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.
Striped hyenas live in Africa, Arabia, Asia Minor and India in savanna, thorn bush, and stony desert regions. They weigh from 55 to 121 pounds. Striped and brown hyenas are predominantly scavengers, though they do supplement their diets with small prey from insects to foxes.The aardwolf, also, lives in Africa.hey live in territorial clans of related individuals, sometimes up to 80 members. Spotted hyenas are hunters and scavengers. Besides flesh, they eat skin, bones, and even animal droppings. Spotted hyenas are 28 to 35 inches tall and weigh 90 to 190 pounds.
