1. Slow twitch fibres (Type I): Slow twitch fibres contract slowly but can contract repeatedly over long periods. They have a good blood supply, hence they are âred fibresâ, and are suited to endurance activity using the aerobic energy system which relies on oxygen from the blood for the supply of energy.
Muscle tissue is responsible for most types of body movement. I. Types of muscle: A. Striated muscle-skeletal musculature, striated in appearance under microscope. Cells are unbranched and are multinucleate syncytia.These muscles are capable of voluntary, quick, forceful contractions.s a result, neurotransmitters have to diffuse across this connective tissue layer and onto the plasmalemma of the smooth muscle cells in order to initiate the action potential that causes contraction. This is another reason for the slower contraction of smooth muscle cells.
