Connective tissue

Connective tissue is made up of:

Concerning the types of fibres found in connective tissue: [blank_start]Collagen[blank_end] fibres have high tensile strength. [blank_start]Elastin[blank_end] fibres give stretch and recoil. [blank_start]Reticular[blank_end] fibres form a mesh/network around organs.

Complete the paragraph to correctly describe the functions of some of the main cells found in connective tissue. [blank_start]Fibroblasts[blank_end] produce fibres. [blank_start]Chondroblasts[blank_end] build cartilage, [blank_start]Osteoblasts[blank_end] build bone. [blank_start]Macrophages[blank_end] carry out phagocytosis. [blank_start]Plasma cells[blank_end] produce antibodies. [blank_start]Mast cells[blank_end] produce histamine,

Another name for articular cartilage is [blank_start]hyaline[blank_end] cartilage

Match up the type of cartilage with the place in the body. [blank_start]Articular[blank_end] carilage - Ends of bones and joints [blank_start]Elastic[blank_end] cartilage - within blood vessel walls [blank_start]Fibrocartilage[blank_end] - pubic symphysis

The process by which biomechanical forces regulate cell activity to control the orientation of fibres within connective tissue is known as

Identify any facts that are true about articular cartilage

The ground substance is made up of:

he cells in cartilage which produce collagen fibres are called chondroblasts - a type of fibroblast. Within the ground substance there GAG chains. GAGS chains are [blank_start]negatively[blank_end] charged and therefore attract positively charged [blank_start]cations[blank_end]. This creates an [blank_start]osmotic[blank_end] gradient which draws water towards the GAG chains. This means that cartilage has a high [blank_start]water[blank_end] content. Due to the fact that the GAG chains are negatively charged, the chains repel each other which creates an internal [blank_start]pressure[blank_end]. When cartilage is put under tension, for example in the movement of a joint, the GAG chains are forced closer together. This forces water out of the cartilage tissue and into the [blank_start]synovial[blank_end] fluid. The water that leaves cartilage contains any waste products (e.g carbon dioxide). As the tension is reduced the GAG chains will spring back to their original position. This draws water back into the cartilage and brings with it dissolved oxygen and nutrients. This process is known as [blank_start]hydrokinetic transport[blank_end] or synovial sweep. This process is essential for supply of oxygen and nutrients due to the fact that cartilage does not have it's own [blank_start]blood[blank_end] supply.

Which are the following statements are true regarding the effects of movement on connective tissue?

Connective tissue is visco-elastic. This means that it's pliability is dependent on temperature.
