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
