Blood flow to long bones indicates activity metabolism in mammals, reptiles and dinosaurs.
The cross-sectional area of a nutrient foramen of a long bone is related to blood flow requirements of the internal bone cells that are essential for dynamic bone remodelling. Foramen area increases with body size in parallel among living mammals and non-varanid reptiles, but is significantly larger in mammals. An index of blood flow rate through the foramina is about 10 times higher in mammals...
متن کاملOsteonic organization of limb bones in mammals, including humans, and birds: a preliminary study.
As it is well known, bone tissue is characterized by a calcified extracellular matrix which makes this tissue suitable to support the body and protect the inner organs. Lamellar bone tissue is organized in lamellae, 3-7 microm in thickness, and arranged concentrically around vascular channels: the basic structure in this type of organization is called Haversian system or osteon and the diameter...

Counting the Fingers of Birds and Dinosaurs
Homologies of the three fingers in birds have been debated for more than a century. Paleontologists have traditionally identified avian digits as I-II-III largely on the basis of phalangeal counts, whereas embryologists number them II-III-IV on the basis of development in the egg. The report by Ann C. Burke and Alan Feduccia (1) is a synthesis of the embryological evidence. They observe that in...
متن کاملStructure of long bones in mammals.
Techniques for staining (silver, osmium, metal sulfides, ink) and microphotography (epi-illumination) of polished bone surfaces have been developed to visualize the three-dimensional structure of the shafts of mammalian long bones. Bone is a two-compartment system with capillaries and some kinds of connective tissue in one compartment separated from fibers of bone collagen, often forming lamell...
