How long is the latent period when a muscle twitch?

The latent period of a muscle twitch is the time between the stimulation of a motor neuron and the beginning of muscle contraction. It is typically around 10 milliseconds in humans. During this period, the action potential travels along the motor neuron, causing the release of acetylcholine at the neuromuscular junction. Acetylcholine binds to receptors on the muscle cell membrane, leading to the generation of an action potential in the muscle cell and ultimately muscle contraction.
