Types of Muscle Tissue:
Skeletal Muscle:
Functions of skeletal muscle:
o Producing movement
o Maintaining posture and body position
o Supporting soft tissues
o Guarding body entrances and exits
o Maintaining body temperature
o Storing nutrients
Skeletal muscles contain:
o Skeletal muscle tissue (primarily)
o Connective tissues
o Blood vessels
o Nerves
Collagen fibers of epimysium, perimysium, and endomysium come together: At ends of
muscles to form:
o A tendon (bundle)
o Or aponeurosis (sheet)
To attach skeletal muscles to bones
Bundle within a Bundle (organization of muscle) & connective tissue wrappings
Skeletal muscles have three layers of connective tissue:
o Epimysium: [epi= above] a connective tissue wrapping around the bundle of bundles.
Layer of collagen fibers that surrounds the muscle
o Perimysium: Surrounds muscle fiber bundles (fascicles).
o Endomysium: Surrounds individual muscle cells (muscle fibers)
