Sagot :
Serosa and Mesocolon are the names of the individual mesenteries associated with specific gi organs.
Serous membrane (or serosa) is a smooth tissue membrane of mesothelium lining the contents and inner walls of body cavities, which secrete serous fluid to allow lubricated sliding movements between opposing surfaces. The serous membrane that covers internal organs is called a visceral membrane; while the one that covers the cavity wall is called the parietal membrane. Between the two opposing serosal surfaces is often a potential space, mostly empty except for the small amount of serous fluid. The fluid is produced by the serous membranes and stays between the two layers to reduce friction between the walls of the cavities and the internal organs when they move with respect to one another, such as when the lungs inflate or the heart beats. Such movement could otherwise lead to inflammation of the organs.
In the human body, there are four serous cavities with associated serous membranes:
- A serous membrane lines the pericardial cavity of the heart, and reflects back to cover the heart. Called the pericardium, this serous membrane is a two-layered sac that surrounds the entire heart except where blood vessels emerge on the heart’s superior side.
- The pleura is the serous membrane that surrounds the lungs in the pleural cavity;
- The peritoneum is the serous membrane that surrounds several organs in the abdominopelvic cavity.
- The tunica vaginalis is the serous membrane, which surrounds the male gonad, the testis.
Mesocolon is a single structure derived from the duodenojejunal flexure and extend to the distal mesorectal layer.
- The transverse mesocolon is that section of the mesocolon attached to the transverse colon that lies between the colic flexures.
- The sigmoid mesocolon is that region of the mesentery to which the sigmoid colon is attached at the gastrointestinal mesenteric margin.
- The mesoappendix is the portion of the mesocolon connecting the ileum to the appendix. It may extend to the tip of the appendix. It encloses the appendicular artery and vein, as well as lymphatic vessels, nerves, and often a lymph node.
- The mesorectum is that part attached to the upper third of the rectum.
