Across
- 1. / The fluid circulating through the heart, arteries, veins, and capillaries of the circulatory system.
- 7. / a cell that has secreted the matrix of cartilage and become embedded in it.
- 8. Matrix / is a collection of extracellular molecules secreted by cells that provides structural and biochemical support to the surrounding cells.
- 11. / is an anatomical term for loose connective tissue composed of adipocytes. Its main role is to store energy in the form of fat, although it also cushions and insulates the body.
- 12. / is a large white blood cell that is an integral part of our immune system. Its job is to locate microscopic foreign bodies and 'eat' them.
- 13. Cells / is a type of white blood cell. Specifically, it is a type of granulocyte derived from the myeloid stem cell that is a part of the immune and neuroimmune systems and contains many granules rich in histamine and heparin.
- 14. / an individual fiber that varies in diameter from less than 1 mcm to about 12 mcm and is composed of fibrils; the fibers, which are usually arranged in bundles, undergo some branching and are of indefinite length; chemically the fiber is a glycoprotein, collagen, which yields gelatin upon boiling; it constitutes the principal element of irregular connective tissue, tendons, aponeuroses, and most ligaments, and occurs in the matrix of cartilage, dentin, cementum, and osseous tissue.
- 16. Cartilage / yellow cartilage is a type of cartilage present in the outer ear, Eustachian tube and epiglottis. It contains elastic fiber networks and collagen fibers. The principal protein is elastin.
- 17. / a flexible but inelastic cord of strong fibrous collagen tissue attaching a muscle to a bone.
- 18. / is a type of fiber in connective tissue composed of type III collagen secreted by reticular cells. Reticular fibers crosslink to form a fine meshwork (reticulin).
Down
- 2. / a cell that lies within the substance of fully formed bone. It occupies a small chamber called a lacuna, which is contained in the calcified matrix of bone.
- 3. / cartilage that contains fibrous bundles of collagen, such as that of the intervertebral disks in the spinal cord.
- 4. / Loose connective tissue is the most common type of connective tissue in vertebrates. It holds organs in place and attaches epithelial tissue to other underlying tissues.
- 5. / The dense, semirigid, porous, calcified connective tissue forming the major portion of the skeleton of most vertebrates. It consists of a dense organic matrix and an inorganic, mineral component.
- 6. / is a type of cell that synthesizes the extracellular matrix and collagen, the structural framework (stroma) for animal tissues, and plays a critical role in wound healing.
- 9. Cartilage / a translucent bluish-white type of cartilage present in the joints, the respiratory tract, and the immature skeleton.
- 10. / is a type of connective tissue with fibers as its main matrix element. The fibers are mainly composed of type I collagen. Crowded between the collagen fibers are rows of fibroblasts, fiber-forming cells, that generate the fibers.
- 15. / a short band of tough, flexible, fibrous connective tissue that connects two bones or cartilages or holds together a joint.
