GLANDS
- GLANDS
- based on number of cells
- unicellular
- multicellular
- based on presence of duct
- exocrine
- number of branches of duct
- simple
- crypts of leiburkuhn
- sweat glands
- fundic glands of stomach
- mucous glands of urethra
- meibomian glands
- compound
- Brunner's glands
- mammary glands
- submandibular glands
- shape of secretory unit
- tubular
- coiled
- sweat glands ( coiled tubular)
- Intestinal glands
- gastric glands
- acinar
- exocrine pancreas
- salivary glands
- alveolar
- nature of secretory product
- serous
- serous acini
- lined by pyramidal shaped simple columnar epithelium
- rounded basal nucleus
- Rough endoplasmic reticulum
- basal basophilia
- golgi complex well developed
- apical eosinophilia
- lumen
- smaller than mucous acini
- examples
- mucous
- mucous acini
- lined by pyramidal shaped simple columnar epithelium
- flat elongated basal placed nucleus
- empty cytoplasm on H&E staining
- mucus stored in form of mucinogen granules
- lost during preparation of tissue specimen
- lumen
- wider
- staining
- positive with periodic-acid-schiff staining
- dark magenta stain
- mixed
- mucous acini with serous demilunes
- endocrine
- based on manner of secretion
