Sample sizes for bears: European brown bear: 5 Asiatic black bear: 2 Sun bear: 1
A few important examples of the odd naming conventions: Anconeus = triceps. Endopectoralis = Pectoralis profundus Ectopectoralis = other pectoral muscles (eg, Pectoralis superficialis)
The book made numerous observations of the locomotor peculiarities of bears (based on anatomy info and analysis of a running brown bear with 120 frame/sec film). May add more tomorrow; it is well past 4:00am now and about time I go to bed.
