Plesiorycteropus not inclined relative to each other, but about parallel. The astragalus, which is known from four examples, is wide and short and contains a uniquely large posteromedial process. Seven metapodials (middle hand or foot bones) are known, rather variable in size, but MacPhee was unable to separate metacarpals (from the hand) and metatarsals (from the foot). All are rather short and are broad proximally and narrow distally. Among the few known phalanges, the proximal phalange is shorter than the middle one and the distal phalanges are narrow and clawlike. The forelimbs of "Plesiorycteropus" show specializations for "scratch-digging", in which the
Effect of spaceflight on the human body adult. In space, however, there is an increase in osteoclast activity due to microgravity. This is a problem, because osteoclasts break down the bones into minerals that are reabsorbed by the body. Osteoblasts are not consecutively active with the osteoclasts, causing the bone to be constantly diminished with no recovery. This increase in osteoclasts activity has been seen particularly in the pelvic region, because this is the region which carries the biggest load with gravity present. A study demonstrated that in healthy mice, osteoclasts appearance increased by 197%, accompanied by a down-regulation of osteoblasts and growth factors that are known
