Classification of connective tissue Dr Fraser Philp Intended learning outcomes Connective Tissue Describe the classification of different types of connective tissue Describe the structure and function of different types of connective tissue indicating their locations Identify differentiating features of connective tissue from Other principal tissues The different sub-classifications of connective tissue  Connective tissue - classification Embryonic Mature Loading… We will be focussing on the classification of Mature connective tissue Present at birth and persists through life 11 cells give rise to the cells of connective tissue Mesenchymal  Types of mature connective tissue 1. Connective tissue proper flexible and contains viscous ground 3 substance with abundant fibres 2. Supportive connective tissue protects and supports soft tissues of the body 3. Liquid connective tissue extra cellular matrix is liquid  Classification of mature 1. connective tissue 2. Types of connective tissue can be broadly classified into 5 types 1. Loose connective tissue 2. Dense connective tissue Loading… 3. 3. Cartilage 4. Bone tissue 4. 5.

Considerably less cells than loose connective tissue Cartilage has a higher proportion of collagen fibres with a gel like components of the ground substance. Can endure more stress than loose or dense connective tissue Bone tissue can be compact or spongy, dependant on extracellular matrix  Dense regular connective tissue Further reading Principles of anatomy and physiology / Gerard J.
