The muscle physiology of skeletal muscle was observed by using electrical‚ physical‚ and neural stimulations of an isolated gastrocnemius muscle from Rana pipiens. The gastrocnemius receives signals from the action potentials of the sciatic nerve. The muscle contraction is caused by the binding of a neurotransmitter once the action potential reaches the neuromuscular junction. Stimulation of the muscle and the sciatic nerve allows for recording and measuring of these properties. We observed twitch

Muscle contractions happen when muscle fibers are stimulated‚ which can cause one of many types of contractions. Isometric contractions‚ which means that tension happens in the muscle but there is no change in muscle length‚ therefore there is no movement of the muscle itself. An example of Isometric contractions would be strength training‚ such as holding a weight still‚ which happens in the biceps brachii. The biceps brachii the gets more tension‚ but the muscle length stays the same. As for isotonic
