Thorn (letter) Thorn or Ã¾orn (Ã¾, Ã¾) is a letter in the Old English, Gothic, Old Norse and modern Icelandic alphabets, as well as some dialects of Middle English. It was also used in medieval Scandinavia, but was later replaced with the digraph th, except in Iceland, where it survives.
Hip internal rotation exercises are designed to strengthen the groin, or adductor muscles of the inner thigh. These muscles bring the legs together while the outer hip muscles, called abductors, pull the legs apart. Muscular strength and flexibility imbalances can occur between the outer hip muscles and the groin muscles. Exercises can promote internal hip rotation to correct these imbalances.
Calf (leg) The calf (Latin: sura) is the back portion of the lower leg in human anatomy. The muscles within the calf correspond to the posterior compartment of the leg. The two largest muscles within this compartment are known together as the calf muscle and attach to the heel via the Achilles tendon. Several other, smaller muscles attach to the knee, the ankle, and via long tendons to the toes.
