The chemical message, a neurotransmitter called acetylcholine, binds to receptors on the outside of the muscle fiber. That starts a chemical reaction within the ...

The Ca ions produce attractive forces to act between actin and myosin filaments, causing them to slide alongside each other, leading to the contractile process.

A single motor neuron is able to innervate multiple muscle fibers, thereby causing the fibers to contract at the same time. Once innervated, the protein ...

The motor nerve fiber makes synaptic contacts with the muscle fiber at the neuromuscular junction. The neuromuscular junction is composed of three cellular ...

A skeletal muscle fiber contracts as the thin filaments are pulled and then slide past the thick filaments within the fiber's sarcomeres.

The process of muscle contraction begins at the site where a motor neuron's terminal meets the muscle fiber—called the neuromuscular junction (NMJ). Every ...

In all muscle cells, contraction depends on a rise in cytosolic calcium. Signaling pathways control the release of calcium from intracellular stores, as well ...
