<Tr> <Th> Parent (s) </Th> <Td> Patty and Mike Hensel </Td> </Tr> <Tr> <Th> Relatives </Th> <Td> Dakota (brother) Morgan (sister) </Td> </Tr> <P> Abigail Loraine "Abby" Hensel and Brittany Lee Hensel (born March 7, 1990) are American dicephalic parapagus twins; in other words, they are conjoined twins, each of whom has a separate head, but whose bodies are joined . They are highly symmetric for conjoined twins, giving the appearance of having a single body without marked variation from normal proportions . In fact, several vital organs are doubled; each twin has a separate heart, stomach, spine, pair of lungs, and spinal cord . </P> <P> Each twin controls her half of their body, operating one arm and one leg . As infants, the initial learning of physical processes that required bodily coordination, such as clapping, crawling, and walking, required the cooperation of both twins . While they can eat and write separately and simultaneously, activities such as running and swimming require them to coordinate and alternate their actions symmetrically . Other activities as diverse as brushing hair and driving a car require each twin to perform separate actions that coordinate with the other's . </P>
