When a vertebrate skeletal muscle fibre is activated by a nerve impulse, an action potential
spreads from the endplate region along the whole fibre. It enters the transverse tubular …

It is well recognized that calcium (Ca) is an important regulatory element for many cellular
processes. In most eukaryotic cells a diverse array of Ca transporting systems functions to …

THE dihydropyridine (DHP) receptor purified from skeletal muscle comprises five protein
subunits (α 1, α 2, β, γ and δ) and produces Ca2+ currents that are blocked by DHPs1 …

Abstract INOSITOL 1, 4, 5-trisphosphate (InsP3) is an established mediator of intracellular
Ca2+ signals1 but little is known of the nature and organization of Ca2+ regulatory …

1. The Vaseline‐gap technique was used to record slow calcium currents and asymmetric
charge movement in single fibres of fast‐twitch muscles (extensor digitorum longus (edl) and …

1. Twitches, tetanic contractions and potassium contractures were recorded isometrically
from small bundles of rat soleus muscle fibres. 2. Solutions with reduced calcium …

1. The T-system, Triad Junction and Junctional" Feet'" 2. Proteins Associated with the
Junctional Foot Complex (a) The voltage sensitive molecule--a dihydropyridine receptor (b) …

The possible role of altered extracellular Ca2+ concentration ([Ca2+] o) in skeletal muscle
fatigue was tested on isolated slow-twitch soleus and fast-twitch extensor digitorum longus …

Primary cultures from enzymatically dissociated satellite cells of newborn rat skeletal
muscles enabled developmental in vitro studies of mechanical and electrical properties …

We aimed to investigate fatigue-induced changes in the spectral parameters of slow (SMF)
and fast fatigable muscle fiber (FMF) action potentials using discrete wavelet (DWT) and fast …
