Sliding filament causes contraction of muscle

Sliding filament model of muscle contraction: Video, Causes, & Meaning | Osmosis

Sahith krishna on Instagram: "Muscle Contraction – Sliding Filament Theory Actin & myosin filaments slide → muscle shortens. 🔹 Steps: 1. Nerve impulse → Ca²⁺ released from sarcoplasmic reticulum. 2. Ca²⁺ binds troponin → tropomyosin shifts → actin exposed. 3. Cross-bridge formation → myosin head binds actin (ATP needed). 4. Power stroke → myosin pulls actin → contraction. 5. ATP attaches → cross-bridge detaches. 6. Relaxation when Ca²⁺ pumped back. 📌 For more lectures: drkrishnalectures 📲 Wha

World of Biology on Instagram: "Muscle contraction is the process by which muscle fibers shorten and generate force, enabling movement. It occurs when muscle cells (or fibers) respond to signals from the nervous system, causing changes in their internal structure. . .
