Posterior Cerebral Artery. Long shunned by Neuroangio for no fault of its own, the PCA is now getting the attention it richly deserves. The PCA is an old vessel, in fact emerging in the lower species prior to development of the MCA.
River Otters are mammals that are relatives of the stoats, weasels, mink, badgers and wolverines. These groups of mammals are known as Mustelids. The Mustelids all have one thing in common, they all have scent glands that they use to mark off their territory. In the wild they live less than 10 years; in captivity they live 10 - 15 years. Range/Habitat: River otters are found along rivers, streams, and lakes and also in estuaries, coastal bogs, and large marine waterways such as Puget Sound and the Strait of Juan de Fuca.
