After all, a nail is sharp, and the inside of the nose is sensitive. Putting a foreign object deep into your nasal cavity isn't particularly comfortable, and it can be certainly painful when the performer is learning to do the trick.

Osteoclasts are the bone cell that destroys bone. This allows bone  remodeling, and allows the skeletal system to act as a reservoir  for minerals to maintain blood mineral â¦ levels. Bone cells that are involved in reabsorption and breakdown of the  bone matrix are referred to as osteoclasts.
Lymphocytes. Two main types of lymphocytes are B-cells and T-cells. B-cells are characterized by the presence of immunoglobulins on their surface, and upon stimulation with antigen, they are transformed into plasma cells. Plasma cells are then able to secrete antibodies specific to the antigen.issue neutrophils are activated by chemoattractants at the site of injury. Neutrophils ingest bacteria by phagocytosis and then release enzymes (such as lysozyme) to destroy the bacteria. Eosinophils. Eosinophils migrate from the marrow through the blood into the extravascular tissue, and they survive there for weeks.
