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
Achilles tendon rupture to rupture. The use of quinolone antibiotics can cause several forms of tendinitis and tendon rupture, including rupture of the Achilles tendon. The risk is higher in people who are older than 60, who are also taking corticosteroids, or have kidney disease; it also increases with dose and taking them for longer periods of time. As of 2016 the mechanism through which quinolones cause this, was unclear. The Achilles tendon is the strongest and thickest tendon in the body, connecting the gastrocnemius, soleus and plantaris to the calcaneus. It is approximately 15 centimeters (5.9 inches) long and begins near the
