The
antebrachial fascia (
antibrachial fascia or
deep fascia of forearm) continuous above with the
brachial fascia, is a dense, membranous investment, which forms a general sheath for the muscles in this region; it is attached, behind, to the
olecranon and dorsal border of the
ulna, and gives off from its deep surface numerous
intermuscular septa, which enclose each muscle separately.
