- 66. lateral bony projection that originates at the vertebral arch; occur in pairs, one on each side
- 67. a freely movable joint
- 70. bone-forming cells
- 72. an immovable joint
- 76. double-layered connective tissue membrane that covers and nourishes the bone
- 77. three to five fused bones forming the inferior section of the spine; tailbone
- 79. the seven vertebrae of the neck region.

- 84. bony projection from the posterior of the vertebral arch
Down
- 1. the most inferior of the three bones making up the sternum
- 3. multiaxial synovial joint in which the rounded head of one bone fits into a socket (depression) on the other
- 4. uniaxial synovial joint in which the rounded end of one bone fits into a sleeve or ring of bone or ligaments.
- 5. breastbone; flat bone composed of the manubrium, body, and xiphoid process
- 8. the junction of two or more bones; an articulation
- 10. arch formed by connecting all bony projections posteriorly from the centrum
- 14. one of the five bones of the palm of the hand
- 16. central cavity in the diaphysis of a long bone containing marrow
- 17. collar bone; part of the pectoral girdle that attaches medially to the manubrium and laterally to the scapula
- 18. bones joined by fibrous tissue; no joint cavity is present
- 19. portion of the body connecting the head to the thorax that contains the trachea and esophagus
- 20. elongated shaft of a long bone
- 21. the bones of the finger or toe
- 22. bones united by cartilage; no joint cavity is present
- 23. a furrow on the brain, less deep than a fissure.
- 25. elongated bursa that wraps a tendon subject to friction
- 28. air-filled spaces within the maxillae on either side of the nasal cavity that are lined with mucous membrane
- 32. the portion of a vertebra between the transverse process and the spinous process
- 34. bones of the thorax, including ribs, sternum, and thoracic vertebrae; also called thoracic cage
- 35. triangular bone of the pectoral girdle that articulates with the clavicle and humerus
- 36. the skull, vertebral column, ribs, and sternum.
- 40. the structural and functional unit of compact bone;
- 42. a mature bone cell
- 45. extremely small tubular passage or channel
- 46. long bone of the upper arm; articulates with the scapula to form the shoulder joint and the radius and ulna to form the elbow joint
