Looks like a sunny-side up egg
Lines the esophagus and covers the skin
Squamous skin cancer is very common; due to excessive sun exposure
Polygonal cells have irregularly, angular shapes.
Most have 4 sides

Typically polygonal nerve cells that have extensions that give them a star-like appearance.
Cuboidal cells are squarish
They are as tall as they are wide
Like ice cubes
Columnar cells are markedly taller than they are wide.
They look like tubes
Most columnar cells line the intestines
Many intestinal cancers arise from columnar cells.
Sphere/Ovoid Shape Cells
Sphere are round shaped cells
Egg cells are sphere in shape
Ovoid are oval shaped cells
Fat cells can be both sphere or ovoid shaped
Discoid Shape Cells
Discoid shaped cells are like a disc with a small indentation in the center.
Red blood cells
Fusiform Shaped Cells
Fusiform shape is thick in the middle, long, with tapered ends.
It is similar to a parasitic worm shape.
Smooth muscles have these due to their stretching capability
Fibrous Shaped Cells
Fibrous shaped cells are like fibers
They are found in skeletal muscles
They have great stretching and mobility capability
Most human cells range from 10-15 um
The human egg cell is exceptionally large at 100 um
The longest human cell is the nerve cell
