Epithelial Tissue Flashcards
Major type of collagen of basal lamina
Type 4
Protein that maintains barrier between adjacent cells
Occludin
Regulate mechanism of growth and cell diffrentiation
Cadherin
Forms the primary intercellular diffusion barrier between adjacent cells
Zonula occludens
Proteins that form extracellular aqueous channel
Claudin
Staining technique to identify basement membrane
Periodic acid schiff
Type of cilia found on eukaryotic cells which serves as chemosensors
Primary cilia
It is a sheet like arrangement of extracellular matrix
Basement membrane
Anchoring fibril that links the basal lamina to the reticular lamina
Type 7
Pathway that occurs across the zonula occuludens between two epithelial cells
Paracellular pathway
Part of cam families expressed on white blood cells
Selectins
Cilia numerous on apical domain of epithelial cells
Motile cilia
It is a major cell to cell junction that provides a strong attachment
Macula adherens
Collagen that stabilizes external lamina in skeletal and cardiac muscle
Type 15 collagen
Pathway across the plasma membrane of the epithelial cell
Transcellular pathway
Cam family protein that interacts with extracellular matrix and with actin and intermediate filaments
Integrin
It is a cytoplasmic process that contains a core of actin filament
Microvilli
The height of the cell exceed width
Columnar cell
Control epithelial growth and differentiation
Basement membrane
Shape of Excretory ducts of sweat glands and salivary glands
Stratified cuboidal epithelium
It is an impermeable junction
Occluding junction
It is found in bilaminar embryonic disc of the embryo during gastrulation
Nodal cilia
Lines the urinary bladder, ureter, and upper urethra
Transitional epithelium or urothelium
Collar like extension between the transitional zone of basal body and plasma membrane
Alar sheet
It is a movement of moving mucus ober epithelial surfaces
Cilia metachronal rhythm
Protein involve in cell to extracellular matrix interaction
Laminin
Junctions that provides mechanical stability to epithelial cells
Anchoring junction or adhering
Cytoplasmic process containing bundles of microtubule
Cilia
From tip of the cilium to its base
9+2 Microtubules array
Link between laminin and type 4 collagen
Entactin or nidogen
Cell junction capable of cell to cell recognition due to its signal transduction
Anchoring junction
Conjuctiva lining of the eyelids
Stratified columnar epithelium
Communicates with adjacent cells and is characterized by specialized attachment areas
Lateral domain
Mediate homotypic cell to cell ashesion
Immunoglobulin super family
Mediate cell to cell contact providing anchoring sites for intermediate filaments
Macula adherens
Anchors the intermediate filament to the cytoskeleton into the basement membrane
Hemidesmosomes
Nuclei lie at different level but attached to basement membrane
Pseudostratified columnar epithelium
Protein responsible for the formation of occluding junctions in the endothelial cells and monocyte
Junctional adhesion molecules
Controls and regulates diverse intracellular processes
Cell adhesion molecules
Amino acid sequence of the cytoplasmic portion pf the 3 proteins of zonula occludens
PDZ domain proteins
Found in the mid region of the basal body
Basal foot
Has a core of about 20-30 actin filament
Microvilli
Where can you find stereo cilia?
Epididymis, ductus deferens, sensory hair cels of inner ear
It is found in the lining of vagina, esophagus and mouth
Stratified non keratinized epithelium
It is supported by internal bundles of actin filaments cross linked by fimbrin
Stereovilli
Provides direct passage of signaling molecules from one cell to another
Gap junction
Junction for epithelial surface integrity
Zonula adherens
