Structural dynamics of frog muscle during isometric contraction
Intensity fluctuation autocorrelation functions of laser light scattered by actively contracting muscle were measured at points in the scattered field. They were reproducible and showed characteristics which depended on the physiological state of the muscle and the parameters of the scattering geometry. The autocorrelation functions had large amplitudes and decay rates that varied significantly...
متن کاملVolume change and pressure development in muscle during contraction.
Volume change and pressure development in muscle during contraction. 1967.-Volume changes recorded in isometric and isotonic twitches of gastrocnemius muscle are similar to those recorded in sartorius muscle. The major differences are the greater difficulty in approaching isometric recording conditions in the gastrocnemius muscle and the possibility that a portion of the volume change could be ...

متن کاملChanges to 3 D muscle fascicle geometry during contraction
Muscle is a three dimensional (3D) entity with varying shape across the length of the muscle and changes shape during contraction. Changes in muscle shape can influence the orientation of the fascicles within the muscle [1]. Dissection studies examining 3D muscle fascicles architecture have reported regional variations in the fascicle architecture [2]. 2D ultrasound studies have shown that the ...
متن کاملChanges in Extraocular Muscle Volume During Ocular Duction
PURPOSE It has been tacitly assumed that overall extraocular muscle (EOM) volume is conserved during contraction and relaxation, yet this assumption has been untested up to now. We used high-resolution magnetic resonance imaging (MRI) to determine if total EOM volume changes during relaxation and contraction. METHODS Surface coil MRI in quasi-coronal planes was obtained in target-controlled, ...
