An invertebrate smooth muscle with striated muscle myosin filaments.
Muscle tissues are classically divided into two major types, depending on the presence or absence of striations. In striated muscles, the actin filaments are anchored at Z-lines and the myosin and actin filaments are in register, whereas in smooth muscles, the actin filaments are attached to dense bodies and the myosin and actin filaments are out of register. The structure of the filaments in s...
متن کاملSurface features of striated muscle. I. Guinea-pig cardiac muscle.
A general survey of guinea-pig myocardium was undertaken using the freeze-etch technique. Replicas of myocardial cell membranes were obtained. These showed an ordered array of pits or stumps situated at Z levels. The pits are interpreted as the apertures of the transverse tubules (T-tubules) seen from outside the cell, and the stumps as the remnants of the T-tubules remaining attached to the ce...
متن کاملStriated muscle-type tropomyosin in a chordate smooth muscle, ascidian body-wall muscle.
Body-wall muscle tropomyosin (Tm) of a marine chordate, the ascidian Ciona intestinalis, was studied by protein and cDNA clone analyses. Our results indicate that body-wall muscle of Ciona contains one major Tm isoform encoded by a single gene. Unexpectedly, the sequence of this Tm resembles vertebrate-striated muscle Tm isoforms, rather than those of smooth muscle or nonmuscle tissues, despite...
متن کاملHalothane increases smooth muscle protein phosphatase in airway smooth muscle.
BACKGROUND Halothane relaxes airway smooth muscle, in part, by decreasing the force produced for a given intracellular [Ca(2+)] (i.e., Ca(2+) sensitivity) during muscarinic stimulation, an effect produced by a decrease in regulatory myosin light-chain (rMLC) phosphorylation. The authors tested the hypothesis that halothane reduces rMLC phosphorylation during muscarinic stimulation at constant i...
متن کاملTumors of striated muscle.
Three benign forms of muscle tumors and three variants of rhabdomyosarcoma are discussed from the point of view of their histology and behabior. Recent combined modality therapy has significantly improved the prognosis in at least the embryonal form of rhabdomyosarcoma.
