The three stages of muscle cell contraction are excitation, excitation-contraction coupling, and contraction. During excitation, an action potential triggers the release of calcium ions from the sarcoplasmic reticulum. In excitation-contraction coupling, calcium binds to troponin, allowing for cross-bridge formation between actin and myosin. Finally, in the contraction stage, myosin heads pull on actin filaments, causing muscle contraction.

The short period following the arrival of a stimulus at a skeletal muscle cell is called the latent period. During this time, the muscle cell is preparing for contraction by releasing calcium ions and activating the contractile proteins.
The first phase after a stimulus in a muscle contraction is excitation-contraction coupling. This involves the transmission of the action potential along the sarcolemma and the release of calcium ions from the sarcoplasmic reticulum.
The phase between the stimulus of a muscle and the shortening of the muscle is called the latent phase or latent period. During this phase, the muscle is receiving the signal to contract, but actual muscle shortening has not yet occurred. This period is important for the muscle fibers to prepare and generate enough force for contraction.
Joseph Black studied chemistry, specifically focusing on the properties of gases and the concept of latent heat. He is known for his discovery of carbon dioxide and his development of the concept of latent heat in chemical reactions.
Latent energy in a fuel refers to the energy released during the combustion process of the fuel. This energy is stored within the chemical bonds of the fuel and is released in the form of heat when the fuel is burned. It is a crucial factor in determining the energy content and efficiency of a fuel.
