“…It completely invests the muscle fibre, except at the few sites where muscle satellite cells are found interposed between basement membrane and muscle plasma membrane (Katz, 1961;Mauro, 1961). At each end of a muscle fibre the basement membrane connects with the tendon material (Hanak & Bock, 1971). In the region of the motor end-plate, the basement membrane invests the synaptic cleft and post-synaptic membrane folds, and is continuous with a similar material which surrounds the nerve/Schwann cell complex.…”

SUMMARYI. Frog cutaneous pectoris nerve-muscle preparations were incubated with collagenase and protease and examined with electrophysiological and electron microscopic techniques.2. The physiological properties and intracellular ultrastructural appearance of individual muscle and nerve cells were not affected by the enzyme treatment. However, neuromuscular transmission and the morphology of the nerve-muscle junction were altered.3. Collagenase produced an irreversible loss of activity of end-plate cholinesterase and a partial loss of stainable 'synaptic cleft material'. 4. Protease produced these changes and, in addition, the entire basement membrane was digested, which led to 'synaptic disjunction' of nerve terminals and muscle end-plates.

“…Ultrastructural studies on a number of species have revealed that the terminations of skeletal muscle fibers are characterized by longitudinal foldings of the surface membrane that produce processes that take the form of either extensions or invaginations (for example, see Eisenberg and Milton, 1984;Hanak and Bock, 1971;Ishikawa, 1965;Ishikawa et al, 1983;Tidball, 1983;Trotter et al, 1981). Studies on this region can be broadly divided into two categories: One is concerned with the molecular structure that specializes the region for force transmission; the other focuses on quantitative and three-dimensional aspects of the region.…”

Transmission of contractile tension from skeletal muscle fibers to connective tissue elements is thought to occur at the muscle-tendon junctions, specialized regions at the extreme ends of the fibers. Previous work has suggested that the structure of this region may be quantitatively modified to match the contractile properties of the fibers. Using scanning electron microscopy, transmission electron microscopy, and stereological analysis, we have analyzed the three-dimensional structure, and have quantitatively compared the muscle-tendon junctions, of slow and fast fibers of the anterior (ALD) and posterior (PLD) latissimus dorsi muscles of the chicken. The ends of ALD and PLD fibers are found to be structurally different in some respects but to be similar with respect to their surface specializations, which are believed to function in the transmission of tension. Quantitative analysis of these specializations indicates that, when referred to similar cross-sectional areas of myofilaments, the fast fibers of the PLD have approximately 40% more surface area devoted to force transmission than do the slow fibers of the ALD. These observations are consistent with the idea that the amount of cell surface specialized for force transmission is related to the functional properties of the muscle fiber.

“…A great deal of recent research under the electron microscope shows that at the MTJ the end of muscle fiber has many processes and invaginations of the sarcolemma, which are covered by the basement membrane (Gelber et al, 1960;Schwarzacher, 1960b;Ishikawa, 1965;Matter and Forssmann, 1967;Hanak and Bock, 1971;Ajiri et al, 1978). The space between the sarcolemma and the basal lamina (lamina densa) is called the lamina rara (Ajiri et al, 1978).…”
