stimulate local inflammatory response

Question 25

loose CT wandering cells: what is the function of microphages

Answer 25

small phagocytic cells that assist during infection and tissue damage

Question 26

Areolar connective tissue - loose where is it found?

Answer 26

``` dermis (papillary layer hypodermis digestive respiratory between muscles around blood vessels nerves and joints ```

Question 27

Areolar connective tissue - loose what is its framework and what are its functions?

Answer 27

open framework- contains all cells and fibers found in CT proper cushions organs provides support but permits independent movement phagocytic cells provide defense

beneath skin- at abdomen, buttocks, breasts; around kidneys and other organs

Question 29

Adipose tissue -Loose CT functions?

Answer 29

protection, absorbs shock insulation reduce heat loss and stores energy

Question 30

reticular tissue- loose CT where is it found?

Answer 30

``` liver kidney spleen lymph nodes bone marrow ```

Question 31

reticular tissue- loose CT function?

Answer 31

provide support | framework- light but strong

Question 32

Dense connective tissue what are the 3 examples?

Answer 32

dense regular CT dense regular (elastic connective tissue) dense irregular CT

Question 33

Dense connective tissue functions?

Answer 33

firm attachments transmits forces reduces friction between muscles stabilizes relative position of bones

Dense irregular connective tissue what are its locations?

Answer 38

capsules of joints and visceral organs dermis of skin (reticular layer) periostea and perichondria Nerve and muscle sheaths

Question 39

Dense irregular CT Functions?

Answer 39

strength to resist forces applied from many directions helps prevent over expansion of organs
