Demodectic Mange in Dogs. Save to mypetMD. Mange (demodicosis) is an inflammatory disease in dogs caused by various types of the Demodex mite. When the number of mites inhabiting the hair follicles and skin of the dog become exorbitant, it can lead to skin lesions, genetic disorders, problems with the immune system and hair loss (alopecia).
Osteoclasts are found on top of or next to existing bone tissue, sometimes in close proximity to osteoblasts. There is on-going race between the two cell types; osteoblasts make bone tissue while osteoclasts reabsorb it.
During bone formation, the surface layer of osteoblasts consists of cuboidal cells, called active osteoblasts. When the bone-forming unit is not actively synthesizing bone, the surface osteoblasts are flattened and are called inactive osteoblasts. Osteocytes remain alive and are connected by cell processes to a surface layer of osteoblasts. Osteocytes have important functions in skeletal maintenance. Osteoclasts. Osteoclasts break down bone tissue, and along with osteoblasts and osteocytes form the structural components of bone.
