Connective tissues1. Classification

2. Loose connective tissue

a. cells

b. intercellular substance: fibers + ground substance

3. Dense connective tissue

4. Connective tissues with special properties:

a. Adipose tissue.

b. Reticular tissue

c. Mucous tissue

fibers ground substance

colagen, elastic, reticular

Connective tissues kinds of cells:

1. Fibroblastic cells (necessary cells): fibroblastes, fibrocytes, myofibroblastes, fibroclastes.

2. Migrated cells – from blood till connective tisues replaced: macrophages (from monocytes), plasma cells (from B-lymphocytes), mast cells (from basofills), lymphocytes, neutrofiles.

3. No necessary cells: adipocytes, pigmental cells, adventitial cells, pericytes.
