The proportions of Type I and II fibers were determined in 37 muscles of Didelphis virginiana, representing 9 body regions. There was a distinct cranial/caudal gradation in the distribution of Type II fibers throughout the trunk musculature. Muscles of the fore- and hind-limbs showed a gradation of Type II fiber across the width of the muscle, being more prominent at the surface. The type II fibers in the tip of the tail showed peculiar staining properties in which the core of each fiber stained much more lightly than did the periphery.

D009893 Opossums New World marsupials of the family Didelphidae. Opossums are omnivorous, largely nocturnal and arboreal MAMMALS, grow to about three feet in length, including the scaly prehensile tail, and have an abdominal pouch in which the young are carried at birth. Didelphidae,Opossum
D000251 Adenosine Triphosphatases A group of enzymes which catalyze the hydrolysis of ATP. The hydrolysis reaction is usually coupled with another function such as transporting Ca(2+) across a membrane. These enzymes may be dependent on Ca(2+), Mg(2+), anions, H+, or DNA.

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
