3. Four mainTypes of Animal Tissues

4. Epithelial Tissue(Covering) • Tightly-joined closely-packed cells (sel-sel yang padat,rapat, ketat) • One side of epithelium exposed to air, other side attached to a basement membrane, a dense mat of connective tissue (salahsatusisijar.epitelberhubungankelingkungan external dansatusisilagimelekatpadamembranbasal,jar.ikat) • Covers outside of the body and lines internal organs and cavities (menutupiseluruhpermukaantubuh) • Provides surface for absorption, excretion and transport of molecules (membantupenyerapan, ekskresidantranspormolekul)

5. Types of Epithelial Tissue • Cell shape • Squamous • Cuboidal • Columnar • Number of cell layers • Simple • Pseudostratified • Stratified • RELATE STRUCTURE TO FUNCTION!

6. Connective tissue(Framework) • Binding and support of other tissues (mengikatdanmenyokongjaringan lain) • Large amount of extracellular matrix (banyakmengandungmatiksextraselular) • Extracellular matrix consists of network of fibers in liquid, jelly-like or solid matrix

8. Muscle Tissue(Movement) • Composed of long cells called muscle fibers • Contraction  movement

9. Nervous Tissue(Control) • Transmits nerve impulses from one part of an animal to another (menyampaikanimpulssarafdarisatubagianmenujubagian lain) • Consists of a cell body and long extensions called dendrites (towards cell body) and axons (towards another cell or an effector) (terdiriatasbadansel, dendrit, axon) Axon Dendrite Cell body

12. Epithelial Tissues • Epithelia comes in 2 forms: • Glandular epithelia • Membranous epithelia • Functions: • Protection • Absorption • Filtration • Excretion • Secretion • Sensory reception

13. Types of Epithelium a. Shape of the cell • Cuboidal (like dice) • Columnar (like bricks on end) • Squamous (flat like floor tiles) b. Number of cell layer • Simple epithelium: a single layer of cells • Stratified epithelium: multiple tiers of cells • Pseudostratified

14. Epithelial Tissues • Simple Squamous Epithelium • Simple Cuboidal Epithelium • Simple Columnar Epithelium • Stratified Epithelium • Pseudostratified Columnar Epithelium • Transitional Epithelium

15. Classification of Epithelia

19. “ciliated” literally = eyelashes (see next page)

21. Stratified: regenerate from below

25. Glandular epithelia Some epithelia, called glandular epithelia because absorb or secrete chemical solutions. • Glands • Line the lumen of the digestive and respiratory tracts form a mucous membrane

26. Classification of glands • By where they release their product • Exocrine: external secretion onto body surfaces (skin) or into body cavities • Endocrine: secrete messenger molecules (hormones) which are carried by blood to target organs; “ductless” glands • By whether they are unicellular or multicellular

27. Exocrine glandsunicellular or multicellular Unicellular: goblet cell scattered within epithelial lining of intestines and respiratory tubes Product: mucin mucus is mucin & water

28. Multicellular exocrine glands Epithelium-walled duct and a secretory unit

29. Examples of exocrine gland products • Many types of mucus secreting glands • Sweat glands of skin • Oil glands of skin • Salivary glands of mouth • Liver (bile) • Pancreas (digestive enzymes) • Mammary glands (milk)

30. Endocrine glands • Ductless glands • Release hormones into extracellular space • Hormones are messenger molecules • Hormones enter blood and travel to specific target organs

32. Transitional

33. Transitional

34. Simple Cuboidal

35. Simple Squamous

36. Simple Columnar • Colon

37. Intestine

38. Duodenum

40. Connective Tissues • Loose Connective Tissue • Dense Connective Tissue • Adipose Tissue • Cartilage • Bone • Blood

41. TYPES OF CONNECTIVE TISSUE 1. True Connective Tissuea. Loose Connective Tissue b. Dense Connective Tissue 2. Supportive Connective Tissuea. Cartilage b. Bone 5. Liquid Connective Tissue a. Blood

42. Classes of Connective Tissue: note the cell types and great variety of subclasses

43. Connective tissue Functions mainly to bind and support other tissues. Three major components • Fiber collagenous fibers elastic fibers reticular fibers • Cell • Matrix
