Tutorials

Myosin and Actin:

This Khan Academy video describes how the proteins myosin and actin interact to produce a mechanical force on muscles, allowing them to move.

Type: Tutorial

Tropomyosin and Troponin and Their Role in Muscle Contraction:

This Khan Academy video explains the role that tropomyosin and tropinin play in muscle contraction. The role of the calcium ion concentrations are also explained.

This challenging tutorial addresses the concept at a high level of complexity.

Type: Tutorial

Action Potentials and Muscle Contraction:

This tutorial will help you to visualize and understand how nerve impulses cause muscle contractions. The neurons and muscle tissue conduct electrical current by moving ions across cellular membranes. The signal will travel through the tissue and trigger the contraction of individual sarcomeres, the functional units of muscle. This tutorial explains the neuromuscular junction where the synapse occurs.

Type: Tutorial

Muscle Contraction:


This tutorial will help students understand the process of muscle contraction. A muscle contains many muscle fibers and each fiber contains a bundle of 4-20 myofibrils. Each fibril is striated and these striations are produced by the arrangement of thick and thin filaments, called actin and myosin. The contraction and relaxation of these actin and myosin filaments help muscles move.
