Document Summary

Blood cell production in red marrow. Covered by glove like membrane (periosteum) that nourishes bone. Made of osteons with central canal containing blood vessels. Contains living bone cells (osteocytes) chambers called lacunae. Lattice of tiny beams and thin plates of bone with open areas in btwn. Made of plates with paces filled with red bone marrow/yellow. Epiphysis: ends of bone made of spongy bone. Diaphysis: shaft of bone made of compact bone and filled with yellow marrow. Articular cartilage: hyaline cartilage found on ends of long bones. Red bone marrow: makes blood cells found in spongy/flat bones. Periosteum: living, outer covering of fibrous connective tissue. Ligaments: fibrous connective tissues that connect long bones. Cartilage flexible, connective tissue categorized based on arrangement of matrix fibers. Hyaline: end of long bones, nose, ends of ribs, larynx, trachea. Fibrocartilage: disks between vertebrae and in the knee, stronger than hyaline cartilage. Elastic: ear flaps and epiglottis, more flex than hyaline.
