Paresthesia (Greek para- = abnormal, esthesia = feeling) is abnormal sensation on the skin that has no apparent physical cause (1). Paresthesia includes numbness and tingling, and can be temporary or permanent. Numbness is a decreased or lost sensation in the skin. Tingling is an unusual sensation in the skin. It is often described as feeling of pins and needles, tickling, pricking, creeping, skin crawling, ant crawling, and so on.
The orangutan (Pongo) is a great ape that has fur with a color between red and brown. There are two species of orangutan. They are from Southeast Asia. There are very few of them left, because loss of the jungle has reduced their habitat. There are orangutans on view at the Singapore Zoo.
They live only in Southeast Asia on the islands of Borneo and Sumatra, mostly in Indonesia, but also in the Malaysian states of Sabah and Sarawak on Borneo. Orangutans are currently divided into two distinct species: the Bornean orangutan (Pongo pygmaeus) and the Sumatran orangutan (Pongo abelii).
