What does connective tissue form?
A huge continuum throughout body
What is the role of connective tissue?
NAME?
What are the functions of blood?
NAME?
What are the functions and cartilage?
Solid skeletal functions
Give 6 functions of connective tissues
- Provide substance and form to body and organs
- Provide medium for diffusion or nutrients and wastes
- Attach muscle to bone, and bone to bone
- Provide cushion between tissues and organs
- Defend against infection
- Injury repair
What happens to the immune cells produced in bone marrow?
NAME?
What part of connective tissue is particularly important in injury repair?
Fibroblasts
What do fibroblasts do?
Lay down new cellular matrix
What are the two main cellular tissue components?
- Cells
- Extracellular matrix
Is extracellular matrix present in all connective tissues?
Many, but not all
What makes extracellular matrix?
Cells
What does extracellular matrix consist of?
- Ground substance
- Fibres
What makes up ground substance?
Hyalurone proteoglycan aggregates
What fibres are found in the extra cellular matrix?
- Collagen
- Reticular
- Elastic
What do connective tissues differ in terms of?
- Types of cell they contain
- Abundance / destiny of their cells
- Constitution of the extra cellular matrix
What does the constitution of the extra cellular matrix differ in terms of?
- Ground substance composition
- Fibre type, abundance and arrangement
What are the 3 classifications of connective tissue?
NAME?
What are the embryonic connective tissues?
- Mesenchyme
- Mucous connective tissue
What are the regular connective tissues?
- Loose connective tissue
- Dense connective tissue
What are the types of dense connective tissue?
- Regular
- Irregular

- Adipose
- Blood
- Cartilage
- Bone
- Lymphatic
- Haemopoietic
What forms mesenchyme in the early embryo?
Mesodermal cells from the embryonic germ layer andfew ectodermal cells migrate and proliferate to form mesenchyme
What does mesenchyme consist of?
Multipotent progenitor cells
