Connective Tissues Flashcards
Functions (4 points)
- binds together and supports other tissue
- protects and insulates organs
- compartmentalises structures
- is the bodies major transport system (blood)
Connective tissue is made up of? (3 points)
- ground substance
- fibres
- cells
What makes up the extracellular matrix?
- ground substance
- fibres
What is ground substance? (2 points)
- the material that supports the cells and fibres
- plays an active role in how tissue develops, migrates and proliferates
What is ground substance? (3 points)
- a liquid (blood)
- a gel (loose under skin)
- very hard (bone)
What do protein fibres do?
Support the connective tissue
What are the three types of protein fibres ?
- collagen (provide toughness and strength)
- elastic (provide strength and recoil)
- reticular (provide support and attachment)
What is an osteocyte?
Mature cells found in bone
What is a chondrocyte?
Mature cell found in cartilage
What is an adipocyte?
Mature cell found in adipose (fat) tissue
What is a fibroblast?
A immature cell that produces fibres
What is a cardiomyocyte?
A mature cell found in the heart muscle
What are erythrocytes?
Mature cells found in blood
What are the three types of loose connective tissue?
- areolar
- adipose
- reticular
What are the three types of dense connective tissue ?
- dense regular (collagen)
- dense irregular (collagen)
- dense regular (elastic)
What are the fibres in cartilage?
- collagen and elastic fibres
What is the ground substance of cartilage?
Chondroiton sulphate (a gel like component)
What are the 3 types of cartilage?
- hyaline
- fibrocartilage
- elastic
What are the two other types of tissue ?
- blood and bone
What are the three types of muscle tissue?
- skeletal
- cardiac
- smooth
Where is smooth muscle tissue?
Walls of hollow internal structures of the body
