There are three phases for muscle cell contraction: initiation of action potential in the sarcolemma‚ excitation-contraction coupling‚ and contraction‚ sliding of the myofilaments. ATP and calcium ions are two essential elements for muscle contraction. When ATP attaches to the myosin head‚ it gets hydrolyzed to ADP and Pi. Calcium ions bind to the troponin molecules and help expose the binding sites of actin filaments to allow for the attachment of the myosin heads. After the sliding of the myofilaments

A motor neuron‚ a nerve ending that is attached to a muscle fiber in Petzold’s huge bicep‚ sends a message to contract. This message goes to the neuromuscular junction‚ which is the connection between the actual nerve fiber and muscle fiber. As the message to contract reaches the terminals a neurotransmitter‚ a chemical messenger for the body‚ is released into the gap between the terminal end‚ and the sarcolemma and motor end plate called the synaptic cleft. The particular neurotransmitter is called
