Muscle Physiology and Modeling
Because they are so important for survival, muscles have evolved many complex features that enhance their strength, speed, efficiency and controllability. The model presented here consists of quantitative functions that represent each of the anatomical structures and physiological processes that underlie such features in typical mammalian skeletal muscles. These include the processes of recruit...
متن کاملSleep Physiology: Setting the Right Tone
Humans prone to cataplexy experience sudden losses of postural muscle tone without a corresponding loss of conscious awareness. The brain mechanisms underlying this debilitating decoupling are now better understood, thanks to a new study using cataplectic mice.
متن کاملSmooth Muscle Tone
The objective of this study was to elucidate the mechanisms associated with the reciprocal relation between magnesium and calcium on vascular smooth muscle tone in bovine pulmonary artery and vein. Rapid removal of magnesium from Krebs-bicarbonate medium used to bathe isolated rings of precontracted artery or vein caused transient endotheliumand calciumdependent relaxation and cyclic GMP accumu...
متن کاملResolved lower limb muscle tone abnormalities in children with HIV encephalopathy receiving standard antiretroviral therapy.
BACKGROUND This short report arose from a follow-up study of children previously diagnosed with human immunodeficiency virus (HIV) encephalopathy and spastic diplegia and is among the first to describe that increased lower limb muscle tone in children with a confirmed HIV encephalopathy diagnosis may resolve over time in some cases. RESULTS Of 19 children previously diagnosed with HIV encepha...
متن کاملMuscle Physiology and Contraction Theories
The structural basis of current contraction theories is the double array of thick and thin myofilaments revealed by the electron microscope. The physiologic properties that characterize the contractile process are natural consequences of this structure if (a) during shortening the 2 sets of filaments move relative to each other and (b) the flux of chemical energy through the contractile mechani...
