5 Body Tissues (Cartilage)

Question 1

What are the main cell types in cartilage?

Answer 1

immature cells: chondroblasts

mature cells: chondrocytes

Question 2

what is the membrane surrounding cartilage called?

Answer 2

perichondrium

Question 3

describe the blood supply and nerve supply to cartilage

Answer 3

there is no direct blood supply to cartilage (avascular) and it is not innervated

cartilage relies on diffusion from surrounding tissues to obtain nutrients

this means that cartilage heals very slowly

Question 4

what are the 3 types of cartilage?

Answer 4

hyaline
fibrocartilage
elastic

Question 5

describe the features of hyaline cartilage

Answer 5

main cell type: chondrocytes

ECM: firm ground substance with collagen fibres

located in articulating surfaces of synovial joints, embryonic skeleton and epiphyseal plates, nose and trachea

supports, cushions and resists compression

Question 6

describe the features of fibrocartilage

Answer 6

main cell type: chondrocytes

ECM: firm ground substance with collagen fibres

located in IV discs, pubic symphysis, glenoid labrum, wrist

Question 7

describe the features of elastic cartilage

Answer 7

main cell type: chondrocytes

ECM: firm ground substance with elastic fibres

ear and epiglottis
