Modeling Mouse Soleus Muscle Contraction
2020 42nd Annual International Conference of the IEEE Engineering in Medicine & Biology Society (EMBC), 2020Models of muscle contraction are typically based on a measured force-velocity relation embodied as Hill's contractile element [1]. Adopting a particular force-velocity relation dictates the muscle's mechanical properties. Dynamic crossbridge based models, such as Huxley's [2], typically focus on ultrastructural mechanics.

Ultrasound Imaging of Torn Soleus Muscle
PM&R, 2015Figure 1. In comparison with the normal side, the left calf appeared markedly swollen, without noticeable ecchymosis. A 51-year-old man was referred for ultrasound (US) examination because of persistent left calf swelling for 3 months. The swelling developed abruptly after he had stumbled against a stone, sustaining an inversion injury to his ankle. He

Venous drainage of the soleus muscle
Surgical and Radiologic Anatomy, 2008Soleus veins have been implicated as the site for deep venous thrombosis initiation. Detailed anatomic knowledge is required for the early diagnosis using non-invasive ultrasound techniques. In the present work, we describe the anatomy of the veins that emerge from the ventral face of the soleus muscle.

Frequency response of human soleus muscle
Journal of Neurophysiology, 19761. The properties of human soleus muscle were studied by systems analysis. Single stimulus pulses and random stimulus pulse trains were applied to a branch of the nerve to soleus muscle and the resultant tension fluctuations were recorded. 2. The frequency-response function between stimulus pulses and tension conforms to that of a second-order, low ...

Acta orthopaedica Belgica, 1994
An asymptomatic soft tissue mass in the distal calf region was examined with magnetic resonance. The diagnosis of an accessory soleus muscle was made using the tissue and topographical characteristics.

MR Imaging of Accessory Soleus Muscle
Journal of Computer Assisted Tomography, 1990The accessory soleus muscle is an unusual anatomical variant that may present as a mass in the distal calf or medial ankle region. On both magnetic resonance (MR) and ultrasound, this variant has appearances similar to adjacent normal muscle. The diagnosis can be strongly suggested by typical location and by both echo texture and MR signal pattern of ...

The Cross-Leg Soleus Muscle Flap
Annals of Plastic Surgery, 2000Reconstruction of the lower limb can be a difficult problem, especially when located over the lower third of the leg, or when a large soft-tissue defect exists. When local flap coverage is not possible, a distant flap--free or pedicled--is indicated. There are, however, circumstances that preclude the use of a free flap, and in these situations cross ...

String mitochondria in mouse soleus muscle
Microscopy Research and Technique, 2012Red myofibers in mouse soleus muscle have two spatially distinct populations of mitochondria: one where these organelles are disposed in large clusters just inside the sarcolemma and the other situated between the myofibrils. In most cases, the interfibrillar mitochondria (IFM), which are much smaller than the subsarcolemmal ones (SSM), are arranged as

Rat soleus muscle ultrastructure after hindlimb suspension
Journal of Applied Physiology, 1990The aim of the present investigation was to determine, by quantitative electron microscopy, the effects of a 5-wk tail-suspension period on rat soleus muscle ultrastructure. A marked decline (-60%) in muscle mass occurred. The mean fiber cross-sectional area decreased to a greater extent (-75%) than the capillary-to-fiber ratio (-37%), leading to a ...

Soleus muscle contractile properties in hypertensive rats
American Journal of Physiology-Regulatory, Integrative and Comparative Physiology, 1994Three types of hypertensive rats, and their normotensive controls, were assessed to determine the effects of high blood pressure on the contractile and fatigue properties of the soleus muscle. Spontaneously hypertensive rat (SHR) soleus developed less contractile force and fatigued more rapidly than normotensive Wistar-Kyoto (WKY) controls.
