- 1What is the importance of Supportive CT?It helps maintain posture and protects internal organs
- 2What are the two types of Supportive CT?1. Cartilage
2. Bone - 3What is Cartilage?A form of fibrous CT
- 4What is cartilage composed of?Composed of closely packed collagenous fibres which are embedded in a gelatinous substance called chondrin
- 5What is the main cell type which composes the cartilage?Chondroblasts
- 6Where is cartilage found? (4)1. Nose
2. Ears
3. Knee
4. Trachea - 7Describe the physical properties of CartilageCartilage is solid, flexible and avascular
- 8Give a reason why cartilage injuries take so long to healThis because nutrients must diffuse through the tissue
- 9what are the three main types of cartilage?1. Hyaline Cartilage
2. Fibrocartilage
3. Elastic Cartilage - 10Where would Hyaline Cartilage be found?This is the most common type and occurs around the ribs, nose and covers bones where they meet to from moveable joints.
- 11Describe the physical properties of Hyaline CartilageIt's strong and flexible
- 12What is Hyaline Cartilage composed of?It consists of short, dispersed collagen fibres and a large amount of proteoglycans in the ground substance
- 13Where could Fibrocartilage be found?It occurs in the knee joint and disks of vertebrae
- 14What is Fibrocartilage composed of?Fibrocartilage contains thick bundles of collagen fibres in it's matrix
- 15Describe the physical properties of FibrocartilageAs a results of it's structure it's very tough
- 16Where could Elastic Cartilage be found?The ear love contains elastic cartilage
- 17What is Elastic Cartilage composed of?Elastic Cartilage contains elastic fibres as well as collagen fibres
- 18What is the hardest of CT?Bone
- 19What is the role of bone?Bone provides support, strength, rigidity and protection
- 20What is meant by bone being a mineralised CT?It contains mineral deposits primarily calcium salts in extracellular matrix --> Calcium phosphate
- 21What does bone consist of?Bone contains collagen fibres in a matrix consisting of a mineralised ground substance containing calcium phosphate
- 22What is the importance of collagen fibres and minerals in the bones structureThe collagen fibres provide some flexibility while the minerals provide support
- 23What are the main cell types in bone?Osteoblasts and Osteoclasts
- 24What about bone allows it to repair itself relatively quickly?Bone contains a vast network of blood vessels
- 25What is different about the Fluid CT Bloods structure compared to other CT?Blood's extracellular matrix lacks insoluble protein fibres but has a variety of soluble proteins and it's matrix is made up of plasma
- 26What blood cells are suspended in the matrix of blood? (3)1. Erythrocytes
2. Leucocytes
3. Thrombocytes - 27What is the role of Red Blood Cells?Transports Oxygen, Nutrients and Waste to and from tissue cells
- 28What is the role of white blood cells?White blood cells defend against pathogens
- 29What is the role of platelets?Platelets aid in the clotting of blood
- 30What is the Fluid CT Lymph composed of?Lymph contains white blood cells and a liquid matrix
- 31What is the role of lymph?1. Lymph transports fats from the intestine to the blood
2. Excess fluid around cells also drain into lymph vessels, which in turn drain into blood vessels.
