06 Development of Body Cavity

chapter 4.1

A serous membrane is an epithelial membrane composed of mesodermally derived epithelium called the mesothelium that is supported by connective tissue. These membranes line the coelomic cavities of the body, that is, those cavities that do not open to the outside, and they cover the organs located within those cavities. They are essentially membranous bags, with mesothelium lining the inside and connective tissue on the outside. Serous fluid secreted by the cells of the thin squamous mesothelium lubricates the membrane and reduces abrasion and friction between organs. Serous membranes are identified according locations. Three serous membranes line the thoracic cavity; the two pleura that cover the lungs and the pericardium that covers the heart. A fourth, the peritoneum, is the serous membrane in the abdominal cavity that covers abdominal organs and forms double sheets of mesenteries that suspend many of the digestive organs.

scientist spotlight Dr Sun

 I have really love the scientist spotlight  reading about scientist how they achieve their academic goal .
Reading about their biography I have gain more courage. Dr Sun sacrifices, and struggle a lot although a lot of failures in research but she never gave up in her study. I am really impressed Dr.Sun She also one of the immigrant scientist  who had a hard time with language but I can able to achieve her goal and participated in writing  the paper Anti-Aging Potentials of Methylene Blue for Human Skin Longevity, which appeared in the prestigious journal, Nature, and received much attention in the press.
