| Name this Epithelium:
Typical Locations: Largest ducts of exocrine glands, anorectal junction.
Major Function: barrier, conduit | Stratified Columnar Epithelium
(very rare w/ visible goblet cells) |
| Name this Epithelium:
Typical Locations: Trachea and bronchial tree, ductus deferens, efferent ductules of epididymis
Major Function: secretion, conduit, absorption, conduit | Pseudostratified Epithelia
(** special: Nuclei are present at diff heights. Goblet cells intermingle w/ ciliated cells. All cells contact basement membrane) |
| In this type of epithelium, cells are both long and short, nuclei are present at diff heights, goblet cells intermingle w/ ciliated lining cells, and all of the cells contact the basement membrane | Pseudostratified Ciliated Columnar Epithelium |
| This epithelial tissue covers and lines internal organs. It also has "fried egg" appearance when viewed w/ a micrograph. | Simple squamous epithelium |
| Name this Epithelium:
Typical Locations: Epidermis (keratinized), oral cavity and esophagus (non-keratinized), vagina.
Major Function: Barrier and protection | Stratified Squamous Epithelia
(non-keratinized surface cells are still living) |
| Name this Epithelium:
Typical Locations: small ducts and glands, surface of ovary, kidney tubules, and thyroid follicles.
Major Function: absorption, conduit, barrier, absorption, secretion | Simple Cuboidal Epithelia (Note: think "ducts and glands". Looks diff than SSE b/c typically has open spaces of gland b/w cells. |
| Name this Epithelium:
Typical Locations: small intestine and colon, stomach lining and gastric glands, gallbladder.
Major Function: absorption and secretion | Simple Columnar Epithelia |
| Epithelia can be names by the number of cell layers.
______ - a single cell layer
______ - two or more layers | Simple
Stratified |
| The epithelium that rests on the loose connective tissue of the lamina propria and is formed by long cells with elliptical nuclei is ____? | Simple Columnar Epithelium |
| All blood vessels are lined with a simple squamous epithelium called _____? | Endothelium |
| The simple squamous epithelium that covers the body cavities is called ______? | Mesothelium |
| Epithelia can be names by the shape of the cells.
_____ - flat cells
_____ - cube-shaped cells
_____ - rectangular cells | Squamous
Cuboidal
Columnar |
| Some epithelial cells lack a free surface and are called _____ tissues. | Epitheloid |
| Name this Epithelium:
Typical Locations: vascular system (endothelium), body cavities (mesothelium), bowman's capsule (kindey), respiratory spaces in lung (alveoli).
Major Function: exchange, barrier in CNS, lubrication. | Simple Squamous Epithelia
("fried egg shaped) |
| Epithelium is an _____ tissue that covers the body surfaces, lines body cavities, and forms the secretory portions of glands. The basal surface of epithelium is attached to a _____ _____. | Avascular
Basement Membrane
(epithelium created a selective barrier b/w the external environment and the underlying connective tissue). |
| Name this Epithelium:
Typical Locations: renal calyces, ureters, bladder, urethra.
Major Function: barrier, distensible property. | Transitional Epithelium
(urothelium(Urinary Systems)) |
| This epithelium is specialized to stretch. | Transitional Epithelium |
| Secretion is an epithelial function that is found in the _____ epithelial of the stomach and the ____ glands. | Columnar Epithelium
Gastric Glands |
| Absorption is an epithelial function that can be found in the _____ epithelium of hte intestines and _____ epithelium of the _____ ______ tubules of the kidney. | Columnar Epithelium
Cuboidal Epithelium
Proximal Convoluted |
| The transport of materials or cells along the surface of an epithelium occurs by what? | Cilia |
| Protection is an epithelial function that occurs with the ____ ____ epithelium of the skin (epidermis). | Stratified Squamous Epithelium |
| To receive and transduce external stimuli, aka _____ function, is accomplished by the _____ ______ of the tongue, the ______ epithelium of the nasal mucosa, and hte ______ of the eye. | Receptor (function)
Taste Buds
Olfactory
Retina |
| Epithelia involved in secretion or absorption are usually ______, or in some cases, ______. | Simple
Pseudostratified |
| The type of epithelia compatible with a high rate of transepithelial transport is _____ _____ epithelia. | Simple Squamous |
| Stratification of epithelium usually correlates with _____ ______. | Transepithelial Impermeability |
| Some pseudostratified epithelia have _____ _____ cells that give rise to mature functional cells of the epithelium; a process that balances cell turnover. | Basal Stem Cells |
| Lateral derivatives of ______ are the serous membranes of pleura, pericardium, and peritoneum | Mesoderm |
| Epithelium of the trachea, bronchi, lungs, GI tract, liver, pancreas, urachus, pharynx, thyroid gland, tympanic cavity, pharyngotympanic tube, tonsils, and parathyroid gland all arise from what germ layer? | Endoderm |
| The 3 domains of epithelial cell polarity are the _____ domain or pole, the ____ domain or pole, and the _____ domain. | Apical Domain (faces a space)
Basal Domain (faces conn. tissue)
Lateral Domain (surface opposing another cell) |
