– responsible for providing and maintaining form


CONNECTIVE TISSUE

2

-made up mainly of non-living material, extracellular matrix

CONNECTIVE TISSUE

3

-matrix: physically links cells and tissues, gives mechanical support to the different organs

CONNECTIVE TISSUE

4

-contains blood vessels and nerves; serves the needs of avascular epithelium

CONNECTIVE TISSUE

5

CT component
CT Cells originate from -----------------

precursor cells in primitive mesenchyme

6

ct fibers are made up of

proteins and polysaccharides

7

most abundant protein in the human body

collagen

8

-key element of all CT, basement membrane, external laminae of muscles and nerve cells

collagen

9

-synthesizes collagen and reticular fibers

collagen

10

CT fiber
may be arranged as parallel fibers or discontinuous sheets
-has properties of stretching and elastic recoil

elastin

11

GS is hydrophobic or hydrophilic

hydrophilic

12

-form a medium for the passage of molecule throughout supporting tissues

ground substance

13

-for the exchange of metabolites with the circulatory system

ground substance

14

-gel-like: serves as lubricant, barrier to invasive microorganism

ground substance

15

embryonic CT which originates from the mesoderm and neural crest ectoderm

1. Mesenchymal CT

16

Mesenchymal CT originates from?

mesoderm and neural crest ectoderm

17

fibers of Mesenchymal CT

uniformly distributed sparse collagen fibers (reticular type)

18

cells of Mesenchymal CT

undifferentiated mesenchymal cells (a homogenous population of cells but may also have stem/progenitor cells)

19

transient type of tissue

mucoid CT

20

LOCATION OF MUCOID CT

-location: umbilical cord and fetal organs

21

-matrix of mucoid ct


jelly-like

22

-fibers: mucoid ct

delicate network of collagen fibers

23

-cells:mucoid ct

scattered star-shaped fibroblasts (w/ flattened processes that appear to fuse with neighboring cells)

24

-ground substance: mucoid ct

soft, very abundant, appears homogenous in fresh state, composed chiefly of hyaluronic acid

25

-residue: contains granules and fibrillar precipitates when fixed; exhibits staining reactions of mucin

mucoid CT

26

– most widely distributed CT




1. Loose/Areolar CT

27

CT found in almost every microscopic section of the body

1. Loose/Areolar CT

28

-fills up empty spaces

1. Loose/Areolar CT

29


-serves as packing and anchoring material

1. Loose/Areolar CT

30

-supports epithelium where it encompasses the lamina propia (thick layer beneath the epithelial lining of stomach and intestines)

1. Loose/Areolar CT
