The Sliding Filament Theory
The steps of the sliding filament theory are: Muscle activation: breakdown of energy (ATP) by myosin. Before contraction begins, myosin is only associated with a molecule of energy (ATP), which myosin breaks down into its component molecules (ADP + P) causing myosin to change shape.
The cardiac muscle pumps blood
Smooth muscle aids digestion
It protects the organs
Smooth muscle ensures blood flow
The muscular system creates movement
Skeletal Muscle Tissue
It is a form of striated muscle tissue, which is under the voluntary control of the somatic nervous system. Most skeletal muscles are attached to bones by bundles of collagen fibers known as tendons.
Cardiac Muscle Tissue
Cardiac muscle tissue is an extremely specialized form of muscle tissue that has evolved to pump blood throughout the body. In fact, cardiac muscle is only found in the heart and makes up the bulk of the heart's mass.
Smooth Muscle Tissue
Smooth muscle generally forms the supporting tissue of blood vessels and hollow internal organs, such as the stomach, intestine, and bladder.
Structure of the Skeletal Muscle
Each skeletal muscle fiber is a single cylindrical muscle cell. An individual skeletal muscle may be made up of hundreds, or even thousands, of muscle fibers bundled together and wrapped in a connective tissue covering. Each muscle is surrounded by a connective tissue sheath called the epimysium.
