Across
- 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
Down
- 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
