Four types of tissues
Epithelial, muscle, connective, neural
Epithelial tissue functions
Protection, permeability, movement of materials, secretory glands
Epithelial characteristics
Cellular, polar, regenerative, strong sensory, avascular
Place where epithelial cells sit
Basement membrane
Basement membrane functions
Physical support, anchor to connective tissue, provides polarity
Top side of cell on basement membrane
Apical
Side of cell sitting on basement membrane
Basal
What is the function of cell junctions?
Anchor cells together
cell junction that resists stress and is permeable
Desmosome
Cell junction that is impermeable and encircles the cell
Tight junction
Cell junction that forms tunnel to allow ions to travel between
Gap junction
Flat/thin cell
Squamous
Cube shaped cell
Cuboidal
Rectangular cell
Columnar
False layer cell
Pseudostratified
One layer of cells
Simple
Multiple layers of cells
Striated
Simple squamous function
Diffusion
Simple columnar function
Absorption and secretion
Simple cuboidal function
