Muscle Twitch Definition An action potential in a skeletal or oculomotor motoneuron axon produces, after neuromuscular synaptic transmission, a propagating action potential in the innervated muscle fibers followed by an increase in intracellular calcium. The calcium activates the actin-myosin cross-bridges ...

Anatomy: The muscle crosses three joints: the sternoclavicular, acromioclavicular, and glenohumeral joint. The pectoralis major muscle is a thick, fan-shaped muscle. Medially it originates from four separate attachments: the clavicular fibers, which attach to the anterior surface of the manubrium an...

Type I muscle fibres are slow-twitch. They are red in colour due to large volumes ofmyoglobin. As a result, they have high levels of Mitochondria and oxygen. This makes them very resistant to fatigue and good at aerobic metabolism. Therefore, they produce repeated low-level contractions by ...

The means by which all types of muscles contract is thought to be generally the same, although muscles are classified as phasic, or fast twitch, and tonic, or slow twitch, to differentiate between the various lengths of time a muscle may require to move in response to stimulation. Striated ...
