“…Less direct support comes from the work of others on the muscle-cuticle junctions of arthropods (see, for example, Auber, 1963;Lai-Fook, 1967;Smith et al, 1969;Talbot et al, 1972). In this phylum, the muscle fibers terminate in digit-like extensions, distal to the terminal A-bands, in which the entire plasma membrane is subtended by an internal lamina.…”

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.

“…However, investigations on the ontogeny of osmoregulating tissues and its potential variations throughout development are still very limited (Hong, 1988;Bouaricha et al, 1994;Charmantier, 1998;Anger, 2001;Lignot and Charmantier, 2001). Among the few species in which the ontogeny of ion-transporting epithelia have been investigated by histological and/or electron microscopical studies are Farfantepenaeus aztecus (Talbot et al, 1972), Callianassa jamaicense (Felder et al, 1986), Penaeus japonicus (Bouaricha et al, 1994) and Homarus gammarus (Lignot and Charmantier, 2001). From these studies it appears that organs other than gills can also play a major role in ion-transport and that the location of epithelia involved in ion-exchange can change during development (reviewed by Charmantier, 1998).…”

The ontogeny of osmoregulation, the development of branchial transporting epithelia and the expression of the enzyme Na + /K + -ATPase were studied in Carcinus maenas (L.) obtained from the North Sea, Germany. Laboratoryreared zoea larvae, megalopae and young crabs were exposed to a wide range of salinities, and hemolymph osmolality was measured after 24·h exposure time (72·h in juveniles). Zoea I larvae slightly hyper-regulated in dilute media (10.2‰ and 17.0‰) and osmoconformed at >17‰.

“…Some microtubules in Artemia tendon cells appear to associate end-on with the apical membrane surface, as is the case in other species (Caveney, 1969;Talbot et al, 1972;Bubel, 1975). In comparison, microtubules in barnacle (Bubel, 1975) and brown shrimp (Talbot Fig.…”

“…Transalar tendon cells within Drosophila wing blades (Mogensen and Tucker, 1988;Mogensen et al, 1989;Fristrom et al, 1993) and Artemia exopodites (this study) connect apposing layers, as is true for the supporting epidermis of brown shrimp branchiostegite (Talbot et al, 1972). The gerbil organ of Corti possesses supporting cells, termed pillar and Dieters' cells, which enclose extensive bundles of microtubules and microfilaments (Bane et al, 2002), as well as intermediate filaments .…”

“…Similar structures in other species were given different names, including tonofibrils, tonofibrillae, and tonofilaments (LaiFook, 1967;Poodry, 1980;Fryberg et al, 1990;Reedy and Beall, 1993;Tucker et al, 2004). Rod-like elements are called intra-exoskeletal rods in barnacles, where they originate in membrane invaginations referred to as conical hemidesmosomes or hemidesmosomes (Bubel, 1975), muscle attachment fibers that arise in conical hemidesmosomes of Apterygota (Caveney, 1969), intracuticular fibers that form in conical hemidesmosomes of the larval brown shrimp (Talbot et al, 1972), or they are unnamed (Nakazawa et al, 1992). The folded basal membrane regions of Artemia tendon cells are characterized by electron-dense regions, as found commonly in other species (Talbot et al, 1972;Koulish, 1973;Bubel, 1975;Poodry, 1980;Fryberg et al, 1990;Nakazawa et al, 1992;Nakazawa and Ishikawa, 1993;Reedy and Beall, 1993), and they may mediate microtubule attachment.…”

Epidermally derived tendon cells attach the exoskeleton (cuticle) of the Branchiopod crustacean, Artemia franciscana, to underlying muscle in the hindgut, while the structurally similar transalar tendon (epithelial) cells, which also arise from the epidermis and are polarized, connect dorsal and ventral exopodite surfaces. To establish these latter attachments the transalar tendon cells interact with cuticles on opposite sides of the exopodite by way of their apical surfaces and with one another via basal regions, or the cuticle attachments may be mediated through linkages with phagocytic storage cells found in the hemolymph. In some cases, phyllopod tendon cells attach directly to muscle cells. Tendon cells in the hindgut of Artemia possess microtubule bundles, as do the transalar cells, and they extend from the basal myotendinal junction to the apical domain located near the cuticle. The bundled microtubules intermingle with thin filaments reminiscent of microfilaments, but intermediate filament-like structures are absent. Microtubule bundles converging at apical cell surfaces contact structures termed apical invaginations, composed of cytoplasmic membrane infoldings associated with electron-dense material. Intracuticular rods protrude from apical invaginations, either into the cuticle during intermolt or the molting fluid in premolt. Confocal microscopy of immunofluorescently stained samples revealed tyrosinated, detyrosinated, and acetylated tubulins, the first time posttranslationally modified isoforms of this protein have been demonstrated in crustacean tendon cells. Microfilaments, as shown by staining with phalloidin, coincided spatially with microtubule bundles. Artemia tendon cells clearly represent an interesting system for study of cytoskeleton organization within the context of cytoplasmic polarity and the results in this article indicate functional cooperation of microtubules and microfilaments. These cytoskeletal elements, either acting independently or in concert, may transmit tension from muscle to cuticle in the hindgut and resist compression when connecting exopodite cuticular surfaces.
