Stromal stem cells: This type of stem cell provides nutrients in both the secondary lymphoid organs and non-lymphoid tissues. Yellow marrow is mostly fat and as we age, it can be found in places where red marrow once resided — some of the bones in our arms, legs, fingers and toes, ...
The much greater preservation of bones and teeth is made possible by the fact that they are comprised of mostly mineral matter. Teeth, for exam- ple, have a very tough outer covering--called enamel--that is highly mineralized. Consequently, teeth are especially resistant to natural processes ...

A simpler explanationmight be that Chinese ancestors are not feared because they are not conceived...
Long bones: Long bones have a slightly curved shaft capped on both sides with hyaline cartilage and are longer than they are thick. They're made mostly of compact bone, allowing them to support great amounts of weight and withstand pressure. The femur is an excellent example of the strength...
All bones function to provide support to our bodies. Some bones function to provide support but are mostly there to provide protection to a sensitive... Learn more about this topic: The Skeletal System: Function and Terms from Chapter 5/ Lesson 1 ...
The various approaches proposed for segmentation of bony structures in CT scans [6] are mostly semi-automated and focusing on parts of the skeleton. To be of clinical use, segmentation of bone in CT scans needs to be fast, reliable and comprising relevant major parts of the skeleton. Machine...

Although the Neandertal sample includes cranial and postcranial elements (Fig. 1), with long bones best represented and extremities mostly absent, the minimum number of elements (MNE = 35) demonstrates a very low overall skeletal representation. The best represented elements are, in ...
Information relating to locomotion in Ardipithecus ramidus (4.4 mya, Aramis and Gona, Ethiopia) is derived mostly from an incomplete foot and a few isolated metatarsal bones (Lovejoy et al., 2009; White et al., 2009). The talus was found to be ape-like, and its shape implies that A. ...
