Across
- 2. separate tissues and protect them from mechanical stress.
- 3. (yellow, reddish brown, black)- exposure to sunlight stimulates melanomas
- 5. forms the base of the hair follicle
- 8. the outermost layer of skin on your body
- 11. passive scaffolds that increase the surface area of the gut wall.
- 13. store the cell's DNA, maintain its integrity, and facilitate its transcription and replication.
- 15. helps make your skin flexible and strong
- 16. holds in water and keeps your skin hydrated and healthy
- 18. found in armpit and genital areas, larger than eccrine and ducts empty into hair follicles
- 20. the visible part of the hair that sticks out of the skin
- 22. bind structures together, form a framework and support for organs and the body as a whole, store fat, transport substances, protect against disease, and help repair tissue damage.
- 24. store energy in the form of fat, cushion internal organs, and insulate the body
- 26. protection, secretion and absorption.
- 27. distribute oxygen-rich blood to your body
- 28. the body's raw materials — cells from which all other cells with specialized functions are generated.
- 30. generates heat when the body is cold, muscles contract all at once, causing the hair to "stand up straight" on the skin
Down
- 1. protects the tissues deeper in your body, such as blood vessels, muscle and internal organs
- 4. found in the brain, spinal cord, and nerves. It is responsible for coordinating and controlling many body activities.
- 6. found all over the skin except palms of hands and soles of feet
- 7. pigment in red blood cells
- 9. undergoes almost continuous mitosis to replace cells lost by abrasion.
- 10. ends deep in the dermis at the hair bulb, and includes a layer of mitotically active basal cells called the hair matrix.
- 12. orange-yellow, plentiful in carrots and deep yellow green leafy vegetables. Large consumption of carotene rich food results in skin with yellow-orange cast
- 14. comprises the outermost layer of the non-keratinizing epithelium
- 17. found all over the body, regulates body's heat
- 19. transport the air, blood, fluids, food and other substances inside the body, or between the body and the exterior.
- 21. composed of cells that have the special ability to shorten or contract in order to produce movement of the body parts. The tissue is highly cellular and is well supplied with blood vessels.
- 23. grow hair
- 25. gel-like fluid inside the cell.
- 29. mixtures of oily substances and fragmented cells, product of sebaceous glands. Prevents hair from being brittle, keeps skin soft and moist
