ET PT 2 Flashcards
Squamous (Ex. of distribution)
: Lining of vessels (endothelium); serous lining of cavities: pericardium, pleura, peritoneum (mesothelium)
Simple (one layer of cells)
Squamous, cuboidal, columnar
Simple: Main function of squamous
Facilitates the movement of the viscera (mesothelium), active transport by pinocytosis (mesothelium and endothelium) secretion of biologically active molecules (mesothelium)
Simple: Cuboidal ex. of distribution
Covering the ovary, thyroid
Simple: columnar ex. of distribution
lining of intestine, gallbladder
Simple: Main function of cuboidal
covering, secretion
Simple: main function of columnar
: protection, lubrication, absorption, secretion
Stratified (two or more layers of cells)
Squamous keratinized (dry), Squamous nonkeratinized (moist), Cuboidal, transitional, columnar
Squamous keratinzed (dry) ex. of distribution
epidermis
Squamous nonkeratinized (moist) ex. of distribution
Mouth, esophagus, larynx, vagina, anal
canal
Stratified: Cuboidal ex. of dist.
Sweat glands, developing ovarian follicles
Stratified: Transitional ex. of dist.
bladder, ureters, renal calyces
Stratified: Columnar ex. dist
conjunctiva
Squamous keratinzed (dry) MF:
protection, prevents water loss
Squamous nonkeratinized (moist) MF:
protection, secretion, prevents water loss
stratified: Cuboidal MF:
protection, secretion
Stratified: Cuboidal MF:
protection, secretion
Stratified: Transitional MF:
protection, distensibility
stratified: Columnar MF:
protection
Pseudostratified Ex. of dist
lining of trachea, bronchi, nasal cavity
Pseudostratified MF:
protection, secretion; cilia-mediated transport of particles trapped in mucus out of the air passages
Features: Elongated secretory portion; duct usually short or absent
Ex. Mucous glands of colon; intestinal glands or crypts (of Lieberkuhn)
Simple tubular
Features: Several long secretory parts joining to drain into 1 duct
Ex. Glands in the uterus and stomach
Branched tubular
Features: Secretory portion is very long and coiled
Ex. Sweat glands
Coiled tubular
Features: Rounded, saclike secretory portion
Ex. small mucuous glands along the urethra
Acinar/ alveolar
Features: Multiple saclike secretory parts entering the same duct
Ex. Sebaceous glands of the skin
Branched Acinar
Features: Several elongated coiled secretory units and their ducts converge to from larger ducts
Ex. submucosal mucous glands (of Brunner) in the duodenum
Tubular
Features: Several saclike secretory units with small ducts converge at a larger duct
Ex. Exocrine pancreas
Acinar(alveolar)
Features: Ducts of both tubular and acinar secretory units converge at larger ducts
Ex. Salivary glands
Tubuloacinar
