Connective Tissue Flashcards
What are Connective Tissues?
Deep tissues not exposed out of body, support and bind other tissues
store nutritional substance
most diverse
What are the 3 layers of the skin?
- Superficial Facia - between skin and organs, hypodermis
- Deep Fascia - strong fibrous framework, dense tissue
- Subserous Fascia - areolar tissue
What does Connective tissue do?
Derived from Mesoderm, Vary in structure and fuction, Highly Vascularised, Cell Adhesion, Replication and Repair
What are the 3 Basic Components of Connective tissue?
Specialised cells- fibroblasts
Protein Fibres - collagen
Ground Substance- fills spaces between cells
What are the 3 types of connective tissue and subtypes?
Proper - loose & dense
Fluid - Blood & Lymph
Supporting - Cartilage & bone
List some Supporting cells?
Fibroblasts, Chondrocytes, Osteocytes, Adipocytes
What are the 3 Fibre C Tissues?
Collagen - long, straight, flexible
Reticular - thinner, framework
Elastic - branched, wavy
Describe the Embryonic Classification of C tissue?
Migrates and interacts with other tissues to form organs from mesnchyme
i.e Umbilical cord
Describe the C tissue Proper Classification?
Fibroblast cells - spindle shaped
produces collagen
loose matrix
Describe Loose Proper C tissue?
Binding and packing - flexible- skin to underlying muscle
Describe Dense Regular C tissue?
Dense packed collagen fibres parallel to action i.e tendons
Describe Dense Irregular C tissue?
Dense packed collagen fibres, interwoven i.e dermis of skin
Describe Elastic C Tissue?
Elastic fibres- stretchy - walls of arteries
Describe Reticular tissue?
Network reticular fibres woven - jellylike - forms framework of organs
Describe Adipose tissue?
Cells store fat droplets - food reserve i.e surface of heart
Describe Cartilage?
Chondrocyte cell, semisolid matrix with elastic properties, supportive and protective, avascular, 3 types
What are the 3 Types of Cartilage?
Hyaline - stiff flexible support
Elastic- Support but tolerates distortion ie ear
Fibrocartilage - resists compressions i.e knee
Describe Bone classification?
Osteoblasts, Osteoclasts and Osteocyte cells
rigid due to calcium
rich vascular supply
Compact or cancellous
Describe Vascular Classification?
Erythrocytes, Leukocytes and Thrombocyte cells
viscous
liquid plasma
