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.
Taxonomy, morphology, growth, evolution: There are two species of orangutans, Pongo pygmaeus in Borneo, and Pongo abelii in Sumatra. They are the largest arboreal animals in the world and their bodies are adapted to eat, sleep, and move in the forest canopy.
