|---|---|
| 1. Tissue | Group of similar cells that perform a common function. |
| 2. Connective Tissue | Type of tissue that binds structures together, provides support and protection, fills spaces, stores fat, and forms blood cells; adipose tissue, cartilage, bone, and blood are types of |
| 3. Collagen Fibers | White fiber in the matrix of connective tissue; gives flexibility and strength |
| 4. Elastic Fibers | Yellow fiber in the matrix of connective tissue, providing flexibility. |
| 5. Fibroblasts | Cell in connective tissues that produces fibers and other substances. |
| 6. Adipose Tissue | Connective tissue in which fat is stored. |
| 7. Tendons | Strap of fibrous connective tissue that connects skeletal muscle to bone. |
| 8. Ligaments | Tough cord or band of dense fibrous connective tissue that joins bone to bone at a joint. |
| 9. Cartilage | Connective tissue in which the cell cells lie within lacunae separated by a flexible protein Aceous matrix. |
| 10. Fibrocartilage | Cartilage with a matrix of strong collagenous fibers. |
| 11. Compact Bone | Type of bone that contains osteons consisting of concentric layers of matrix and osteocytes in lacunae. |
| 12. Spongy Bone | Porous bone found at the end of long bones where red bone marrow is sometimes located. |
| 13. Blood | Type of connective tissue in which cells are separated by a liquid called plasma. |
| 14. Red Blood Cells | (erythrocytes) - Formed element of the blood that contains hemoglobin and carries oxygen from the lungs to the tissues. |
| 15. White Blood Cells | (leukocytes) - Type of blood cell that is transparent without staining and protects the body from invasion by foreign substances and organisms. |
| 16. Platelets | (thrombocytes) - Fragment of a cell found in the blood that is necessary for blood clotting. |
| 17. Lymph | Fluid derived from intestinal fluid, that is carried in lymphatic vessels. |
| 18. Muscular Tissue | Type of tissue composed of fibers that can shorten and thicken. |
| 19. Skeletal Tissue | (Skeletal Muscle) Striated voluntary muscle tissue found in muscles that move the bones |
| 20. Smooth Muscle | Nonstriated involuntary muscle tissue found in the walls of internal organs, also called visceral muscle |
| 21. Cardiac Muscle | Striated involuntary muscle found only in the heart. |
| 22. Nerves | Bundle of long axons outside the central nervous system. |
| 23. Neuron | Cell of the nervous system that transmits nerve impulses; consist of three parts: dendrites, cell body, and axon. |
| 24. Epithelial Tissue | Type of tissue that lines, hollow organs and covers surfaces; also called epithelium. |
| 25. Squamous Epithelium | Type of epithelial tissue that contains fat cells. |
| 26. Cuboidal Epithelium | Type of epithelial tissue with cube-shaped cells. |
| 27. Columnar Epithelium | Type of epithelial tissue in which the cells have a shape similar to a vertical column or pillar. |
| 28. Gland | Epithelial cell or group of epithelial cells specialized to secrete a substance. |
| 29. Exocrine Glands | Gland that secretes its product to an epithelial surface directly through ducks. |
| 30. Mucous Membranes | Membrane that lines tubes and body cavities that open to the outside of the body also called mucosa. |
| 31. Serous Membranes | Membrane that covers internal organs and lines cavities without an opening to the outside of the body also called serosa. |
| 32. Synovial Membranes | Membrane that forms the inner lining of the capsule of a freely movable joint. |
| 33. Meninges | (sing., meninx) - Protective Membranous coverings about the central nervous system. |
| 34. Subcutaneous Layer | Tissue layer that lies just beneath the skin and contains adipose tissue. |
| 35. Epidermis | Region of skin that lies above the dermis. |
| 36. Dendritic Cells | Specialized epidermal cell that assets the immune system; previously called langerhans cells. |
| 37. Melanocytes | Melanin-producing cell found in skin. |
| 38. Dermis | Region of skin that lies beneath the epidermis. |
| 39. Positive Feedback | Mechanism in which the stimulus mitiates reactions that lead to an increase in the stimulus. |
| 40. Negative Feedback | Mechanism of homeostatic response in which a stimulus initiates reactions that reduce the stimulus. |
