0 a smooth membrane that lines body cavities and keeps them moist: --
The oesophagus has no serosa, thus reducing the resistance against local spread of invasive cancer cells.
This is because inside the maternal chorion two additional membranes develop from embryonic tissue, the amnion and the serosa.
This is because inside the chorion two additional membranes develop from embryonic tissue, the amnion and the serosa.
Each serosa is made up of a single layer of squamous epithelial tissue as mesothelium which produces the serous fluid.
The space between the amnion and the serosa constitutes the extra-embryonic celom, and for a time communicates with the embryonic celom.
The cancer usually first spreads into the myometrium and the serosa, then into other reproductive and pelvic structures.
To some degree, its role is complementary to that of the serosa, which also provides a layer of tissue surrounding an organ.
The esophagus also has an adventitia, but not a serosa.
Underneath the epithelia is an underlying lamina propria, muscularis, perimuscular layer and serosa.
