unit 5:bones

4. fundamental functional unit of much compact bone
6. any of the small channels in the bone that transmit blood vessels from the periosteum into the bone and that communicate with the haversian canals
7. a cell that secretes the matrix for bone formation
10. highly specialized connective tissue of diarthrodial joints
11. a dense layer of vascular connective tissue enveloping the bones except at the surfaces of the joints
12. a thin layer, membrane, scale, or platelike tissue or part, especially in bone tissue
14. hyaline cartilage plate in the metaphysis at each end of a long bone
16. a cavity or depression, especially in bone
17. the shaft or central part of a long bone
18. cerebrospinal fluid-filled space that runs longitudinally through the length of the entire spinal cord
19. bony matrix is solidly filled with organic ground substance and inorganic salts, leaving only tiny spaces (lacunae) that contain the osteocytes, or bone cells

1. one marrow characterized by meshes of the reticular network that contain the developmental stages of red blood cells, white blood cells, and megakaryocytes
2. a large multinucleate bone cell that absorbs bone tissue during growth and healing
3. made up of spongy bone, which is bone with tiny holes similar to lattices
5. Enlarged terminal part of the bone, nearest the center of the body, made of spongy tissue and articulating with neighboring bones
8. junction of the epiphysis and diaphysis of a long bone where growth in length occurs
9. the central cavity of bone shafts where red bone marrow and/or yellow bone marrow (adipose tissue) is stored
13. bone marrow that is yellow with fat; found at the ends of long bones in adults
15. spicules form a latticework, with interstices filled with embryonic connective tissue or bone marrow
20. cell that lies within the substance of fully formed bone
