1. Connective tissue The cells; are two types
As the name implies ,connects and holds other tissue together .
Functions
Heat regulation ,storage, defense ,protection, and repair
Structure of connective tissue.
The connective tissue chiefly consisted from :
The Fibers; are three types:
Elastic fibers.
Collagen fibers.
Reticular fibers.
The cells; are two types
Fixed cells(fibroblast, fiberocytes, pericyte).
Transient (wandering) cells;(plasma cells, lymphocytes, mast cells, macrophage, leukocytes).
Amorphous ground substance;

2. Plasma cell ;large spherical –oval shape
with eccentric nucleolus (
Macrophage it is large oval in shape
&have Foamy cytoplasm
Fibroblast (elongated & spindle shaped with
long cytoplasmic processes & large oval
nucleus
Mast cells are large polymorphic contain numerous large met chromic granules (heparine,histamin&serotonin)

4. Mast cells are large polymorphic contain numerous large met chromic granules(heparine,histamin&serotonin)

5. Classification of connective tissue;
They are classified into 2 large groups:
A- Embryonic C.T.: this type involve
1. Mesenchymal C.T. ( limited in emberyon)
2.Gelatinous C.T.(mucous).(in embryonic hypo derma and umbilical cord)
B-Adult C.T. this type involved the following types.
Loose connective tissue:
It characterized by dominated of
transient cells than fibers,
This type found in most organs
such as (subcutaneous and
interstitial within organ system ,
muscle fibers and its sheaths and
a round bundles of peripheral
nerve fibers , adipose tissue and
blood vessels
