Parotid Salivary Gland

 
Parotid Salivary Gland HistologyIdentification Points: 

1. Serous acini (pyramid shaped secretory cells with round basal nucleus) 

2. No Serous Demilune

3. Striated Ducts

Description:

It is a large capsulated serous gland, subdivided into lobes and lobules by connective tissue septa located just anterior to the ears. It secretes 25% of total saliva which is serous (watery) in nature. At higher magnifications small secretory granules are visible in apices of serous acini

Fundus and Body constitutes most extensive region of Stomach. There are 4 general regions ( inside to outside ) : Mucosa (Epithelium + Lamina Propria + Muscularis Interna) Submucosa Muscularis Externa (Circular & Longitudinal Smooth Muscle layers) Serosa Important Labels ( Additional to above 4 ) Parietal Cells &  Chief Cells (Gastric Glands) Gastric Pits Oblique Muscle Layer (Characteristic Feature)

The histology of Intrapulmonary bronchi is similar to that of the trachea and extra-pulmonary bronchiole, except that C-shaped cartilage rings are absent here and replaced by cartilage plates. Intrapulmonary Bronchus :  Pseudo-stratified Columnar Ciliated Bronchial Epithelium Cartilage Plates & Seromucous Bronchial Glands Terminal Bronchiole :  Simple Columnar Epithelium  Prominent mucosal folds & well developed smooth muscles Respiratory Bronchiole :  Simple Cuboidal Epithelium  Alveolar Out-pocketings in the wall  Gives rise to alveolar ducts Alveolar Walls :  Out-pocketings of respiratory bronchioles type 1 & 2 Pneumocyets  Also contain Alveolar macrophages  Bands of Smooth muscle fibres in interalveolar septa
