| Mesothelium | epithelium of body cavities
🗑

| Endothelium | epithelium of cardiovascular system
🗑

| Parenchyma | functional part of gland (made of epithelium)
🗑
|
||||
| Stroma | supportiv/structural part of gland (made of epithelium)
🗑
|

| 7 fxns of epithelium | protection, absorption, excretion, surface transport, digestion, lubrication, special (hair cells of ear; taste cells; ova, sperm)
🗑
|
||||
| types of epithelium | squamous, cuboidal, columnar, pseudostratified, transitional; keratinized or not
🗑
|
||||
| simple squamous attribute and example | rapid movement across epithelium; villi of lungs, capillaries
🗑
|
||||
| simple cuboidal attribute and example | ion pumps, secretory cells; kidney
🗑
|
||||
| simple columnar attribute and example | secretory or absorptive cells; small intestine
🗑
|
||||
| stratified squamous attribute and example | protection; 2 types-dry and wet; keratinized-epidermis; nonkeratinized-vagina, esophagus
🗑
|
||||
| stratified cuboidal attribute and example | rare; in ducts of sweat glands
🗑
|
||||
| stratified columnar attribute and example | rare; found at jxns between stratified squamous and simple columnar
🗑
|
||||
| pseudostratified attribute and example | all the cells have their basal on the basal membrane; trachea, bronchi, epididymis
🗑
|
||||
| transitional attribute and example | number and shape of layers appear to vary, depending on distention; urinary bladder
🗑
|
||||
| 4 modes of glandular secretion | merocrine (only secretory product is released); apocrine (small amounts of cytoplams are released as well), holocrine (entire cell is secreted), endocrine (secretory product is released in extracellular space rather than free epithelial surface)
🗑
|
||||
| carcinoma | cancer (neoplasm) of epithelial tissue
🗑
|
||||
| adenocarcinoma | cancer of glandular epithelial tissue
🗑
|
||||
| differences in carcinomas | increased mobility of cells, variable size of nuclei, nuclei intensely stained, cells less polarized, groups of cells less organized, cells lack intercellular jxns, move across basement membrane, and more obvious ones
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
