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