  1. 1. Muscle Thixotropy : Implications for Human Motor Control

    Author : Hans Axelson; Karl-Erik Hagbarth; Mikael Elam; Uppsala universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosciences; Motor control; Skeletal muscle; Thixotropy; History-dependent; EMG; Voluntary contractions; Neurovetenskap; Neurology; Neurologi;

    Abstract : Human skeletal muscles possess thixotropic, i.e. history-dependent mechanical properties. This means that the degree of passive muscle stiffness and resting tension is dependent on the immediately preceding history of contractions and length changes. READ MORE

  2. 2. Human muscle spindles : complex morphology and structural organisation

    Author : Jing-Xia Liu; William K. Ovalle; Umeå universitet; []
    Keywords : human; muscle spindle; intrafusal fiber; aging; biceps brachii; deep muscles of the neck; MyHC; mATPase; SERCA; anatomi; Human Anatomy; muscle spindIe;

    Abstract : Muscle spindles are skeletal muscle mechanoreceptors that mediate the stretch reflex and provide axial and limb position information to the central nervous system. They have been proposed to play a major role in the pathophysiology of muscle pain. READ MORE

  3. 3. Experimental studies of spinal mechanisms associated with muscle fatigue

    Author : Ivana Kalezic; Vito Enrico Pettorossi; Umeå universitet; []
    Keywords : muscle fatigue; monosynaptic reflex; presynaptic inhibition; recurrent inhibition; fusimotor system; Fos-immunoreactivity; referral pain; kirurgi; Surgery; Muscle fatigue; Monosynaptic reflex; Presynaptic Inhibition; Recurrent Inhibition; Fusimotor System; Referral Pain;

    Abstract : Muscle fatigue is ubiquitous in every day life.Muscle fatigue might be considered as an altered state of motor behaviour, which impairs motor performance. By contrast, muscle fatigue could also be considered a positive phenomenon, which protects muscle tissue from damage that might be incurred to it by overuse. READ MORE

  4. 4. Cross transfer effects after unilateral muscle overuse : an experimental animal study about alterations in the morphology and the tachykinin system of muscles

    Author : Yafeng Song; Per Stål; Sture Forsgren; Fawzi Kadi; Umeå universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICAL AND HEALTH SCIENCES; Triceps surae; overuse; contralateral; muscle; muscle fiber; MyHC; capillary; tachykinin; substance P; NK-1R; inflammation; anatomi; Human Anatomy;

    Abstract : Unilateral exercise can produce certain contralateral strength effects. Deleterious events can be cross-transferred as well, as illustrated by a strict symmetry in some chronic inflammatory diseases. READ MORE

  5. 5. Blood Flow in Human Skeletal Muscle : The Effect of Adrenaline and the Influence of a Small Muscle Injury

    Author : Torbjörn Vedung; Jan Henriksson; Jan Lundvall; Södersjukhuset Karolinska Institutet. Dept of Hand Surgery Dept of Physiology and Pharmacology; Karolinska Institutet; Karolinska Institutet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; adrenaline; blood flow; blood redistribution; ischemia; muscle injury; skeletal muscle; strain-gauge plethysmography; sympathetic tone; transmural pressure; 99mTechnetium clearance; tennis elbow; venous compliance; venous occlusion plethysmography; 133Xenon clearance; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; adrenaline;

    Abstract : A variety of vasoregulatory systems are involved in the complex control of blood flow inhuman skeletal muscle. The interaction between these systems where one system canoverride or modify the other makes blood flow regulation complicated. READ MORE
