Across 6. in which the bony matrix is solidly filled with organic ground substance and inorganic salts, leaving only tiny spaces (lacunae) that contain the osteocytes, or bone cells. 8. consists of the 80 bones along the central axis of the human body. It is composed of six parts; the human skull, the ossicles of the middle ear, the hyoid bone of the throat, the rib cage, sternum and the vertebral column 9. is the main or mid section (shaft) of a long bone 10. is the central cavity of bone shafts where red bone marrow and/or yellow bone marrow (adipose tissue) is stored 15. are hard, dense bones that provide strength, structure, and mobility. 16. is one of the two essential processes during fetal development of the mammalian skeletal system by which bone tissue is created. 17. is a lighter, weaker type of bone. One of the two types of bone, spongy bone contains red marrow 19. are bones which, from their peculiar form, cannot be grouped as long bone, short bone, flat bone or sesamoid bone. 21. a star-shaped cell, is the most abundant cell found in compact bone 22. are soft spots on a baby's head which, during birth, enable the bony plates of the skull to flex, allowing the child's head to pass through the birth 23. Any of the tiny, interconnecting, longitudinal channels in bone tissue through which blood vessels, nerve fibers, and lymphatics. 24. is a hyaline cartilage plate in the metaphysis at each end of a long bone 25. is the process of laying down new bone material by cells called osteoblasts 26. is the rounded end of a long bone, at its joint with adjacent bone(s). 27. are made up of a layer of spongy bone between two thin layers of compact bone. Their shape is flattened, not rounded. 28. is a membrane that lines the outer surface of all bones, except at the joints of long bones.

Down 1. is the flexible tissue found in the interior of bones 2. is composed of 126 bones in the human body.including the upper and lower limbs. 3. is a small, often microscopic, tissue element in the form of a small beam, strut or rod 4. are mononucleate cells that are responsible for bone formation 5. is a bone embedded within a tendon. 7. The growth in diameter of bones around the diaphysis occurs by deposition of bone beneath the periosteum. 11. is a thin layer of connective tissue that lines the surface of the bony tissue that forms the medullary cavity of long bones 12. are defined as being approximately as wide as they are long and have a primary function of providing support and stability with little movement. 13. is the process where new blood cells are produced 14. is the smooth, white tissue that covers the ends of bones where they come together to form joints. 18. is a type of bone cell that removes bone tissue by removing its mineralized matrix and breaking up the organic bone 20. is the study of bones musculoskeletal system
