Q

What are the functions of connective tissue?

A

CONNECTS: form tissues, organs, TRANSPORTS: medium for diffusion of nutrients/wastes, PROTECTS: cushion between, insulation, STORAGE: adipose, DEFENCE: against infection, WOUND HEALING: fibroblasts

Q

What are the specialised types of CT?

A 
– Adipose
– Lymphatic
– Blood
– Haemopoietic
– Cartilage
– Bone
17
Q

How would CT be divided into its types?

A

CT = PROPER (dense = regular, irregular, elastic) (loose = areola, adipose, reticular). FLUID (blood) (lymph). SUPPORTING (bone) (cartilage = hyaline, elastic, fibrous)

17
Q

What is a ligament?

A

CT that connects bone to bone

18
Q

What is a tendon?

A

CT that connects bone to muscle
