Tendon the endotendon running parallel to collagen fibres, with occasional branching transverse anastomoses. The internal tendon bulk is thought to contain no nerve fibres, but the epitenon and paratenon contain nerve endings, while Golgi tendon organs are present at the junction between tendon and muscle. Tendon length varies in all major groups and from person to person. Tendon length is, in practice, the deciding factor regarding actual and potential muscle size. For example, all other relevant biological factors being equal, a man with a shorter tendons and a longer biceps muscle will have greater potential for muscle mass than a man
Patellar tendon rupture Patellar tendon rupture Patellar tendon rupture is a tear of the tendon that connects the knee cap (patella) to the tibia. Often there is sudden onset of pain and walking is difficult. In a complete rupture the ability to extend that knee is decreased. A pop may be felt when it occurs. Injury to the patellar tendon generally requires a significant force such as falling directly on the knee or jumping from a height. Risk factors include patellar tendinitis, kidney failure, diabetes, and steroid or fluoroquinolone use. There are two main types of ruptures partial and complete. In most cases,
