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.
