- 14 types of supporting tissues are:1. Loose CT
2. Tendons and ligaments
3. Dermis
4. Bone + Cartilage - 2What is Loose CT sometimes known as?Alveolar CT
- 3RESIDENT CELLS of LOOSE CT (5)1. Fibroblasts
2. Fat cells
3. Mast cells
4. Endothelial cells
5. Pericytes - 4Which one makes ECM?Fibroblast
- 5Which is involved in injury signalling?Mast cells
- 6Which are CT stem cells?Pericytes
- 7IMMIGRANT CELLS (4)Monocytes
Macrophages
Lymphocytes
Plasma cells - 8Dense Fibrous CT types (2)Regular
parallel Col. fibres
Irregular
disorganised col. fibres - 9What are the types of cartilage?Hyaline
Elastic
Fibro - 10Where is Hyaline cartilage found?Joint surface in adults
Foetal skeleton
Tracheal rings - 11Hyaline cartilage histologyOuter fibrous perichondrium
Inner chondrogenic layer
Chondrocyte
Matrix rich in GAGS - 12What are the 2 ways in which chondrocytes can grow?Form cell nests
AIG from inner chondronogenic layer cells - 13What does AIG mean?Appositional
Interstitial
Growth - 14What are the 4 zones of collagen architectureArticular zone
Tangenital zone
Transitional zone
Radial zone - 15What part is pumped with pressure and why?Subchondral bone
As GAGS and PG found here - 16How do collagen fibres transmute pressure changes?As matrix in subchondral bone swell
arcades of collagen fibres push against the articular zone - 17Where do collagen arcades resist stress?At the surface, pushing against the articular zone
- 18Where is elastic cartilage found?Pinna of ear
- 19What is Fibrocartilage?IM btw. hyaline cartridge + DFGT
- 20Features of fibrocollagen Where it's found (2)High GAGS content
Found in invertebral disks - 21What are the types of CT?Loose CT
DFCT - 22Bone cells diagram (3)Blast on surface
Cyte within
Clast outside - 23What are the two types of ossification?Intramembranous ossification
Endochondral ossification - 24What is mesenchyme?Embryo CT
- 25What conditions like in mesenchyme?Cells in sparse ECM
Vascular - 26Process of intramembranous ossificationCondensation
Differentiation
Without cartilage - 27What kind of growth is this?APPOSITION
- 28Diagram of this pls.remember cell processes.
Thank u - 29Process of Endochondral ossification in mesenchymeCONDENSATION
DIFFERENTIATION into different CHONDROCYTES
CARTILAGE MATRIX SECRETION - 30Diagram of this as well pls.epi
dia
epi - 31wHAT IS the 1' centre of ossification?Diaphysis
- 32What is the 2' centre of ossification?Epiphysis
- 33Why is this skele needed?Give structure in embryo
- 34Why don't embryos need full skeles?Cos they're floatn about in womb
- 35Diagram of epiphyisal growth plates pls with annotationsProliferation w/in longitudinal place leading to HYPERTROPHY
- 36Big boi diagram now of cells in epiphysisResting cells
