Where does the intramembranous ossification occur? Describe the process of endochondral ossification, including bone lengthening. Describe the difference between intramembranous and endochondral ossification. Be
A fully-grown adult has 206 bones(骨头),but a baby is born with around 216 bones. Many of the bones are made partly or mostly of cartilage(软骨). As a person grows,the cartilage in his or her body grows,too. Over time,most of it slowly turns into bones. This is called ossificatio...
Ossification may occur at the edge of an area of sheet calcification (J). Reproduced with permission from Otsuka et al. (1). Ca++ = calcium; H/E = hematoxylin-eosin stain; Thr = thrombus. Bone formation (12) comprising trabecula with marrow space is rarely seen in CAD within calcific ...
What does the term "paranasal" mean? Define the following medical term: Percutaneous What does the term gastrointestinal mean? Give examples of when it is used. Define the term endomysium. What is the function of the pinna? Describe the characteristics associated with the cerebrum. ...
Almost a decade later, the existence of two types of cyclooxygenase (COX) was discovered: one constitutive COX-1 that is normally present in most cells and tissues which does not react to glucocorticoids and an inducible COX-2 that is expressed only in the context of inflammation by proinflamma...
Nodular pulmonary ossifications are present in over 80% of patients with honeycombing on HSR CT, where they are more easily detectable than with conventional CT, supporting ILD diagnosis [9]. The enhanced spatial resolution of HSR CT may subjectively and objectively help to elucidate various ...
Does fowl mean bird? Fowl comes from the Old English fugel, "bird," meant simply that — "bird." Today, fowl usually refers specifically tochickens or other kinds of domesticated birdsthat lay eggs or are raised to be eaten. What meat is fowl?
This is because there is no longer a root to support bone ossification/strengthening. With implants, bone growth is stimulated by integrating a dental crown into the jaw bone. This can prevent bone loss in the future. When teeth are lost, bone mass is also lost. To maintain its mass, ...
Top predators of Ice Age North America: Arctodus (short-faced bear– does the short face mean they were happy, unlike a long face? Sorry but they never are shown as very happy, unless it is the joy of whupass) and Homotherium (the other sabre-toothed cat; not the longer-toothed Smi...
Developmentally, biomechanically, evolutionarily, genetically, whatever– why does this PTE happen? There are hints– e.g. this paper proposes why growth rates of long bones favour the formation of “secondary centres of ossification” like this. But I’m unable to satisfy myself with any ...
