Thermal dependence of passive electrical properties of lizard muscle fibres.
1. The thermal dependence of passive electrical properties was determined for twitch fibres from the white region of the iliofibularis (IF) muscle of Anolis cristatellus (15-35 degrees C) and Sceloporus occidentalis (15-40 degrees C), and for twitch fibres from the white (15-45 degrees C) and red (15-40 degrees C) regions of the IF of Dipsosaurus dorsalis. These species differ in thermal ecolog...
متن کاملMuscle fibres and efferent nerves in a crustacean receptor muscle
The accessory flexor muscle of the crab myochordotonal organ consists of two kinds of muscle-fibres. In one type the fibrillar material has a uniform punctate appearance in cross-section. The Z bands are often broken across the fibre width and are spaced 2 to 3/n apart. These resemble the 'Fibrillenstruktur' muscle of vertebrates. In the second fibre type the fibrillar material appears as large...
متن کاملThe electrical properties of a crustacean sensory dendrite.
1. The input properties and the response to stretch of a coxal receptor, the S fibre of the crab Scylla serrata, were studied using two and three intracellular microelectrodes. 2. In the relaxed receptor the transmembrane potential ranged from about -60 to -70 mV, and the input resistance, RT, from 1 to 3 M omega. The input IV relationship, studied by injecting slow-rising current ramps, was no...

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
15 صفحه اولLocalization and Properties of the Cholinesterase in Crustacean Muscle
Cholinesterase (ChE) activity is present in crustacean muscle extracts. However, since acetylcholine (ACh) is not a neuromuscular transmitter in these animals, the role and exact localization of ChE was unknown. The histochemical localization of the enzyme was studied in whole muscle and in the sarcoplasmic reticulum fraction of the extract, 50-microm frozen sections of glutaraldehyde-fixed cra...
