The Membrane Components of Crustacean Neuromuscular Systems
I N T R O D U C T I O N Pharmacological data were among the evidence which led to the view that the over-all electrophysiological manifestations of different excitable membranes are composites of a number of independently assorting electrogenic processes (Grundfest, 1961 a, b). Subsequently available data (cf. Grundfest, 1963, 1966 a, b) have reenforced this view, that the excitable membrane is a
متن کاملThermal acclimation in a crustacean neuromuscular system.
1. Effects of temperature on the muscle fibre membrane and synapses of stretcher muscle preparations made from autotomized limbs of the Pacific shore crab (Pachygrapsus crassipes) were investigated. 2. Acclimation of the crabs to different temperatures modified properties of both muscle fibre membrane and synapses. 3. Increased temperature produced an increase in membrane potential of the muscl...
متن کاملPostsynaptic Inhibition at Crustacean Neuromuscular Junctions
The relative contribution of preand postsynaptic mechanisms to peripheral inhibition has been analyzed in the abdominal slow flexor muscles of crayfish and lobsters. The conductance of the muscle fiber membrane may be increased to five or more times its resting value by repetitive stimulation of the peripheral inhibitory axon, and this effect accounts for all of the attenuation exerted by the i...
متن کاملAssessing ultrastructure of crustacean and insect neuromuscular junctions.
Motor nerve terminals of arthropods provide excellent models for study of synaptic transmission, and their ultrastructure can be investigated in the same endings from which physiological recordings have been obtained. An experimental procedure for marking a recording site for subsequent ultrastructural analysis is described. The most commonly used procedure for ultrastructural analysis has been...
متن کاملCalcium and Facilitation at Two Classes of Crustacean Neuromuscular Synapses
The closer muscle of the crab, Chionoecetes, has at least two classes of excitatory neuromuscular synapses. In one class of synapses an action potential depolarizing the synaptic region releases much more transmitter if it has been preceded recently by another action potential. The other class of synapses shows this property, called facilitation, to a far lesser extent. Immediately after one co...
