Through a comprehensive assessment of muscle histology and ex vivo function, mathematical modelling and neuronal tracing, we demonstrate regional heterogeneities at the level of the MN, muscle fibre type composition and oxygen delivery kinetics of …

Mar 1, 1998 · The extensor digitorum longus muscle (EDL) of the rat hindleg consists of four heads. The heads are named after their insertions on the digits of toes II, III, IV and V. The EDL heads share a proximal tendon and aponeurosis, but …

The present work shows that identical slow pattern stimulation differentially affects MyHC expression in regenerating muscle fibres in SOL and EDL and within EDL of adult rats. After 27 days of such stimulation, SOL expressed 87% and EDL only 13% of slow type 1 MyHC.

In skeletal muscle, excitation leads to increased [Na +] i, loss of K +, increased [K +] o, depolarization, and Cl − influx. This study quantifies these changes in rat extensor digitorum longus (EDL) muscles in vitro and in vivo using flame photometric determination of Na + and K + and 36 Cl as a tracer for Cl −.

For all experiments, isolated EDL muscles were mounted vertically at optimal muscle length for isometric twitch force production (L0) on the dynamic muscle puller with the proximal end fixed and...

The purpose of the present study is to investigate the origin of mechanical interactions between the rat extensor digitorum longus (EDL) muscle and the grouped tibialis anterior and extensor hallucis longus muscles (TA+EHL).

Jul 7, 1998 · Denervated fast extensor digitorum longus (EDL) muscles of adult rats were stimulated electrically for up to 4 months with a ‘slow’ pattern resembling the activity in soleus (Sol) motor units and examined with antibodies against myosin heavy chains (MHCs).

Nov 21, 2021 · Through a comprehensive assessment of muscle histology and ex vivo function, mathematical modelling and neuronal tracing, we demonstrate regional heterogeneities at the level of the MN, muscle fibre type composition and oxygen delivery kinetics of the rat extensor digitorum longus (EDL) muscle.

Individual fibers of prospective fast (extensor digitorum longus; EDL) and slow (soleus) muscles of rats have been analyzed to determine the profiles of key energy-generating enzymes at successive stages of postnatal development.

Force transmission in rat anterior crural compartment, containing tibialis anterior (TA), extensor hallucis longus (EHL) and extensor digitorum longus (EDL) muscles, was investigated. These muscles together with the muscles of the peroneal compartment were excited maximally.
