Connective tissue Flashcards
features of connective tissues
characterised by an abundance of intercellular matrix with relatively few cells
immature cells
-blasts. secrete the matrix
mature cells
cyte-. maintain the matrix
connective tissue matrix
consists of protein fibres embedded in a ground substance. the makeup of the matrix gives each type of connective tissue its unique properties
function of protein fibres
give flexibility (elastin) and strength (collagen)
function of ground substance
supports cells, binds cells together and provides a medium for exchange
types of cartilage
hyaline, fibro and elastic
hyaline cartilage
covers articular surfaces at joints
reduces friction
absorbs shock
fibrocartilage
forms discs and rings between joints
great strength and some elasticity
can resist considerable pressure
made up of chondrocyte cells
types of deep connective tissue
dense regular (e.g. tendon), dense irregular (e.g. joint capsule), elastic (e.g. lungs)
dense regular connective tissue
provides strong attachment between structures and provides strength in one direction
matrix of collagen fibres
ligaments
connect bone to bone, restricting motion and stabilising joints
tendons
connect muscle to bone, allows movement
dense irregular connective tissue
provides strength in multiple directions
matrix of collagen fibres randomly arranged
deep fascia
sheet of connective tissue surrounding and protecting muscles
holds muscles together and separates them into functional groups
