Histology Flashcards
What are the four categories of tissues
Epithelial tissue
Connective tissue
Muscular tissue
Nervous tissue
What stain do we use
H&E stain
Epithelium has specialised functions of
Barrier internal/ external environment
Mechanical protection
Absorption and secretion
What do cell-cell junctional complexes do
Function to link cells together but can also have functional implications
Surface epithelia are classified using 3 criteria of
Number of cell layer
Shape of surface cells
Surface specialisations
All cells rest on what
Basement membrane
Simple squamous epithelium
Functionally suited to surfaces where mechanical protection is not required
Blood vessels
Simple cuboidal epithelium
Suited to surface with absorption role
Simple columnar epithelium
Suited to surfaces with an absorptive role
Keratinised statified squamous
High degree of mechanical protection eg. Foot pad
Transitional or urothelium
Required to stretch eg. Urinary bladder
Goblet cells
Single cells that retain connection with surface epithelial cells
Glandular epithelium with a duct to the surface has what gland
Exocrine gland
Glandular epithelium without a duct has what gland
Endocrine
Serous secretory has what colour stain
Dark
