Wolverines are observed finding large bones invisible in deep snow and are specialists at scavenging bones specifically to cache. Wolverine upper molars are rotated 90 degrees inward, which is the identifying dentition characteristic of the family Mustelidae (weasel family), of which the wolverine has the most mass, so they can crack the bones and eat the frozen marrow of large animals.
In bone, osteoclasts are found in pits in the bone surface which are called resorption bays, or Howship's lacunae. Osteoclasts are characterized by a cytoplasm with a homogeneous, "foamy" appearance. This appearance is due to a high concentration of vesicles and vacuoles. These vacuoles include lysosomes filled with acid phosphatase.
Bone remodeling is a process which maintains bone strength and ion homeostasis by replacing discrete parts of old bone with newly synthesized packets of proteinaceous matrix. [5] Bone is resorbed by osteoclasts, and is deposited by osteoblasts in a process called ossification. [6] Osteocyte activity plays a key role in this process. Conditions ...
And no matter what you call it — it means the bone is in trouble. "So, there are lots of different types of breaks, but ultimately cracked, broken, fractured, snapped. You pick the term.
The canal of the nutrient foramen is directed away from more active end of bone when one end grows more than the other. When bone grows at same rate at both ends, the nutrient artery is perpendicular to the bone. Most other bones (e.g. vertebrae) also have primary ossification centers, and bone is laid down in a similar manner. Secondary centers
A sesamoid bone is a small, round bone that, as the name suggests, is shaped like a sesame seed. These bones form in tendons (the sheaths of tissue that connect bones to muscles) where a great deal of pressure is generated in a joint. The sesamoid bones protect tendons by helping them overcome compressive forces.
Experiment with whole grain flours: Use whole grain flours such as whole wheat, oat or almond flour in baking recipes to increase the fiber content of homemade bread, muffins and cookies. View ...
Osteoclasts break down bone tissue, and along with osteoblasts and osteocytes form the structural components of bone. In the hollow within bones are many other cell types of the bone marrow . Components that are essential for osteoblast bone formation include mesenchymal stem cells (osteoblast precursor) and blood vessels that supply oxygen and ...
