CONNECTIVE TISSUES AND FASCICLES
Insertion
Bony attachment to the mobile end of the muscle
Perimysium
Connective tissue surrounding a fascicle
Endomysium
Loose Connective tissue surrounding a muscle fiber
MULTIPENNATE MUSCLE
Shaped like a bunch of feathers with quills converging on a single point Generate the most force due to the increased number of muscle fibers eg. Deltoid has 3 muscles
Origin
The attachment of a muscle tendon to a stationary bone or the end opposite the insertion
Belly
Thickest region between the Origin and the Insertion
Fascia
a band or sheet of fibrous connective tissue that covers, supports, and separates muscle
sphincter muscle (voluntary)
a ring of muscle that contracts to close an opening such as the anus
Tendons
bridge the gap between muscle ends and bony attachment
Fascicles (UNIT)
bundles of muscle fibers wrapped in perimysium •Carry larger nerves and blood vessels, and stretch receptors
Epimysium
surrounds entire muscle
fusiform muscles
thick in the middle and tapered at each end
parallel muscles
uniform width and parallel fascicles
