title: [Morphologic evolution of the human extensor digitorum and the abductor pollicis longus muscles. II. Morphologic evolution of the human extensor digiti minimi, the abductor pollicis longus, the extensor pollicis brevis and the extensor pollicis longus muscles].
abstract: The author has studied the macroscopic morphology of the above mentioned muscles over 3 groups of material: 1. 200 superior limbs of adults and 100 superior limbs of human foetuses from 4,8 cm to 37 cm C.H.L. 2. 100 thoracic limbs from 25 species of non-hominid Primates, 13 thoracic limbs from 6 species of Marsupials and 9 thoracic limbs from 2 species of Insectivores. 3. The organogenesis of the muscles in question is studied over the complete series of transversal cuts of 18 superior limbs of human embryos and foetuses from 13,5 mm to 60 mm C.H.L. Comparison and discussion of the facts is made according to the principles of the evolutionary myology.
