Document Summary

Comprises largest groups of tissue in the body. Appears throughout the body systems as components of hollow organs and tubes. Origin: muscle attachment to the none at the stationary end (head) Prime mover (agonist: muscles that provides most of the force for a given movement. Antagonist muscles: muscles that produce opposite movements. Synergistic muscle: muscles that work together to produce the same movement. Structure of skeletal muscle: muscle consists of a number of muscle fibres lying parallel to one another and held together by connective tissue. Single skeletal muscle cell is known as a muscle fibre: multi-nucleated. Macroscopic structure: connective tissue: muscle is composed of muscle tissue and connective tissue, multiple layers of connective tissue. 3 types of connective tissue extensions of deep fascia (most superficial to deep) Layer of connective tissue around entire muscle deep to superficial fascia. Connective tissue that surrounds a bundle of muscle fibres (muscle cells) Actin and myosin are often called contractile proteins.
