NEURO-MUSCULAR TRNSMISSION IN INSECTS

Neuro-muscular control of dipteran flight.

Since the discovery of the myogenic nature of the main flight-muscle rhythm in flies and some other insects (Pringle, 1949; Roeder, 1951) there has been wide agreement that the nervous command to individual motor units must be one in which the significant aspect of the temporal code is the average frequency of nerve impulses and not detail of sequential pattern or the phase of each impulse (Wil...

Neuro-muscular Incoordination at the Cardia in the Newborn.

Hurst (1915) coined the word achalasia, i.e. absence of relaxation, to describe a neuro-muscular incoordination in the alimentary tract. Previously, Rolleston (1896) had suggested such an incoordination to explain some cases of dilatation of the oesophagus. The condition was then known as cardiospasm, a word introduced in 1882 by Mikulicz (1904). Earlier it was known as simple or idiopathic dil...

Neuro-Muscular Effects of Moderate Doses of Alcohol.

The Pharmacological Effects of Odonthobuthus doriae Scorpion Venom and Its Extracted Fractions on Neuro-Muscular Transmission

The effect of Odonthobuthos doriae (O.d) scorpion venom at 0/3, 1 and 3, 10 µg/ml concentrations were investigated on nerve-muscle transmission, using the Twitch tension technique. A concentration of 0.3 µg/ml caused a small change in the twitch height in response to indirect muscle stimulation, but higher concentrations (1, 3, 10 µg/ml) caused a transient augmentation in twitch response follow...
