The furcula (Latin for "little fork"; pl.: furculae) [a] or wishbone is a forked bone found in most birds and some species of non-avian dinosaurs, and is formed by the fusion of the two clavicles. [1] In birds, its primary function is in the strengthening of the thoracic skeleton to withstand the rigors of flight.
Bird anatomy, or the physiological structure of birds' bodies, shows many unique adaptations, mostly aiding flight.Birds have a light skeletal system and light but powerful musculature which, along with circulatory and respiratory systems capable of very high metabolic rates and oxygen supply, permit the bird to fly.
The anatomy of bird legs and feet is diverse, encompassing many accommodations to perform a wide variety of functions. [ 1 ] Most birds are classified as digitigrade animals, meaning they walk on their toes rather than the entire foot.
This stylised bird skeleton highlights the synsacrum Pelvis of a Gull; formed by the Synsacrum (fused vertebrae placed centrally) and the two innominate bones either side. The synsacrum is a skeletal structure of birds and other dinosaurs, in which the sacrum is extended by incorporation of additional fused or partially fused caudal or lumbar ...
The skeleton of a bird wing. Places of attachment of various groups of flight feathers are indicated. The mute swan with outstretched wings Wing of the white-tailed eagle. Bird wings are a paired forelimb in birds. The wings give the birds the ability to fly, creating lift. Terrestrial flightless birds have reduced wings or none at all (for ...
This stylised bird skeleton highlights the uncinate processes The uncinate processes of the ribs are extensions of bone that project caudally from the vertical segment of each rib . (Uncinate means hooked from Latin uncinatus , from uncinus , barb, from uncus , hook.)
Pigeon skeleton. Number 8 indicates both left and right tarsometatarsus. The tarsometatarsus is a bone that is only found in the lower leg of birds and some non-avian dinosaurs. . It is formed from the fusion of several bones found in other types of animals, and homologous to the mammalian tarsus (ankle bones) and metatarsal bones (foo
Pigeon skeleton; numbers 10 and 11 indicates the tibiotarsus. The tibiotarsus is the large bone between the femur and the tarsometatarsus in the leg of a bird. It is the fusion of the proximal part of the tarsus with the tibia. A similar structure also occurred in the Mesozoic Heterodontosauridae.
