Muscles arrangement at joints | Human Skeletal and muscular system | L#16

Dive into the fascinating world of the Human Skeletal and Muscular System! This video (Chapter 12, F.Sc. 1st Year Biology - Punjab Text Book / National Curriculum of Pakistan 2025) explains the fundamental arrangement of skeletal muscles at movable joints. Learn about the Tendon, Origin, Insertion, and Belly of a muscle. We focus on the crucial Antagonistic Arrangement where muscles work in pairs (like Flexors and Extensors) to produce opposing actions. A detailed look at the Movement at the Knee Joint illustrates the opposing roles of the Hamstrings (flexion/bending) and the Quadriceps (extension/straightening). Perfect for students preparing for exams or anyone interested in human anatomy!
