42-2 - Muscular connective tissue
Organization of Connective tissues in
muscles
Muscles and muscle fibers are supported by
connective tissues
Sarcolemma is surrounded by
endomysium
-Myofibril is connected to the endomysium via special proteins
Groups of muscles fibers are covered by a
perimysium
Outer connective tissue sheath which envelops the
whole muscle is called
epimysium
Myotendinous Junction
– intricate connection
between muscle fibers and the connective tissues of the tendon
-Proteins reinforce the connection

Other connective tissues
1 Fasciae
Superficial fasciae:
loose tissue directly under the
dermis
Contributes to mobility of skin and act as an
insulator
Deep fasciae:
compacted and regularly arranged
collagenous fibers
Attach to bones and muscles
Retinacula:
localized transverse thickening of the
fasciae, attach to both ends of the bone
2 Aponeuroses:
sheets of dense, white and
compacted collagenous fibers
Attach directly or indirectly to the muscles and
distribute forces generated by the muscles to its
attachments
