Term
| what are the 4 types of connective tissue |
|
Definition
Connective tissue proper (loose and dense), Cartilage, bone and blood
"C.C.B.B" |
|
|
Term
|
Definition
the undifferentiated embryological connective tissue (common origin of all connective tissue)
NOTE: endothelium and mesothelium are also derived from mesenchyme |
|
|
Term
| What are the 6 functions of connective tissue? |
|
Definition
| Support, Bind, Storage, Transport, Protection and immune protection |
|
|
Term
| Explain how bone, cartilage and connective tissue proper serve as support. |
|
Definition
Bone: forms framework of body and acts as places for muscles to attach to.
Cartilage: forms frameworks for structures like the trachea and bronchi.
Connective tissue proper: forms capsules for organs |

Term
| what do bone and fat store? |
|
Definition
Bone: stores Ca and P
Fat: stores energy |
|
|
Term
| Which of the 4 connective tissues act as transport? |
|
Definition
|
|
Term
| Fat can act as protection to organs such as the spleen, true or false? |
|
Definition
| false, fat (perirenal fat) can act as a pocket of protection for the kidneys |
|
|
Term
| many connective tissues contain ___ to destroy pathogens |

Definition
|
|
Term
| What is the difference between loose and dense connective tissue proper? |
|
Definition
Loose: Few fibers, more ground substance
Dense: more fibers, less ground substance |
|
|
Term
| What are the 3 types of LOOSE connective tissue proper? |
|
Definition
| Areolar, Adipose and Reticular |
|
|
Term
| What is areolar tissue? What is it's function? |
|
Definition
Definition: a fairly undifferentiated (least specialized) and widespread design of connective tissue.
Function:hold water and surrounds capillaries (considered "packing" tissue") |
|
|
Term
| What is special about areolar connective tissue? |
|
Definition
| Thought of as the "prototype" for loose connective tissue proper because it has a sample of almost all the different types of cells and fibers found in other connective tissue |
|
|
Term
| Where can fibroblasts be found? |
|
Definition
|
|
Term
| What do fibroblasts produce |
|
Definition
| Protein fibres and ground substance |
|
|
Term
| What are the 3 types of fibers produced by fibroblasts? Arrange them from thickest to thinnest. |
|
Definition
| Collagen (white) > elastic (yellow) > reticular |
|
|
Term
| Name the traits and function of collagen (white) fibres |
|
Definition
trait: strong, flexible and resistant to stretch
Function: give connective tissue strength |
|
|
Term
| Name the traits and function of elastic (yellow) fibres |
|
Definition
Trait: Stretchy and recoil
Function: give connective tissue the ability to stretch and recoil |
|
|
Term
| Name the traits and function of reticular fibres |
|
Definition
Traits: tough but flexible, form branching network
Function: act like sponge and provide framework for softer organs (i.e. spleen or lymph nodes) |
|
|
Term
| What are reticular fibers made of |
|
Definition
| Made up of collagen protein (different than white fibers) |
|
|
Term
|
Definition
| Colourless, viscous solution |
|
|
Term
| what 3 types of cells can be found in areolar tissue |
|
Definition
| fibroblast, defence cell (macrophage) and adipose cells |
|
|
Term
| a defense cell is the 1st line of defense against a pathogen, True or false |
|
Definition
| False, epithelial cells are 1st, defense cells are second |
|
|
Term
| True or false, there are many types of defense cells |
|
Definition
| True, many different types of cells are each responsible in different ways for breaking down pathogen that enter the body |
|
|
Term
| Epithelial cells are avascular, true or false? |
|
Definition
| true, although most connective tissues have a blood vessels passing through them, epithelial tissue does not. |
|
|
Term
| What is the function of adipose cells? |
|
Definition
| Energy storage, pad and protect body, source of regulatory hormones (i.e. Leptin) |
|
|
Term
|
Definition
| tissue mainly composed of adipose (fat) cells |
|
|
Term
| where can adipose tissue be found |
|
Definition
| female breast and around some organs for protection and insulation (i.e. kidney) |
|
|
Term
|
Definition
| a mesh network consisting of mainly reticular type fibres |
|
|
Term
| where can reticular tissue be found |
|
Definition
| in hollow organs (i.e. spleen, liver, lymph nodes) to act like a sponge and trap fluids |
|
|
Term
| What are the 3 types of DENSE connective tissue? |
|
Definition
| Regular, irregular and elastic |
|
|
Term
| define: regular dense connective tissue |
|
Definition
| tissue in which the collagen fibers fun parallel with each other with poor blood supply making it hard to heal when damaged |
|
|
Term
| where can regular dense connective tissue be found? |
|
Definition
|
|
Term
| define: irregular dense connective tissue |
|
Definition
| tissue consisting of mainly collagen fires found in a irregular/meshwork pattern (sometimes mixed with elastic cells) |
|
|
Term
| where can irregular dense connective tissue be found? |
|
Definition
| dermis of skin, surrounding cartilage (perichondrium) and surrounding bone (periosteum) |
|
|
Term
| define: elastic dense connective tissue |
|
Definition
| connective tissue with collagen and elastic fires to allow for expansion and recoil |
|
|
Term
| where is elastic dense connective tissue found? |
|
Definition
| elatic ligaments (i.e. Ligamentum Nuchae) and the heart |
|
