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.
The endosteum is a single cellular layer found lining the medullary cavity, the trabeculae, and the central canals. The endosteum consists mostly of osteoblasts and osteoclasts. BONE TISSUE AND STRUCTURE Two types of bone tissue are found in bones:1.rabeculae form an inner framework that is strong, light, and contains red bone marrow. â¢ Yellow bone marrow â Yellow bone marrow is found within the medullary (marrow) cavity of long bones. It consists mostly of adipocytes and functions as a nutrient (fat) storage site.
