Sheaths of connective tissue called epimysium
contain skeletal muscles and tendons.
Collagen is an important component of skeletal muscle, it is responsible for structure, organizing the muscle tissue at various levels, from the fascia and epimysium
to the perimysium and endomysium, being mainly composed of collagen type I and III (Calvi et al., 2012)
Twelve terms encompassing structures often called fascia have been proposed : dense connective tissue, areolar connective tissue, deep fascia, superficial fascia, interosseous membranes, intermuscular septae, epimysium
, perimysium, endomysium, periosteum, neurovascular tract, and intra- and extramuscular aponeuroses.
(4) Hematomas are described as intramuscular if the epimysium
contains the hematoma, or intermuscular if the fascia is ruptured.
A repeat fasciectomy of deep posterior compartment was performed, extended to muscle fascia (epimysium
) and tibialis posterior muscle.
This paper reviews the major intramuscular extracellular matrix (IM-ECM) structures (endomysium, perimysium and epimysium
) and their possible mechanical contributions to muscle functions.
In eight of the 10 patients, adequate mobilization of the biceps tendon was achieved by releasing adhesions, sectioning the lacertus fibrosus, performing relaxing incisions to the epimysium
, or applying traction to the distal biceps stump for several minutes and releasing the tourniquet.
Loin samples were carefully trimmed of all subcutaneous fat, epimysium
and peripheral muscles so that only the completely trimmed Longissimus dorsi muscle remained.
Fascicular fascia of the muscle comprises three distinct layers of IMCT: epimysium
surrounding whole muscles, perimysium separating fascicles or bundles of muscle fibers within the muscle, and endomysium covering the individual muscle fibers.
