Study Notes
Epithelial Tissue
- Artery: Small and regular lumen, thin wall.
- Vein: Large and irregular lumen, thin wall.
- Blood Vessel (Aorta): Contains simple squamous epithelium (endothelium). Also has a layer of flat epithelium.
Kidney (Renal Corpuscle)
- Place of filtration of blood: Simple squamous epithelium (Bowman's capsule).
- First Part of Nephrons: Covered by two membranes.
Peritoneum
- Peritoneum (Peritoneal membrane): Simple squamous epithelium (mesothelium).
Renal Tubules (Kidney)
- Renal tubules (kidney): Simple cuboidal epithelium.
Intestinal Villi (Intestine)
- Intestinal villi (Intestine): Simple columnar epithelium with oval nuclei. Finger-like projections important for absorption.
Trachea
- Trachea: Pseudostratified ciliated columnar epithelium (part of the respiratory system).
Esophagus
- Esophagus: Stratified squamous nonkeratinized epithelium.
Skin (Epidermis)
- Thick skin (Epidermis): Keratinized stratified squamous epithelium.
Urinary Bladder
- Urinary bladder (urinary tract except kidney): Transitional epithelium.
Intestinal Villi (Goblet cells)
- Intestinal villi: Goblet cells are unicellular glands.
Mammary Gland (Apocrine)
- Mammary Gland (Apocrine): Secretory units (acinus).
Skin (Sebaceous glands)
- Sebaceous glands (cluster): Simple branched acinar glands in the dermis.
Thyroid Gland
- Thyroid gland: Thyroid follicle, connective tissue, and blood vessel.
Pancreas
- Pancreas (exocrine): Pancreatic acini, glandular acini, acinus, alveoli, and alveolus. Secretion of enzymes.
Intestine (Intestinal Glands)
- Intestinal Glands: Goblet cells, cilia, lamina propria, and inflammatory cells.
Sweat Gland
- Sweat Gland: Ductal part of sweat gland, secretory part, and connective tissue.
Stomach (Gastric Glands)
