connective tissue: test 1

Question 1

what are the general features of connective tissue?

Answer 1

1) Consist of cells surrounded by a matrix
2) Matrix may be fluid, semi-fluid, gelatinous, fibrous, calcified matrix gives the tissue its consistency.
3) Matrix is made by the cells then they live in it.
4) Doesn’t occur on free surfaces (except in joints)
5) Has a nerve supply
6) Has a blood supply

Question 2

which type of connective tissue cells secrete matrix?

Answer 2

fibroblasts

Question 3

Answer 3

macrophages

Question 4

immune cells, make antibodies, type of lymphocyte. which type of connective tissue cells is this?

Answer 4

plasma cells

Question 5

immune cells, creates histamine, and causes swelling, is which type of connective tissue cells?

Answer 5

mast cells

Question 6

which type of connective tissue cells are fat storage cells?

Answer 6

adipose cells

Question 7

various white blood cells of the immune system fight infections, is which type of connective tissue cells?

Answer 7

leukocytes

Question 8

what is a non-cellular material surrounding the cells gives connective tissue shape and consistency made by fibroblasts made of ground substance?

Answer 8

connective tissue matrix

Question 9

what is ground substance?

Answer 9

are molecules made of protein and polysaccharides. 4 ground substance molecules are in the matrix.

1. hylauronic acid
2. chondroitin sulfate
3. dermatin sulfate
4. keraton sulfate.

Question 10

what is hylauronic acid?

Answer 10

viscous and slippery. ex- lubrication in joints, and in the eyeball

Question 11

what is chondroitin sulfate?

Answer 11

jelly like Ex- in cartilage, bone, and skin.

Question 12

what is dermatin sulfate?

Answer 12

stronger, tough, not stiff, flexible. Ex- tendons and blood vessels

Question 13

what is keraton sulfate?

Answer 13

hard and strong. Ex- bone and fingernails

Question 14

what gives matrix strength, shape or elasticity.

Answer 14

Fibers

Answer 15

collagen

Question 16

which type of fiber forms a mesh to give a tissue shape?

Answer 16

reticular fibers

Question 17

which type of fiber allows tissue to stretch?

Answer 17

elastic fibers

Question 18

which type of connective tissue has fewer fibers so matrix has “space” for cells and ground substances?

Answer 18

Loose connective tissue

Question 19

what type of connective tissue matrix has all 3 fibers and all 4 ground substance molecules. Acts as a packing material in organs and tissues. Cushions tissue. Ex- subcutaneous layer under skin

Answer 19

Areolar connective tissue

Question 20

what type of connective tissue fat tissue’s Major cell type is adipose cells. Very few fibers. Stores fat. Acts as armor for organs (protect). Fill out spaces?

Answer 20

adipose tissue

Question 21

what type of connective tissue has lots of reticular fibers, Makes internal structure of organs?

Answer 21

Reticular connective tissue

Question 22

what type of connective tissue has lots of fibers, Room for cells or ground substance?

Answer 22

Dense connective tissue

Question 23

what type of connective tissue has all fibers run in the same direction. Ex- tendons. Strong in fiber direction, weak perpendicular to fiber direction?

Answer 23

Dense regular connective tissue

Question 24

what type of connective tissue has lots of fibers ging in all directions. Strong in every direction. Ex- dermis of the skin?

Answer 24

Dense irregular connective tissue

Question 25

what type of connective tissue has lots of elastic fibers for stretchy tissues? Ex- arteries

Answer 25

Elastic connective tissue

Question 26

what is stiff, inflexible connective tissue and strong solid matrix with holes (lacuna) for cells (chondrocytes)?

Answer 26

cartilage

Question 27

which type of cartilage is the most common cartilage. weakest type? Ex- in joints between some bones, between ribs and sternum, nose.

Answer 27

hyaline cartilage

Question 28

which type of cartilage contains lots of collagen fibers. Strongest cartilage and the Least flexible? Ex- pubic symphysis, intervertebral discs.

Answer 28

fibrocartilage

Question 29

which type of cartilage has lots of elastic fibers. Most flexible cartilage? Ex- pinna of ear (auricle)

Answer 29

elastic cartilage

Question 30

what is oseus tissue?

Answer 30

bone

Question 31

what is the term for: an epithelial tissue over a connective tissue?

Answer 31

epithelial membrane

Question 32

what is a mucous membrane?

Answer 32

epithelial membrane
lining open cavity
has single cell glands to secrete liquid to keep membrane moist.

Question 33

what is serous membrane?

Answer 33

epithelial membrane lining a closed cavity has 2 layers:
1. parietal layer
2. visceral layer
between the layers is serous fluid.

Question 34

which layer of the serous membrane lines the cavity?

Answer 34

parietal layer

Question 35

which layer of the serous membrane wraps each organ?

Answer 35

visceral layer
