|---|---|
| What is simple squamous epithelium? | a single layer of flat cells in contact with the basal lamina (basement membrane) of the epithelium. |
| Locations of the simple squamous epithelium are? | Alveoli of the lungs, Endothelium, Mesothelium(serous membranes), Nephrons(kidney tubules), Glomerulus(capillary), Bowman's Capsule, Loop of Henle |
| What does serous membranes have? | Peritoneum, Mesentery, Pleura, Pericardium |
| Functions of simple squamous epithelium in Alveoli and blood vessels //Nephrons // Serous membrane | exchange of gases, nutrients and waste products// Filtration // Lubrication |
| Simple cubodial epithelium locations? | Nephrons, ducts and follicles of glands |
| Functions of simple cubodial epithelium? | Kidney: reabsortion, secretion Thyroid Gland: synthesis and secretion of glandular product |
| Simple columnar epithelium locations? | Nephron and digestive tract |
| Simple columnar epithelium funcitons? | Secretion and absorption |
| Simple columnar ciliated epithelium location? | Digestive tract |
| Pseudostratified columnar ciliated epithelium location? | In Bronchi and Trachea |
| Stratified squamous epithelium has two types? | Nonkeratinezed and keratinized |
| Locations of Nonkeratinized stratified squamous epithelium | Mouth, pharynx, esophagus, anus, vagina |
| Location of keratinized stratified squamous epithelium? | Epidermis(top layer of skin) |
| Transitional epithelium characteristics? | Puffy bloated surface cells, usually 2 nuclei per surface cell, and usually a hard to see basement membrane |
| Locations of transitional epithelium? | Ureter, urinary bladder, urethra |
| Connective tissue-1)Loose A)areolar connective tissue locations? | Subcutaneous tissue, and in tissue sections almost every part of the body. (wikipedia) |
| B)Adipose locations? | Subcutaneous tissue, around the kidneys and heart, behind the eyeball, padding around joints, breasts of mature females |
