Stomach Pyloric Antrum Portion 

Mucous Gastric – smaller increase

1- Mucous Layer – Glandular Epithelial Tissue – Tubulosa Gland Branched Simple

2- Muscularis Mucosa Layer

3- Submucosa Layer

4- Muscular itself Layer

Mucous Gastric – Middle increase

1- Mucous Layer – Glandular Epithelial Tissue – Tubulosa Gland Branched Simple

2- Muscularis Mucosa Layer

3- Submucosa Layer

4- Muscular itself Layer

Arrow – (Tubules Coating) – Epithelial tissue with Simple Cylindric Coating

Star – Secretor Gland Portion

Red Triangle – Tubules

There are Gastric Pits

 

Gastric Mucosa – greater increase

Arrow- Epithelial Tissue with Simple Cylindric Coating

There are Gastric Pits

Body and Fundus Portion of the Stomach 

Gastric Mucous – smaller increase

Glandular Epithelial Tissue – Tubulosa Gland Branched Simple

*Component Cells of the Fundic Stomach:

-Parietal Cell – it can color itself with eosin and it has spherical core in central position. These cells are involved in the elaboration of hydrochloric acid and intrinsic factor.

-Chief (zymogen) Cell – it is smaller than parietal cell, cylinder, basophilic, and it has a round nucleus. It is involved in protein synthesis and secretion (pepsin, rennin and gastric lipase).

-Mucosa Cell – its cytoplasm can’t be colored in this technique. It secretes mucus.

-Endocrine Cells or Argentafin – it can be colored by the silver and it secretes hormones.

Gastric Mucous – greater increase
