brain
→ Duramater
→ Piamates
→ Arachnoid Mater

✅ Brain Hemispheres
→ Right Cerebral Hemisphere (Left Side)
→ Left Cerebral Hemisphere (Right Side)
→ Corpus Callosum

✅ Cerebrospinal Fluid (CSF)
→ Shock Absorbing Function

✅ Spinal Cord
→ Butterfly Shape
→ Located in Vertebral Column
→ White Matter & Grey Matter
→ Reflex Actions

✅ Mechanism of Reflex Action
→ Hot Object → Epithelial Tissues
→ Pain Receptors
→ Sensory Neurone
→ Associative Neurone
→ Motor Neurone
→ Effectors (Muscles, Hands, Legs)

✅ Peripheral Nervous System (PNS)
→ Fight or Flight Conditions
→ Autonomic Nervous System
→ Sympathetic Nervous System
→ Heartbeat (Normal)
→ Blood Pressure (Normal)
→ Blood Flow (Normal)
→ Retina (Normal)
→ Parasympathetic Nervous System
→ Heart Beat
→ Retina Dilate
→ Blood Flow
→ Blood Pressure
→ Somatic Nervous System
→ Voluntary Actions
→ Involuntary Actions

✅ Chemical Coordination
→ Hormones
→ Chemical Messengers
→ Nerve Impulse Transmission
→ Specialized Cells & Glands
→ Exocrine Gland (Duct)
→ Endocrine Gland

✅ Endocrine Glands
→ Pituitary Gland
→ Thyroid Gland
→ Para Thyroid Gland
→ Pancreas
→ Adrenal Gland
→ Gonads

✅ Pituitary Gland — Complete Detail
→ Master Gland of Body
→ Attached with Hypothalamus
→ Pea Shaped — 0.5gm
→ Growth Hormone
→ Growth & Development
→ Cell Division
→ Gigantism
→ Dwarfism
→ ACTH → Adrenal Gland
→ LH (Luteinizing Hormone)
→ Mammary Glands
→ TSH → Thyroid Gland
→ Oxytocin
→ Smooth Muscles Contraction
→ Clot Dissolving Drugs
→ Child Birth
→ ADH → Stress

✅ Adrenal Gland
→ Located on Kidney
→ Water Reabsorption
→ ADH
→ Aldosterone

✅ Pancreas — Dual Function
→ Endocrine → Insulin & Glucagon
→ Exocrine → Pancreatic Juice
→ Blood Glucose Regulation:
→ Food (Carbohydrates) → Fasting
→ Blood Glucose Level ↑
→ Pancreas β Cells → Insulin
→ Insulin → Normal Blood Glucose
→ Glucagon
→ Inhibit Catabolism
→ Promote Catabolism
→ Promote Water Reabsorption
→ Inhibit Anabolism

✅ Gonads
→ Reproductive Organ Development
→ Testosterone → Testes
→ Estrogen → Ovaries

✅ Photoreceptors
✅ Sonoreceptors

✅ Disorders — Complete Detail
→ Epilepsy
→ Nerve Impulse Overgenerate
→ Body Shrivels
→ Bites own Tongue
→ Hands & Legs become Curved
→ Blood Clotting
→ Blood Vessels → Brain
→ Blood Viscosity ↑
→ Spinal Cord
→ Treatment: Antiepileptic Drug
→ Paralysis
→ Stroke


🎯 This video is perfect for:
→ Class 10 Students (Punjab / Federal / KPK Board)
→ Students preparing for Board Exams 2025
→ Anyone who wants to understand Biology easily!

📌 Key Points to Remember:
→ Cerebrum = LARGEST part of brain
→ Medulla Oblongata = involuntary actions
→ Cerebellum = movement & balance
→ CSF = shock absorber for brain
→ Pituitary = MASTER gland (0.5gm)
→ Pancreas has DUAL function
→ Insulin = lowers blood glucose
→ Glucagon = raises blood glucose
→ Adrenal Gland sits on Kidney
→ Testosterone = Testes development
→ Estrogen = Ovaries development
→ Epilepsy treated with Antiepileptic drugs
→ Paralysis caused by Stroke
