Uterus (Follicular Phase)

Surface lining of Endometrium is Simple Columnar Epithelium, which extends downwards forming long, tubular Uterine Glands.

In Proliferative/Follicular Phase these glands are mainly straight in upper portion of endometrium and branch out in lower portion, because of which numerous glands are seen in cross section (in Basalis layer). 

During menstrual cycle, endometrium exhibit morphological changes that are correlated with ovarian functions. These cyclic changes are divided into 

  • Proliferative/follicular Phase
  • Secretory/luteal Phase
  • and Menstrual Phase

Important Labels:
  • Endometrium (Functionalis and Basalis Layers)
  • Myometrium (Smooth longitudinal & cross-sectional muscles)
  • Lining Epithelium
  • Uterine Glands
  • Spiral/Coiled Arteries

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
