Light output, measured in lumens. Most tactical flashlights put out 60+ lumens, while some go up to 1,600+. Comparatively, most regular flashlights put out just 15-20 lumens. Run time, which references how long it takes for the battery to reach 10% of its initial output. Ex: How long it would take a 100 lumen flashlight to reach a 10-lumen output.
Histology of compact bone showing osteon. Each osteon consists of concentric layers, or lamellae, of compact bone tissue that surround a central canal, the haversian canal. The haversian canal contains the bone's blood supplies. The boundary of an osteon is the cement line. Between adjoining osteons, there are angular intervals that are occupied by interstitial lamellae. These lamellae are remnants of osteons that have been mostly destroyed.
Osteocytes will be found enclosed in bone. Osteoclasts are bone-resorbing cells (-clast means to break; osteoclasts break down bone). They are large, multinucleate cells that form through the fusion of precursor cells.steoblasts are bone-forming cells. They are connective tissue cells found at the surface of bone. They can be stimulated to proliferate and differentiate as osteocytes. Osteocytes are bone cells. Osteocytes manufacture type I collagen and other substances that make up the bone extracellular matrix.
