Flashcards in Connective Tissue Deck (31):
1

Connective tissue differs from other tissue in structure...

Mostly ECM with relatively few cells

2

Cells of connective tissue: mesenchymal cells give rise to...

Fibroblasts and Lipblasts

3

Fibroblasts

Most common cells in connective tissue proper

produce and maintain collagen and elsatin to form fibers

Synthesize and secrete components of ground substance 

4

Lipblasts

give rise to adipocytes (fat cells) specialized for cytoplasmic storage of lipid

Tissue with large population of adipocytes also serves to cushion and insulate (skin, kidney) 

5

Macrophages

Specialize in removal od dead cells and tissue debris 

can activate immune system and promote inflammatory response 

also secrete enzymes to break down dead tissue and growth factors to promote their repair and healing

6

Mast cells

type of immune cell which stores chemical mediators important in localized immune response and tissue repair

often located near blood vessels, in tissue lining digestive and respiratory tract (areas where threats can be detected) 

7

ECM

Contains structural proteins (collagen and elastin fibers) embedded in viscious gel made up of protein-polysaccharide complexed (proteoglycans) water, and adhesive glycoproteins that bind to matrix proteins and cell membrane proteins (laminin, fibronectin)

8

Basement membrane

Specialized ECM that underlies all epithelial cells 

Provides structural support 

9

Fibers made of collagen

Collagen

Reticular 

10

Fibers made of elastin

Elastic 

11

Collagen/ reticular fibers function

Impart tensile strength, provide supporting framework

Sheering/tearing forces 

12

Elastic fibers function

elasticity and resiliance

allows for deformation and recoil

13

Fibrillar- Type I

Most abundant and widely distributed. Forms collagen fibers of ECM

14

Fibrillar Type III

forms reticular fibers

15

Fibrillar type IV

Network or sheet forming. Major strucural proteins of basement membrane

16

Fibrillar type VII

linking/anchoring 

anchors layers of basement membrane to eacother 

17

Reticular Fibers 

Form a delicate network of thin fibers that provide supportive stroma for bone marrow, lymph nodes, organs including liver and spleen

19

Elastic Fibers 

Form sparse networks interspersed with collagen bundles in tissue subject to stretching or bening (skin, vertebral ligaments, elastic arteries, vocal cords)
