Mesothelium
Mesothelium is simple squamous epithelium derived from the middle embryonic germ layer known as the mesoderm. It is sometimes called pavement epithelium as the cells are analogous to flat tiles on a floor. Credit: Ed Reschke/Photolibrary/Getty Images

Definition:

The prefix (meso-) comes from the Greek mesos or middle. (Meso-) means middle, between or intermediate.

Mesoglea (meso-glea) - layer of gelatinous material located between outer and inner cell layers in some invertebrates including jellyfish and hydra.

Mesonephros (meso-nephros) - the middle portion of the embryoinc kidney.

Mesomere (meso-mere) - a blastomere (cell resulting from the cell division or cleavage process that occurs following fertilization) of medium size.

Mesomorph (meso-morph) - individual with a muscular body type predominated by tissue derived from the mesoderm.

Mesophyll (meso-phyll) - photosynthetic tissue of a leaf, located between the upper and lower plant epidermis.

Mesosome (meso-some) - anterior portion of abdomen in arachnids located between the cephalothorax and lower abdomen.

Mesosphere (meso-sphere) - Earth's atmospheric layer located between the stratosphere and thermosphere.

Mesothelium (meso-thelium) - epithelium that is derived from the mesoderm embryonic layer.

It forms simple squamous epithelium.
