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 |
