ground substance ECM

2

what stains black with silver salts

reticular fibers

3

what are coiled branched fiber

elastic fibers

4

what contains a single large fat droplet

white adipose tissue

5

what arises from myeloid stem cells in bone marrow and are usually near small blood vessels

mast cells

6

what arephagocytosingcellsofconnectivetissue.They are responsible for removing large particulate matter and assisting in the immune response. They also secrete substances that function in wound healing.

macrophages

7

arise from lymphoid stem cells during hemopoiesis

lymphoid cells

8

areantibody-manufacturingcellsthatarisefromactivatedBlym-
phocytes and are responsible for humoral immunity.

plasma cell

9

are white blood cells that possess cytoplasmic granules and arise from myeloid stem cells during hemopoiesis.

granulocytes

10

s a loose connective tissue that is the main constituent of the umbilical cord. It consists of a jellylike matrix with some collagen fibers in which large stellate fibroblasts are embedded.

mucous tissue Wharton's Jelly

11

embryonic CT

mucous connective tissue and mesenchymal tissue

12

has few fibers but more cells then dense CT

well vasculairzed
flexible
not resistent to stress

areolar ct (loose)

13

contains more fibers but fewer cells than loose connective tissue.

Dense CT

14

which contains fiber bundles that have no definite orientation. This tissue is characteristic of the dermis and capsules of many organs.

dense irregular

15

which contains fiber bundles and attenuated fibrob- lasts that are arranged in a uniform parallel fashion.
only in tendons and ligaments

dense regular

16

is composed of coarse, branching elastic fibers with a sparse network of collagen fibers and some fibroblasts filling the interstitial spaces. It

in
dermis
lungs
elastic cartilage
elastic ligaments

elastic tissue

17

consists mostly of a network of branched reticular fibers

reticular tissue

18

5 types of CT proper

areolar
dense
elastic
reticular
adipose

19

is composed of multilocular adipose cells, which contain many large mitochondria.

brown adipose tissue

20

This tissue is found in infants (also in hibernating animals) and is much reduced in adults.

brown adipose tissue

21

specialized CT consist of what two things

cartilage
bone
blood
