Supracondylar process of the humerus Supracondylar process of the humerus The supracondylar process of the humerus (also known as an "avian spur") is a bony projection on the anteromedial aspect of the upper arm bone (humerus), about 5 cm above the medial epicondyle. It is directed downward, forward and medially pointing to the medial epicondyle. It is an anatomical variation which occurs in about one percent of all people. A fibrous band, Struthers ligament, may connect this process to the medial epicondyle. Supracondylar processes are usually asymptomatic, but may be palpable as a mass on the upper arm. They are most commonly found as an
Composition of the human body Composition of the human body Body composition may be analyzed in terms of molecular type e.g., water, protein, connective tissue, fats (or lipids), hydroxylapatite (in bones), carbohydrates (such as glycogen and glucose) and DNA. In terms of tissue type, the body may be analyzed into water, fat, muscle, bone, etc. In terms of cell type, the body contains hundreds of different types of cells, but notably, the largest "number" of cells contained in a human body (though not the largest mass of cells) are not human cells, but bacteria residing in the normal human gastrointestinal tract. Almost 99% of the
