M. latissimus dorsi ( fig. 10 )

ORIGIN: From the neural spines of the posterior thoracic vertebrae and from a fascial sheet over the entire lumbar region.

INSERTION: Via a tough aponeurosis on the surface of M. teres major .

REMARKS: This muscle has the same general form in the 11 study taxa. In Desmana and Galemys , the origin of this muscle extends onto the iliac crest. In Uropsilus , this muscle inserts directly on the teres tubercle of the humerus, but in the other genera it inserts on the surface of M. teres major . As

noted by Campbell (1939), in Talpa some anteromedial fibers insert on M. teres major slightly posterior to the rest of the muscle.
