How Muscles Contract — Actin & Myosin Interaction (Contractile Proteins Explained)

Описание: 📌 Welcome to Lec 4 — How Muscles Contract!
In this video, we explain how muscles contract at the molecular level with easy-to-understand visuals and voice-over.

In this video you will learn:
✔ What are contractile proteins (Actin & Myosin)
✔ What is the Sliding Filament Theory
✔ How myosin heads bind to actin to form cross-bridges
✔ The role of ATP & Calcium ions in muscle contraction
✔ Step-by-step explanation of the cross-bridge cycling
✔ How muscles shorten and generate force

This lesson is perfect for biology students, anatomy & physiology learners, competitive exams, and anyone curious about how muscles work!
