What are the functions of connective tissue? | Binds and supports tissues. Insulates and protects organs. Major transport system in the body - blood. Energy store - fat (adipose tissue). Immune function. |
The two elements of connective tissue are: | Connective tissue cells Extra cellular matrix (material between the cells). |
Cartilage is | firm but pliable |
Two different types of connective tissue? | Cartilage and bone |
Bone is | hard and not pliable |
Is connective tissue highly vascular? | Yes |
Connective tissue cells? | Fibroblasts Macrophages Plasma cells Mast cells Adipocytes |
Fibroblasts | Synthesise fibres |
Macrophages | defence function. Engulf bacteria and debris. |
Plasma cells | defence/immune function. Secrete antibodies. |
Mast cells | Produce histamine. Dilate blood vessels. |
Adipocytes | Fat cells. Energy storage. |
Collagen fibres are found in ? | Bone, tendons, cartilage, ligaments. |
Elastic fibres are found in? | The skin, blood vessel walls, lung tissue. |
Collagen contains the protein? Elastic fibres contain the proteins? Reticular fibres contain the protein? | Collagen. Elastin and Fibrillin. Collagen. |
Reticular fibres are found | In the walls of blood vessels, around fat cells, nerve fibres and muscle tissue. |
Areolar connective tissue is found in | the subcutaneous layer of the skin. |
Cartilage is made up of | collagen and elastic fibres. |
Cartilage cells are called? | Chondrocytes |
Cartilage has a blood supply? | No |
3 types of cartilage. | Hyaline Fibro Elastic |
Chondrocytes sit in small spaces called? | Lacunae. |
Where is fibrocartilage found? | Intervertebral discs |
Hyaline cartilage is found in? | Ends of long bones, ribs, nose |
Elastic cartilage is found in | larynx (Epiglottis), ear and auditory tubes. |
Types of cells in bone? | Osteogenic cell (develops into an osteoblast) Osteoblast (forms bone extracellular matrix) Osteocyte (maintains bone tissue) Osteoclast (functions in reabsorption, the breakdown of bone matrix) |
