Spongy Bone (A) - green Volkman's Canal (B) - orange Osteocytes (C) - red Haversian Canal (D) -- yellow Compact Bone (E) -- leave white Periosteum (F) - pink. An osteon contains osteocytes, lamellae, and a central canal, and is found in compact bone only. Mature bone cells, called (2) maintain bone in a viable state. Explain skeletal cartilage structure in terms of water content, matrix, vascularity, and outer protective covering ... connects diaphysis and epiphysis-includes sight of bone elongation: epiphyseal plate ... around 2% of bone mass-osteocytes, osteoblasts, osteoprogenitor cells and osteoclasts. BONE MATRIX COLORING. Several descriptions of bone structure are given below. The structure of bone tissue suits the function. 134-138) 6 osteoclasts- giant bone-destroying cells activated by parathyroid hormone (PTH) osteoblasts- produce bone matrix around itself creating an osteocyte osteocyte- a mature bone cell bone remodeling- necessary to maintain proportions & strength in bones as they grow Disuse such as that caused by paralysis or severe lack of exercise results in muscle and bone (3) Large tubercles and/or increased deposit of bony matrix occur at sites of (4) Immature, or matrix-depositing, bone cells are referred to as (5) Osseous Tissue: Bone Matrix and Cells Bone Matrix Osseous tissue is a connective tissue and like all connective tissues contains relatively few cells and large amounts of extracellular matrix. 2. Figure 6.3.3 – Anatomy of a Flat Bone: This cross-section of a flat bone shows the spongy bone (diploë) covered on either side by a layer of compact bone. D. Bone Formation, Growth, and Remodeling ( pp. Which of the following bone tissues is adapted to support weight and withstand tension stress? Spongy bone is well adapted to accept stress in many directions, which makes it good for shock absorption. OSTEOCYTES. Includes the osteocytes, lamella, haversian system, and other features of the bone matrix. ... --osteoblasts secrete bone matrix and become surrounded by it (cells are now osteocytes)--matrix calcifies and hardens --compact bone replaces most spongy bone *Occurs by appositional growth ONLY* Growth of Bones. The cell responsible for secreting the matrix of bone is the _____.
