Q

Perichondrium

A

DCT capsule, covers some cartilages, contains BVs, nerves, fibroblasts, type I collagen, essential for growth/maintenance of some cartilage

Q

Territorial matrix

A

area directly surrounding isogenous groups, darker

17
Q

Interterritorial matrix

A

space between territorial matrix, lighter

18
Q

ECM component of Elastic cartilage

A

same as Hyaline, plus elastic fibers (more bendy than Hyaline)

19
Q

Location of Elastic cartilage

A

auricle, auditory canal, auditory tube, epiglottis

20
Q

Perichondrium of Hyaline cartilage

A

present

21
Q

Perichondrium of Elastic cartilage

A

present

22
Q

Appearance of Elastic cartilage

A

fresh: yellowish
histo: prominent elastic fibers with special stain

23
Q

ECM component of Fibrocartilage

A

type I collagen (like DCT), less proteoglycans than other cartilage (vvery very strong)

24
Q

Location of Fibrocartilage

A

intervertebral discs, pubic symphysis, major tendon-bone anchorages (areas that undergo pulling forces)

25
Q

Perichondrium of Fibrocartilage

A

absent

26
Q

Appearance of Fibrocartilage

A

looks like cross between DCT and hyaline cartilage, chondrocytes arranged in long rows separated by coarse collagen fibers, acidophilic matrix
