WebbGastrointestinal physiology is the branch of human physiology that addresses the physical function of the gastrointestinal (GI) tract. The function of the GI tract is to process ingested food by mechanical and chemical means, extract nutrients and excrete waste products. The GI tract is composed of the alimentary canal, that runs from the mouth ... Webb1. Muscle activation: The motor nerve stimulates an action potential (impulse) to pass down a neuron to the neuromuscular junction. This stimulates the sarcoplasmic reticulum to release calcium into the muscle cell. 2. Muscle contraction: Calcium floods into the muscle cell binding with troponin allowing actin and myosin to bind.

WebbThe contraction of a muscle causes the release of ATP, which is then converted into ADP. The beginning of a muscle contraction is caused by calcium's interaction with actin's troponin. The threshold of 30 mV is reached when sodium enters the sarcolemma, which causes the threshold to be reached.
