Term
| what are the 4 types of membranes? |
|
Definition
| Skin, Mucous, Serous and synovial |
|

|
Definition
|
|
Term
| cutaneous membrane is another way of saying ____ |
|
Definition
|
|
Term
|
Definition
| an epithelial layer over a layer of loose connective tissue with mucous producig goblet cells between epithelial layers |
|
|
Term
| where can mucous membranes be found? |
|
Definition
| inner linings of hollow organs that are exposed to external environments (i.e. respiratory, urinary, reproductive and digestive systems) |
|
|
Term
| True or false, membranes may differ in type of epithelial tissue depending on the location |
|
Definition
|
|
Term
|
Definition
| a thin and delicate membrane made up of simple squamous epithelial tissue over a layer of areolar connective tissue |
|
|
Term
| function: serous membrane |
|
Definition
| produce thin watery fluid that prevents friction when internal abdominal organs move |
|
|
Term
| Where can serous membranes be found? |
|
Definition
| lining of plural, pericardial and peritoneal cavity as well as the lungs, heart and digestive system |
|
|
Term
| define: synovial membrane |
|
Definition
| synovial epithelial cells over loose connective tissue |
|
|
Term
| True or false, synovial membranes are a type of epithelial lining that is not continuous (like most epithelial linings are) and is therefore often discredited for being a "true membrane" |
|
Definition
|
|
Term
| Where are synovial membranes located |
|
Definition
| inner lining of joint capsules in most freely movable joints |
|
|
Term
| what is the function of the synovial fluid secreted by the synovial membrane? |
|
Definition
| to lubricate and protect the joint as well as provide nutrients to the cartilage within the joint |
|
|
Term
| Cartilage is known as a solid matrix, true or false |
|
Definition
| False, Bone is considered a solid matrix. Cartilage is a semi-solid matrix |
|
|
Term
| What are the 2 cells found in cartilage? |
|
Definition
| Chondroblasts and chrondrocytes |
|
|
Term
|
Definition
| Cartilage forming cells that produce collagen and elastic fibres as well as cartilaginous ground substance. (The cartilage version of a "fibroblast") |
|
|
Term
|
Definition
|
|
Term
| What is the function of ground substance in cartilage |
|
Definition
| to allow the cartilage to be solid but pliable |
|
|
Term
|
Definition
| Outer dense connective tissue propper layer covering cartilage |
|
|
Term
| What are the 3 types of cartilage? |
|
Definition
| Hyaline cartilage, fibrocartilage and elastic cartilage |
|
|
Term
| What is the most common type of cartilage, why is it the most common and what is it formed of? |
|
Definition
| Hyaline cartilage is the most common cartilage because it is the precursor to the skeletal system. It is made of a high concentration of fine/thin collagen fibers. |
|
|
Term
|
Definition
|
|
Term
| Define: articular cartilage |
|
Definition
| Hyaline cartilage that is located on epiphysis, giving it a smooth "glassy" surface |
|
|
Term
| Where can hyaline cartilage be found? |
|
Definition
| anterior end of ribs where they join the sternum and as articular cartilage at the epiphysis |
|
|
Term
| Articular cartilage is the only hyaline cartilage that does not have perichondrium, true or false? |
|
Definition
|
|
Term
| define: elastic cartilage |
|
Definition
| Cartilage similar to hyaline cartilage but with more elastic fibers allowing the cartilage to be more flexible and relilient |
|
|
Term
| elastic cartilage does not have a perichondrium, true or false |
|
Definition
|
|
Term
| where can elastic cartilage be found? |
|
Definition
| ears and epiglottis of larynx |
|
|
Term
| which type of cartilage lacks the most ground substance? |
|
Definition
|
|
Term
| in fibrocartilage, collagen fibres and chondrocytes are arranged in parallel rows, true or false? |
|
Definition
|
|
Term
| where can fibrocartilage be found? |
|
Definition
| intervertebral discs and menisci of the knee |
|
|
Term
| What is the function of fibrocartilage? |
|
Definition
| to absorb shock and resist compression |
|
|
Term
| why does fibrocartilage NOT have a perchondrium? |
|
Definition
| because the compression would damage the this layer |
|
