- 13. looks like many layers but isn't; secretion and movement of mucus by ciliary action
- 16. shiny white ground substance with fine collagen fibers; ends of long bones, anterior ends of ribs, nose; provides smooth surfaces for movement at joints
- 18. detects changes inside and outside the body and initiates and transmits nerve impulses that coordinate body activities to help maintain homeostasis
- 19. lines a body cavity open to the exterior; secretes mucus, which prevents cavities from drying out
