<p>Spongy Bone = Contains trabeculae that enclose bone marrow and vessels Compact Bone = Consists of osteons as functional units with Haversian canals Periosteum = Outermost layer anchored by Sharpey's fibers for fracture repair Endosteum = Site of production for osteoprogenitor cells and osteoclasts</p> Signup and view all the answers

<p>Osteoclasts = Remove bone during growth and remodeling in Howship's lacunae Osteoblasts = Facilitate mineralization of osteoid matrix with dendritic extensions Osteocytes = Differentiated osteoblasts trapped in bone matrix with cytoplasmic projections Osteoprogenitor cells = Involved in production of new bone cells</p> Signup and view all the answers

<p>Woven Bone = Lower calcium salt content per unit area compared to lamina dura Lamina Dura = More radio-opaque appearance in x-ray imaging Trabeculae = Visible as spongy network in radiographs Haversian Canals = Seen as central channels in compact bone on x-rays</p> Signup and view all the answers

<p>Canaliculi = Provide communication between adjacent cavities in bone Sharpey's Fibers = Anchors periosteum along the outer surface of bones Howship's Lacunae = Location where osteoclasts remove bone during growth and remodeling Dendritic Extensions = Interconnect osteoblasts facilitating mineralization of osteoid matrix</p> Signup and view all the answers

<p>Woven Bone = Lower calcium salt content per unit area compared to lamina dura, less radio-opaque Lamina Dura = More radio-opaque appearance on x-ray imaging, seen as dense lines around teeth roots Trabeculae = (Spongy Bone) - Visible as mesh-like network on radiographs, supporting cancellous bone structure Haversian Canals = (Compact Bone) - Central channels seen on x-rays, containing blood vessels and nerves</p> Signup and view all the answers

<p>Osteoclasts = Located in Howship's lacunae and remove bone during growth and remodeling. Osteoblasts = Interconnected via dendritic extensions to facilitate mineralization of osteoid matrix. Osteocytes = Differentiated osteoblasts trapped within the bone matrix containing cytoplasmic projections.
