Synonyms: Adduction of hip, Adductio coxae. The gluteus maximus muscle exhibits four actions on the hip joint; extension, external rotation, abduction and adduction of the thigh.

The triceps brachii (TB) is the only muscle that lies along the posterior humerus, and its role in elbow extension has been the topic of investigation for many decades. The TB research has also included subjects such as strength training, effects of aging, training adaptions, etc. Z4DC.what are the functions of the triceps
