Question | Answer |
what layer separates the epithelium from the underlying connective tissue? | basement membrane (basal lamina) |
basal lamina and connective tissue form what? | basement membrane |
basement membrane functions? | attachment, filtration, tissue compartmentalization, and confers cell polarity and shape |
is basement membrane vascular? | no |
stratified cells differ from simple cells how? | the stratified cells have multiple cells not attached to the basement membrane |
simple squamous that lines the vascular system is called what? | endothelium |
simple squamous that lines the body cavities is called what? | mesothelium |
what type of simple squamous lines respiratory spaces? | pneumocytes |
where are simple cuboidal cells located? | small ducts of exocrine glands and kidney tubules |
where are simple columnar cells located? | small intestine and colon, gallbladder, stomach and gastric glands |
pseudostratified ciliated columnar epithelium cells all attach where? | basement membrane |
pseudostratified ciliated columnar epithelium cells located where? always have what feature? | trachea and bronchi lining, lining of vas deferens, epididymis; always have cilia |
stratified cuboidal/stratified columnar are found where? | mammary, sweat glands, anorectal junction, and large ducts of exocrine glands |
stratified squamous is found where? | epidermis, lining of oral cavity/esophagus, lining of vagina (can be keratinized or non-keratinized) |
transitional cells found where? | renal calyces, bladder, urethra, ureter |
endocrine glands have ducts or not? | no |
unicellular glands are composed of a single cell; give an example: | goblet cells in tracheal epithelium |
multicellular glands have what 2 portions? | duct and secretory portions |
goblet cells secrete what? | mucus |
serous secretions consist of what? example? | watery secretions rich in enzymes; parotid |
mixed secretions make what two things? example? | mucus and serous; submandibular gland |

transformation of one cell type to another: | metaplasia |
is metaplasia reversible? | yes |
an abnormality in the appearance of cells indicative of an early step towardstransformation into a neoplasia: | dysplasia |
benign epithelial neoplasm that arises from surface epithelia? | polyp |
