Connective tissue Flashcards
(15 cards)
Pathologies related to connective tissue
Non-organ specific autoimmune diseases
Systemic lupus erythematosus
Rheumatoid disease
Mixed connective tissue disorders: Progressive systemic sclerosis, Polymyositis and dermatomyositis
Tumours
Fibroma, osteoma, chondroma, lipoma
What are consstituents of connective tissue
Cells, Matrix and Proteins
Examples of cells
Fibroblasts, macrophages, adipocytes
Examples of proteins
collagen, elastic and recticular
Examples of Matrix
Water and solutes
Connective tissue can be divided into 3 things
1) Fluid- blood and Lymph
2) Support - Bone and cartilange
3- Proper which is subdivided into loose and dense
Components of loose connective tissue
Areolar
Adipose
Recticular
Components of dense connective tissue
Regular
Irregular
Elastic
What is the extracellular matrix of connective tissue made of
Protein fibres like collagen and elastin
determines the physical properties of each type of connective tissue- different in each type of connective tissue
Functions of connective tissue
Metabolic and Physical Support to Epithelial Tissue
Supporting frameword
Carry blood vessels
Mediated exchange of metabolites
Storage
Function of aerolar
Acts as a “binding web”: connects different tissues and holds organs in place
Provides physical support, flexibility, and metabolic exchange (due to vascularity)
Found in umbilical cord
Provides cushioning and protection for umbilical blood vessels
Adipose tissue function
2 types; white and brown
energy, insulation and cushioning
Recticular tissue
Contain recticular fibres which are made up of collagen 3
Found in liver, kidney and spleen
Function- supports lymphoid organs
Location of dense irregular, regular and elastic connective tissue
Irregular - Dermis of Skin, Leather
Regular- Ligaments (connect bones to bones) and tendons (muscle to bone)
Elastic - Ear
What are connective tissues derived from
Primitive mesenchyme (embryonic connective tissue)
