Spinal cord | Structure and function of Spinal cord | Irtisams biology

Welcome to Irtisam’s Biology! 🧬 In this lecture, we cover a complete, high-yield breakdown of the Spinal Cord tailored specifically for Class 12 / FSc Part 2 Biology (Chapter: Coordination and Control). Master the structural anatomy, cross-section details, and reflex arc pathways to score full marks on your board exams and competitive entry tests! 📌 Key Concepts Covered: Anatomy & Protection: Position in the neural canal, vertebral column, meninges, and Cerebrospinal Fluid (CSF). Cross-Sectional Structure: Detailed breakdown of Gray Matter (H-shape/butterfly appearance, dorsal, ventral, and lateral horns) vs. White Matter (myelinated tracts). Spinal Nerves & Roots: Functions of Dorsal Root (sensory, dorsal root ganglion) and Ventral Root (motor). Reflex Arc Mechanism: Monosynaptic vs. Polysynaptic reflex pathways step-by-step. Key Functions: Processing center for spinal reflexes and conduction pathways between brain and body.
