Term
Define: membrane
Definition
epithelial cells + connective tissue
Term
what are the 4 types of membranes?
Definition
Skin, Mucous, Serous and synovial
Term
define: Epethelium
Definition
outer layer of epidermis
Term
define: connective tissue
Definition
deeper layer of dermis
Term
cutaneous membrane is another way of saying ____
Definition
skin
Term
define mucous membrane
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
true
Term
define: serous membrane
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
True
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
Define: condroblast
Definition
Cartilage forming cells that produce collagen and elastic fibres as well as cartilaginous ground substance. (The cartilage version of a "fibroblast")
Term
Define: Chondrocyte
Definition
a cartilage cell
Term
What is the function of ground substance in cartilage
Definition
to allow the cartilage to be solid but pliable
Term
define: Perichondrium
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
Define: Epiphysis
Definition
the ends of a long bone
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
true
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
false
Term
where can elastic cartilage be found?
Definition
ears and epiglottis of larynx
Term
which type of cartilage lacks the most ground substance?
Definition
fibrocartilage
Term
in fibrocartilage, collagen fibres and chondrocytes are arranged in parallel rows, true or false?
Definition
true
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
