Potassium Retention in Crab Nerve
نویسنده
چکیده
Spectrophotometric determinations of the potassium content of small volumes of sea water brought into contact with crab nerves over half-hour intervals demonstrate (a) a continuous loss of potassium from the fibers while at rest in oxygen; (b) an appreciable increase in the leakage during anoxia; (c) a reabsorption of potassium during postanoxic recovery; and (d) a reduction in the amplitude of the anoxic and postanoxic changes in the presence of glucose.

Potassium Movement in Relation to Nerve Activity
The depolarization of crab nerve during repetitive stimulation is unaffected by the presence of glucose or by an increase in the calcium content of the medium. It is increased in both amplitude and rate by veratrine; in the presence of this alkaloid mixture the rate but not the magnitude of the depolarization is increased by an elevation in the calcium concentration. Repolarization following st...
متن کاملThe Potassium and Water Contents of Cat Nerves as Affected by Stimulation
A LOSS of potassium from unmyelinated crab nerve has been reported by Cowan (‘34) and has been recently confirmed with somewhat improved technique by Young (‘38). Vogt (‘36) has reported losses of K from the cervical sympathetic ganglion during stimulation. No observations have apparently been made on myelinated nerves except two experiments (Fenn, ‘34) on frog nerves which showed only losses o...
متن کاملThe Effect of Stimulation on the Potassium Content of Limulus Leg Nerves
THE RESULTS of experiments on the potassium loss in nerves during stimulation have led to no definite general conclusion. Fenn (‘38) working with the myelinated nerves of cats and frogs obtained no significant loss of potassium. Cowan ('34) using the unmyelinated nerves of the spider crab, Maia squinado, obtained an appreciable loss of potassium during fZteen minutes of stimulation. His method,...
متن کاملElectrophysiological analysis of potassium and sodium movements in crustacean nervous system.
1. An electrophysiological method was used to estimate the half-times for sodium and potassium entry to, and efflux from, the extra-axonal space in peripheral nerve and central nervous connectives of two species of crustacean. Results from crab (marine) and crayfish (fresh water) were qualitatively similar. 2. Peripheral nerve showed no evidence for diffusion barriers, potassium entry and efflu...
متن کاملDifferential Responses of Crab Neuromuscular Synapses to Cesium Ion
Excitatory postsynaptic potentials (EPSP's) generated in crab muscle fibers by a single motor axon, differ in amplitude and facilitation. Some EPSP's are large at low frequencies of stimulation and show little facilitation; others are smaller and show pronounced facilitation. When K(+) is replaced by Cs(+) in the physiological solution, all EPSP's increase in amplitude, but small EPSP's increas...
