LECTURE 1 connective tissue

Question 1

types of connective tissue (4)

Answer 1

connective tissue proper, cartilage, bone tissue, blood

Question 2

features of all connective tissue

Answer 2

matrix, mostly made of extracellular material, never an apical side, most abundant tissue, contains a variety of cells and fibers, originates from mesenchyme (embryonic connective tissue)

Question 3

functions of connective tissue (5)

Answer 3

support and structure (#1 function), connecting, storing and carrying nutrients, protection, fight infection

Question 4

fibers in connective tissue (3)

Answer 4

reticular, collagen, elastic

Question 5

reticular fiber

Answer 5

form network for structure and support, ex: cover capillaries

Question 6

collagen fiber

Answer 6

strongest, most numerous, provide tensile strength against pulling forces, ex: dominant fiber in ligaments and tendons

Question 7

elastic fiber

Answer 7

long and thin, stretch and retain shape, ex: dominant fiber in elastic cartilage

Question 8

components of connective tissue (3)

Answer 8

fibroblasts, interstitial fluid, ground matrix

Question 9

fibroblasts

Answer 9

cells that produce all fibers in CT, produce and secrete protein subunits to make them, produce ground matrix

Question 10

interstitial fluid

Answer 10

derived from blood in CT proper; medium for nutrients, waste and oxygen to travel to cells; found in ground matrix

Question 11

ground matrix

Answer 11

part of extra-cellular material that holds and absorbs insterstitial fluid, made and secreted by fibroblasts, jelly-like with sugar and protein molecules
