Connective Tissue

Question 1

Connective tissue differs from other tissue in structure…

Answer 1

Mostly ECM with relatively few cells

Question 2

Cells of connective tissue: mesenchymal cells give rise to…

Answer 2

Fibroblasts and Lipblasts

Question 3

Fibroblasts

Answer 3

Most common cells in connective tissue proper

produce and maintain collagen and elsatin to form fibers

Synthesize and secrete components of ground substance

Question 4

Lipblasts

Answer 4

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)

Question 5

Macrophages

Answer 5

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

Question 6

Mast cells

Answer 6

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)

Question 7

ECM

Answer 7

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)

Question 8

Basement membrane

Answer 8

Specialized ECM that underlies all epithelial cells

Provides structural support

Question 9

Fibers made of collagen

Answer 9

Collagen

Reticular

Question 10

Fibers made of elastin

Answer 10

Elastic

Question 11

Collagen/ reticular fibers function

Answer 11

Impart tensile strength, provide supporting framework

Sheering/tearing forces

Question 12

Elastic fibers function

Answer 12

elasticity and resiliance

allows for deformation and recoil

Question 13

Fibrillar- Type I

Answer 13

Most abundant and widely distributed. Forms collagen fibers of ECM

Question 14

Fibrillar Type III

Answer 14

forms reticular fibers

Question 15

Fibrillar type IV

Answer 15

Network or sheet forming. Major strucural proteins of basement membrane

Question 16

Fibrillar type VII

Answer 16

linking/anchoring

anchors layers of basement membrane to eacother

Question 17

Reticular Fibers

Answer 17

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

Question 18

Answer 18

Reticular fibers

Question 19

Elastic Fibers

Answer 19

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

Answer 20

Elastic Fibers
