Atrophy of paraspinal muscles is common in low back pain (LBP). Early studies report atrophy and abnormalities of the paraspinal muscles in 20% to 60% of people with chronic LBP.More recent data suggest a reduced cross-sectional area of multifidus at L4 and/or L5 in chronic LBP.ntroduction.

Hyenas usually bear litters of two to four cubs, which, unlike the other two species, are born with their eyes open. Cubs begin to eat meat from kills near the den at about 5 months, but they are suckled for as long as 12 to 18 months, an unusually long time for carnivores.
In fact, the Giant Panda eats nothing but bamboo! Other bears, however, take meat when they can find it and fill in the rest of their diet with vegetation. Because most bears are apex predators, or the top of the food chain in their habitat, they rarely have to hunt and can simply steal meat from other animals.
