Der Musculus pyramidalis (Pyramidenmuskel) wird ebenso wie der M. rectus abdominis (gerader Bauchmuskel) zu den vorderen Bauchmuskeln gezählt.
Die Mm. pyramidalis beider Seiten bilden gemeinsam die Fläche einer Pyramide. Allerdings fehlt dieser Muskel bei 10-25% der Menschen.

Die Fasern des M. pyramidalis entspringen am Ramus superior des Os pubis (Schambein) beidseits der Symphyse. Von dort aus verlaufen die Fasern zur Linea alba, welche den M. rectus abdominis in vertikaler Richtung mittig untergliedert.
Die Blutversorgung erfolgt durch die Vasa epigastrica superficialis. Innerviert wird der Muskel durch den N. subcostalis (Th 12) sowie den N. iliohypogastricus aus dem Plexus lumbalis.
Funktion
Die Funktion des M. pyramidalis besteht in der Spannung der Linea alba bzw. in der Spannung der Muskelscheide des Musculus rectus abdominis.
