A&P I, Chapter 4.The Tissue Level
Across
- 3. junction: allows cytoplasmic communications to occur between cells
- 4. functional cells of a gland or organ, in contrast with the supportive or connective tissue of a gland or organ
- 7. most abundant cell type in connective tissue, secretes protein fibers and matrix into the extracellular space
- 8. gland: 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
- 10. propria: areolar connective tissue underlying a mucous membrane
- 11. fiber: 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
- 15. membrane: connective tissue membrane that lines the cavities of freely movable joints, producing synovial fluid for lubrication
- 18. fiber: fine fibrous protein, made of collagen subunits, which cross-link to form supporting “nets” within connective tissue
- 19. muscle cells
- 20. lipid storage cells
- 22. secretion: release of a substance caused by the rupture of a gland cell, which becomes part of the secretion
Down
- 1. fiber: flexible fibrous proteins that give connective tissue tensile strength
- 2. tissue: (also, loose connective tissue) a type of connective tissue proper that shows little specialization with cells dispersed in the matrix
- 5. secretion: release of a substance from a gland via exocytosis
- 6. membrane: in epithelial tissue, a thin layer of fibrous material that anchors the epithelial tissue to the underlying connective tissue; made up of the basal lamina and reticular lamina
- 9. that part of a cell or tissue which, in general, faces an open space
- 12. programmed cell death
- 13. tough form of cartilage, made of thick bundles of collagen fibers embedded in chondroitin sulfate ground substance
- 14. embryonic tissue from which connective tissue cells derive
- 16. substance: fluid or semi-fluid portion of the matrix
- 17. cartilage: most common type of cartilage, smooth and made of short collagen fibers embedded in a chondroitin sulfate ground substance
- 21. membrane: type of tissue membrane that lines body cavities and lubricates them with serous fluid
