WebJun 14, 2004 · The PMs are elongated, tapered muscles that originate from the inner wall of the ventricles and give rise to the chordae tendineae (connective tissue strands that attach to the edges of the AV valves) at their tips.
WebThe ventricular walls also have papillary muscles that support the atrioventricular valves through the chordae tendineae. The number of these muscles can vary both within and between species (3). Both ventricles may also contain cross-chamber fibrous or muscular bands that typically carry Purkinje fibers.
