Document Summary
The skeleton includes various types of connective tissues, primarily cartilage and bone. *although cartilage can be calcified, calcified cartilage is not bone. Bone: function, support, protection, movement, mineral storage, hematopoiesis. Microscopic structure spongy bone: trabeculae: needle-like (flat) pieces, trabeculae appear less organized than structures of compact bone. Chemical composition of bone: organic, cells, osteoid: organic part of matrix; made by osteoblasts, inorganic, hydroxyapatites (mineral salts, proteoglycans, glycoproteins, collagen fibers, osteocytes, osteoblasts, osteoclasts, calcium crystals in and around extracellular matrix, make bones hard. Skeleton is comprised of axial and appendicular structures: skeleton, components, bones, 206, cartilage, joints, ligaments, organization, axial, appendicular, limbs, girdles that attach to axial, skull, vertebral column, rib cage, shoulder and hip bones. G. sphenoid bone: attachment for temporalis muscle, holds teeth, mandibular notch, mandibular condyle (rounded articular projection, mandibular angle, coronoid process, alveolar margin. Protraction and retraction non-angular anterior and posterior movement in transverse plane: elevation and depression lift body part superiorly xi.
