, reduce type II force, so testosterone generally may favor type II and inhibit type I functions? Overall, the effects of testosterone deficiency are exacerbated in males compared with females. Testosterone deficiency leads to a decline in body mass, a decrease in fast-twitch fiber diameter, a...
biochemical, morphological, and physiological properties. There are three basic muscle fiber types, Type I, or slow twitch fibers which are aerobic and are considered our endurance fibers, Type IIa, or intermediate Fast twitch fiber type which exhibit both aerobic...
muscle fiber (redirected fromMuscle fibers) Thesaurus Medical Encyclopedia Related to Muscle fibers:muscle contraction,fast twitch muscle fibers muscle fiber n. A muscle cell, especially one of the cylindrical, multinucleate cells that make up skeletal muscles and are composed of numerous myofibrils tha...
the measured force during voluntary contraction showed good resemblance with the deformation curves. Ultrasound measurements of muscle deformation can show active and passive muscle functions. Eccentric contractions imply active muscle elongation, and concentric contractions imply active muscle contraction. Passiv...
An enzyme-histochemical study (ATPase stain) was done simultaneously in 19 rats two weeks after denervation in order to determine the proportion of 1, 2a+2b, and 2c muscle fiber types in each muscle. The findings are as follows: (1)the firing rates of FP were different in each type of...
In addition to serving as a component of the cross-bridge, the myosin head also functions as adenosine triphosphatase (ATPase), allowing the head to cleave ATP and energize contraction (Fig. 15.5). Actin filaments are composed of three protein components: actin, tropomyosin, and troponin (Fig....

The E2F transcription factor is a key cell cycle regulator. However, the inactivation of the entire E2F family in Drosophila is permissive throughout most of animal development until pupation when lethality occurs. Here we show that E2F function in the a
