Histology Block 1 Flashcards
3 functions of epithelial tissue
- covers body surfaces
- forms glandular tissue
- forms the tissue of receptors for the 5 senses
the 3 characteristics of any epithelium tissue
typical function of simple squamous epithelium
exchange, lubrication, barrier
simple cuboidal epithelium
what tissue type is shown
stratified squamous cell epithelium
what epithelial cell type(s) is shown (arrow)
Pseudostratified columnarepithelium appears to be stratified because the nuclei of the epithelial cells are at different levels. However, every cell is in contact with the basement membrane, but not all cells reach the lumen.
what epithelial cell type(s) is shown
karatinized stratified squamous epithelium
what epithelial tissue type is shown (arrow)
stratified squamous
what epithelial cell type(s) is shown (arrow)
simple cuboidal
(found in kidney and overy gland)
what epithelial cell type(s) is shown (arrows)
stratified cuboidal
what specific structures are being pointed to within the pseudostratified columnar epithelium
cells are closely packed together and adhere to one another laterally using ______ __________
junctional complexes
desmosome versus zonula adherens
name each junction type in the lateral domain
(from top to bottom):
- right junctions aka zona occludens
- Zona adherens
- desmosomes (aka macula adherens)
what type of cell junction is found on the basement membrane?
hemidesmosome
junctional complex includes:
tight junction and zona adherens
the zona adherens contains _______ on either side of the junction, wherease the desmosomes contain ___________on either side of the junction
- actin
- intermediate filaments
mitochondria
*the star represents the golgi complex NOT the SER
