13. Connective Tissue Three types Fibrous Supportive Fluid
General Functions:
Binds organs
Support
Protection
Immune protection
Movement
Storage
Heat
Others…..

14. Cells + fibers + ground substance = connective tissue
Cells = fibroblasts
Fibers = elastin & collagen
Reticular fibers
Cells = fibroblasts
Fibers = collagen & elastin
Change composition = change function

15. loose dense regular mesentery Tendons & ligaments irregular
Areolar tissue
skin

16. Fibrous connective tissue type and function

17. Supportive connective tissue = cartilage & bone
Cells: chondrocytes
Fibers: collagen & elastin
GS: GAG’s
Perichondrium: dense, irregular CT with chondroblasts

18. hyaline
elastic
fibrocartilage
chondrocytes
collagen & elastin fibers
GAG’s

19. Bone Cells: osteocytes Fibers: collagen Matrix: GAG’s & minerals
Central canal = blood vessel
Surrounded by periosteum

20. Nervous tissue
neurons & glia
electrical & chemical signals
Muscle tissue
muscle fibers
contract when stimulated
skeletal, smooth & cardiac

21. Glands = cell or organ that secretes something
Exocrine glands
secrete stuff to surface
body surface or organ
sweat, tear, mammary, goblet cell
Endocrine glands
secrete stuff into blood
stuff = hormones

22. Membranes line & cover viscera
cutaneous
mucous
