Tibia, inner and larger of the two bones of the lower leg in vertebrates—the other is the fibula. In humans the tibia forms the lower half of the knee joint above and the inner protuberance of the ankle below. Learn more about the tibia in this article.
bone (talus, or astragalus), with thefibulaandtibiaof the lower leg forms the actual ankle joint, although the general region is often called the ankle. The chief motions of the ankle are flexion and extension. Like other synovial joints (those joints in which fluid is present), the ankle...
The neonate is blind, earless and hairless. Only three functions of its body are operational, its sense of smell, its strong front legs and claws, and its instinct to find the pouch. The neonate thrusts forward with no assistance from its mother, dragging its tiny body - onlyabout the si...
They are insiders, and information about gaining access to the catacombs is kept within the tightly knit group. The cataphiles have been creating and building their own community within the old quarries and tunnels for years. Some paint art, furnish rooms, or party with fellow tunnel-dwellers, ...
These include long limbs, a long tibia (the shin bone) and metatarsus (the long bones of the foot), as well as short toes. The first fossils of Gallimimus were discovered in the early 1970s, and the creature was named in 1972 by Rinchen Barsbold, Halszka Osmólska and Ewa Roniewicz...
Though cancellous bone only makes up about 20 percent of the body's bone mass, it plays important roles in body function. It provides structural stability and acts as a kind of shock absorber inside the bone, but without adding too much to the overall weight of the body. ...
Birds’ knees are not seen– we see a joint that is actually comparable to human ankles. It is commonly thought that birds’ knees bend forwards, but the joint we see and get confused by is the section between tarsus and tibia. Bird’s knees actually bend the same way as ours but we...
armatus includes the dentary and teeth of the sauropod Diplodocus, sauropod limb bones, and an Allosaurus tibia. Many subsequent studies regarded Hypsirhophus as a synonym for Stegosaurus. However, Peter Galton (2010) proposed that it differs based on vertebral characteristics. In August of the ...
(Not only that, reader Don Keck tells me it's probably a femur, not a tibia, so the eBay description wasn't even right in that regard.) Interestingly, there was a 0.074% trace of titanium, which makes me think it was probably cast in the same mold, or maybe the aluminum was ...
Red panda’s fibula and tibia are attached in a way that allows their feet torotate 180 degrees, giving their curved claws a better angle to grip tree bark. Their Fur Provides Camouflage Both species of red panda have a soft, dense woolly undercoat covered by long, coarse guard hairs.Olli...
