Histology (connective tissue)


Bismillahirahmanirrahim

Summarization on study of Connective Tissue

Okay, basically, connective tissue can be divided into 2 types :

1. Proper
-Loose 
(remember the picture with clearly seen elastic fibre (brown) and collagen fibre (pink thick)
-Dense
(*picture irregular dense CT in dermis of the skin- the elastic fibre is thick pink, different with loose CT)
-Adipose

2.Specialized
-Cartilage
-Bone 
-Blood


Then, the main component of connective tissue is also 2 :

1. Connective tissue 'cell' :

Divide into 2 :

* Fixed cell;
(FAPMM)
-Fibroblast
-Adipocyte
-Pericyte
-Mast cell
-Macrophages

*Wandering/free cell :
(Pergi Lari Nak, Belikan  Mama Maggi)
-Plasma cells
-Lymphocyte
-Neutrophils
-Basophils
-Monocyte
-Macrophages

2. Extracellular matrix of connective tissue :-
Got 2 division also :

1. Ground subtstance that amourphous gel like material, they are :
-Glycosaminoglycan
-Proteoglycan
-Glycoprotein

Then, fibres :
-Collagen
-Reticular
-Elastic

Besides, connective tissue also classified based on those features (Classification)  :

1. Dense CT (Irregular/Regular)- but basically, the irregular one found in the dermis of skin.
2. Reticular connective tissue
3. Adipose CT
4. Loose CT

Okay.. in simple view :) Hope I can remember it later :D In shaa Allah :)
