Flashcards in LECTURE 1 connective tissue Deck (11):
1

types of connective tissue (4)

connective tissue proper, cartilage, bone tissue, blood

2

features of all connective tissue

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)

3

functions of connective tissue (5)

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

4

fibers in connective tissue (3)

reticular, collagen, elastic

5

reticular fiber

form network for structure and support, ex: cover capillaries

6

collagen fiber

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

7

elastic fiber

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

8

components of connective tissue (3)

fibroblasts, interstitial fluid, ground matrix

9

fibroblasts

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

10

interstitial fluid

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

11

ground matrix

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