Arrangement and density of junctional feet in crayfish muscle fibres.
نویسندگان
چکیده
Junctional feet in tubulo-reticular junctions of crayfish muscle fibres are arranged tetragonally with a centre-to-centre spacing of 30-34 nm. The resulting density of 860-1110 feet per 1 micron 2 of the junctional membrane is similar to that reported for other animal species. Using data of a previous stereological study, there are 150-190 feet per 1 micron 2 of the total T-tubule surface and 6000-7800 feet per 100 microns 3 of the fibre volume.

Disintegration of junctional feet in crayfish muscle fibres kept in vitro.
The significance of junctional feet (Franzini-Armstrong 1971) for excitation-contraction (E-C) coupling is suggested by their location in the gap separating the T-system from the sarcoplasmic reticulum (SR). Until now, however, no specific treatment for selectively disrupting junctional feet has been known and the direct evidence relating the presence of feet to the transfer of signals across t...
متن کاملStructure and electrical properties of eye muscles in cave- and surface-dwelling crayfishes.
The morphologies and passive electrical parameters of fibres in two eye muscles of a surface- and a cave-dwelling crayfish were compared. In the cave-dwelling form the muscles contained fewer fibres, of less diameter, and hence had a smaller cross-sectional area. Current-voltage relationships were similar in both species. Input resistance was higher in the cave-dweller, but the difference was n...
متن کاملCalcium channels in crayfish muscle fibre fragments studied by means of the Vaseline gap technique.
Calcium currents in crayfish muscle fibres were studied by means of the vaseline gap voltage clamp technique. Overlapping potassium currents were fully suppressed using fibre fragments equilibrated in K+-free intracellular solution. The design of the recording chamber tailored to crayfish muscle fibres is described in detail. Ca currents recorded has a two-component time course. The transient (...
متن کاملPreparation and morphology of sarcoplasmic reticulum terminal cisternae from rabbit skeletal muscle
We have developed a procedure to isolate, from skeletal muscle, enriched terminal cisternae of sarcoplasmic reticulum (SR), which retain morphologically intact junctional "feet" structures similar to those observed in situ. The fraction is largely devoid of transverse tubule, plasma membrane, mitochondria, triads (transverse tubules junctionally associated with terminal cisternae), and longitud...
متن کاملFreeze Fracture of Skeletal Muscle from the Tarantula Spider
The structure of the membranes of sarcoplasmic reticulum (SR), tubular (T) system, and sarcolemma has been studied by freeze fracture in leg muscles of the Tarantula spider. Two regions of the sarcoplasmic reticulum can be differentiated by the distribution of particles on the fracture faces: a junctional SR, at the dyads, and a longitudinal SR, elsewhere. The dyads are asymmetric junctions, th...
