connective tissue

Question 1

what are the 3 types of connective tissue(CT)

Answer 1

soft connective tissue
hard connective tissue
blood and lymph

Question 2

what does connective tissue consist of

Answer 2

an extracellular matrix= made up of fibres(collagen, elastic, reticular), ground substance,tissue fluid
cells = fibroblasts, adipose, osteocytes(bones), chondrocytes(cartilage)

Question 3

what are the different types of soft connective tissue

Answer 3

loose, dense regular CT or dense irregular CT

Question 4

what is loose connective tissue made up of

Answer 4

elastic fibres, bundles of collagen(light orange), fibroblasts

Question 5

what is the difference between dense regular and irregular CT

Answer 5

both made up of densely packed bundles of collagen(light pink) and fibroblasts
difference = regular the fibres are aligned, irregular the fibres run in many directions

Question 6

what are the 2 types of hard connective tissue

Answer 6

cartilage and bone

Question 7

what are the properties of cartilage and what causes them

Answer 7

strong, flexible, compressible, semi-rigid tissue
semi-rigid nature due to highly hydrated ground substance
it is avascular and receives nutrients by diffusion through matrix

Question 8

what are the 3 types of cartilage, and which is most common

Answer 8

hyaline, elastic and fibrocartilage
type is defined by the extracellular matrix
most common =hyaline(articular surface, trachel rings etc.)

Question 9

what are the 2 types of bone tissue and what do they make up

Answer 9

cortical bone makes up shaft

cancellous/trabecular bone occupies ends of the bone(epiphyses, looks like fine meshwork(aero bar)
