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.
While Giant Pandas are classified as carnivores, their main source of food is bamboo, up to 99%. Many people assume that bamboo shoots are the only types of food that these bears eat. They also consume stems, leaves and in rare occasions small mammals. Panda bears can spend up to 10 to 12 hours a day feeding.
