Across
- 2. mammals that have four legs
- 6. gelatin-like protein that is part of the composition of bones
- 8. type of joint that allows free movement
- 9. type of muscle that is only found in the muscular wall of the heart
- 13. bone material that is spongy and generally found in the ends of long bones
- 15. type of muscle that surrounds the hollow internal organs of the body, such as the blood vessels, stomach, intestines, and bladder
- 16. a skeletal system found inside the body
- 18. the portion of the skeletal system that is composed mainly of the skull, vertebral column and rib cage
- 19. bones that have more length than width and are generally cylindrical in shape
- 21. bone material that is composed of Haversian systems that usually found on the outside of bones and surrounding the bone marrow
Down
- 1. type of joint that generally do not permit any type of movement and are typically found in the skull
- 3. type of joint that consist of discs that allow very limited movement and are mainly found in the vertebrate
- 4. type of muscle that has dark bands that cross each muscle fiber; muscle that composes the “meat” from farm animals
- 5. connective tissue that is composed of calcium compounds and gelatin-like protein called ossein
- 7. a skeletal system found outside the body
- 10. a microscopic mass of protoplasm that is the structural and functional unit of a plant or animal organism
- 11. contractile tissues that allow the animal to move
- 12. connective tissue that is flexible and elastic; it also forms the early skeletal structure of the vertebrate embryo
- 14. bones that come in a variety of shapes and sizes but their length and width are nearly the same
- 17. a bone cell, particularly one encased in hard bone
- 20. bones that are found mostly in the head; usually thinner that other bones
