Although well-adapted for the downward transmission of the body’s weight, the structure of the knee itself offers little resistance to the lateral displacement of the femur and tibia condyles during motion, so the knee’s stability depends on the strength of the surrounding ligaments and muscles...
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...
striated muscle; human biceps muscleThe structure of striated, or skeletal, muscle. Striated muscle tissue, such as the tissue of the human biceps muscle, consists of long fine fibres, each of which is in effect a bundle of finer myofibrils. Within each myofibril are filaments of the proteins...
KneeWe studied the MR imaging characteristics of the articular muscle of the knee, an important but seldom recognized structure of the distal thigh and knee.We used a 1.5-T system to prospectively evaluate the articular muscle of the knee in five healthy volunteers (10 knees); then we ...
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...
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...
It also discusses whether muscle deficits can be modified in knee OA and whether improvements in muscle function lead to improved symptoms and joint structure. It concludes with a discussion of exercise prescription for muscle rehabilitation in knee OA. 展开 ...
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...
Cerebral palsy (CP) is caused by a static lesion to the brain occurring in utero or up to the first 2 years of life; it often manifests as musculoskeletal impairments and movement disorders including spasticity and contractures. Variable manifestation
