<P> Each haversian canal is surrounding by varying number ( 5 - 20 ) of concentrically arranged lamellae of bone matrix . Near the surface of the compact bone , the lamellae are arranged parallel to the surface ; these are called circumferential lamellae . Some of the osteoblasts develop into osteocytes , each living within its own small space , or lacuna . Osteocytes make contact with the cytoplasmic processes of their counterparts via a network of small transverse canals , or canaliculi . This network facilitates the exchange of nutrients and metabolic waste . Collagen fibers in a particular lamella run parallel to each other , but the orientation of collagen fibers within other lamellae is oblique . The collagen fiber density is lowest at the seams between lamellae , accounting for the distinctive microscopic appearance of a transverse section of osteons . The space between osteons is occupied by interstitial lamellae , which are the remnants of osteons that were partially resorbed during the process of bone remodeling . </P>
