Structure and Function Flashcards
1
Q
Basal cell layer
A
Usually one cell thick
Small cuboidal
Lots of intermediate filaments (keratin)
Highly metabolically active
2
Q
Prickle cell layer
A
Larger polyhedral cells
Lots of desmosomes (connections)
Intermediate filaments connect to desmosomes
3
Q
KGPBD
A
Keratin layer Granular layer Prickle cell layer Basal layer Dermis
4
Q
Which layer would you find keratohylin granules (contain structural filaggrin & involucrin proteins) and odland bodies (lamellar bodies)?
A
Granular layer :)
think about it, they sound like granules!
5
Q
Origin of ‘cornified envelope’
A
Granular layer
6
Q
Cell nuclei are lost by this layer?
A
Granular layer
7
Q
Corneocytes: overlapping non-nucleated cell remnants Insoluble cornified envelope 80% keratin & filaggrin Lamellar granules release lipid Tight waterproof barrier
A
Keratin layer
8
Q
Which layer would you find corneocytes?
A
Keratin layer
