connective tissue Flashcards
function of connective tissue and examples of connective tissue
provides structural/functional support
ex- bone, cartilage, tendons, ligaments, adipose tissue, mesentery
identify the 3 main components of a)connective tissue and b) extracellular matrix
a) cells, fibres and ground substance
b) ground substance and fibres
describe ground substance of connective tissue
. provides biochemical support
. allows cells to communicate
. consisits of glycoproteins and complex carbs (hyaluronic acid and glucosamine)
describe the fibres of connective tissue
. provide structural support and tesile strength
. collagen- strongest most abundant fibre produced by ECM
. elastin- provide stretch and produced by fibroblasts
function of connective tissue cells
synthesise/secrete/breakdown ECM
identify the 2 types of connective tissue proper and their differences
connective tissue loose (fewer fibres, more ground substance) and connective tissue dense (more fibres, less ground substance)
state 3 types of connective tissue loose and their main function
. areolar tissue- packaging material
. adipose- shock absorbtion, energy, insulation
. reticular- internal structure to higly celluar organs
state 3 types of connective tissue dense and their main function
. dense regular- closely packed collagen in same direction
. dense irregular- closely packed interwoven fibres in diff directions
. elastic- stretch/recoil
name some connective tissue disorders and describe their oral manifestaions
Scurvy
. lack vit C leading to deffective collagen
. lose teeth
Systemic lupus erythematosis (SLE)
. autoimmune disease
. oral dryness, bucal & palatal lesions
Sjorens
. autoimmune affecting tear and saliva glands
. dry mouth, caries and candiasis
connective tissue can be divided into 4 types, what are these?
- connective proper (loose or dense)
- cartilage
- bone
- blood
