AP I, Chapter 4. The Tissue Level

2. tough form of cartilage, made of thick bundles of collagen fibers embedded in chondroitin sulfate ground substance
4. group of epithelial cells that secrete substances through ducts that open to the skin or to internal body surfaces that lead to the exterior of the body
6. most abundant cell type in connective tissue, secretes protein fibers and matrix into the extracellular space
8. most common type of cartilage, smooth and made of short collagen fibers embedded in a chondroitin sulfate ground substance
12. flexible fibrous proteins that give connective tissue tensile strength
13. muscle cells
14. areolar connective tissue underlying a mucous membrane
15. (also, loose connective tissue) a type of connective tissue proper that shows little specialization with cells dispersed in the matrix
17. release of a substance from a gland via exocytosis
19. type of loose connective tissue that provides a supportive framework to soft organs, such as lymphatic tissue, spleen, and the liver
20. lipid storage cells
21. fibrous protein within connective tissue that contains a high percentage of the protein elastin that allows the fibers to stretch and return to original size

1. fluid or semi-fluid portion of the matrix
3. type of tissue membrane that lines body cavities and lubricates them with serous fluid
5. release of a substance caused by the rupture of a gland cell, which becomes part of the secretion
7. functional cells of a gland or organ, in contrast with the supportive or connective tissue of a gland or organ
9. programmed cell death
10. that part of a cell or tissue which, in general, faces an open space
11. connective tissue membrane that lines the cavities of freely movable joints, producing synovial fluid for lubrication
16. allows cytoplasmic communications to occur between cells
18. embryonic tissue from which connective tissue cells derive
