smooth muscle - muscle tissue that does not appear striated under the microscope; has the form of thin layers or sheets muscle system, muscular structure, musculature - the muscular system of an organism tonicity, tonus, tone - the elastic tension of living muscles, arteries, etc. that facilita...
It is the origin of the straight head of the rectus femoris muscle, a flexor of the thigh at the hip, and an extensor of the knee. From: Human Osteology (Third Edition), 2012 About this pageSet alert Also in subject areas: Immunology and Microbiology Medicine and DentistryDiscover other ...
When the muscles of the quadriceps femoris group contract, they extend the knee joint, straightening the leg. How do the bones of the human skeleton move? Skeletal muscles contract and relax to mechanically move the body. Messages from the nervous system cause these muscle contractions. The whole...
9 suggest that, during walking, old adults’ ankle extensors work near their capacity limits and at almost twice the greater relative level compared to knee or hip extensors; however, the recent work of Spinoso et al.11 reported a much higher effort for the knee extensors (>90%) compared...
The goal was to quantify the influence of the myofascial structures on excursions and moment arms of knee muscles to attempt explaining the above-mentioned post-surgical observations. Hamstring harvesting procedures were performed by a senior orthopaedic surgeon on seven lower limbs from fresh-frozen ...
The popliteus muscle is the most important structure on the lateral side of the knee. In the early years of this century this was studied by many authors [for instance, in the fundamental monography...doi:10.1007/978-3-642-72782-5_10C. Fabbriciani...
Titin is the largest known protein with a structure that is highly elastic, acting like a giant multifunctional spring (Fig. 4.1.2a). Thus, it is strongly linked to passive muscle tension, sarcomere integrity, and the efficiency of contraction (Krüger and Kötter, 2016; Hessel et al., 20...
Smooth muscle is located in the walls of hollow internal structures in the body, like the arteries, intestines, bladder, and iris of the eye. They tend to circle the structure and when they contract, the hollow structure is squeezed. These muscles are involuntary (we cannot control their func...
sectional differences in thigh muscle status between knees with an early radiographic stage of knee OA vs contralateral knees without RKOA (within-person comparison), and on 2-year changes in muscle ACSAs (the dependent variable) of knees with and without early RKOA (the independent variable)....
