What are the features of a simple squamous epithelium?
One layer of cells, very thin.. good for diffusion. Found in the alveoli
What are the features of cuboidal epithelium?
tubular in shape.. ring of cells. Found in the kidneys
What are the features of simple columnar epithelium?
Longer, thin, vertical cells. Found in the intestines
what are the features of stratified squamous epithelium?
layers of cells which can erode down. Refill upwards. Found in the mouth
What are the features of the pseudostratified columnar epithelium?
Appear long and thin like simple columnar epithelium, have villi. Found in the trachea.
What is the occluding junction?
Hold the cells together, tight junctions and anchoring junctions
What are communicating junctions?
Gap junctions, allowing for molecules to pass from one cell to the other
Explain the basal and apical side of a polar epithelia
B - Closely interacting with other cells
a - exposed to the lumen
What is Collagen
strong, non-elastic
What is elastic
made of elastin
What is reticular ?
Thin and highly branched, reticular fibres serve to join connective tissue to adjacent tissues
skeletal muscle makeup
muscle -> fibres -> myofibrils -> sarcomeres -> protein filaments -> actin(thin) / myosin (thick)
