MUSCLE There are 3 main types of muscles   Skeletal Smooth Cardiac Site Attached to skeleton Viscera except heart Heart Muscle fibers Striated Innervation Somatic nerves Autonomic nerves Action voluntary Involuntary

Attachment of skeletal muscle: Skeletal muscles: Attachment of skeletal muscle: Origin: it is the beginning of the muscle, it is usually proximal & fixed. Insertion: it is the end of the muscle, it is usually distal & movable. Forms of attachments: Fleshy: the regular fleshy nature of the muscle. Tendon: cylindrical cord like fibrous tissue. Aponeurosis: flat sheet like fibrous tissue. Raphe: meeting of 2 muscles (usually in midline), in the form of a mixture of fleshy & tendinuous fibers.

Types of skeletal muscles: Features Parallel The muscle fibers are parallel from origin to insertion Fusiform Parallel muscle fibers with central dilatation Triangular The fibers attaches by a wide origin & narrow insertion Circular The fibers forms a circle Pennate Unipennate The fibers attaches obliquely to the tendon from one side Bipennate The fibers attaches to the tendon from 2 sides Multipennate Union of many bipennate parts Circumpennate Circular arrangement of multipennate
