Anatomy and physiology course question.?

Question

Mesenteries: which consist of two layers of peritoneum fused together, connect the visceral peritoneum of some abdominopelvic organs to the parietal peritoneum on the body wall or to the visceral peritoneum of other abdominopelvic organs.

Can someone please explain what is said in this definition above. I am so confused.

Answer 1

this is a way layman's answer but basically it is the stuff that keeps your organs in place. if it werent there they would move all the time and possibly get twisted around each other etc......so its sorta like a spiderweb holding the wall of the organ to the wall of your skin......make any more sense?

Answer 2

I am an MD. This is just semantics, really, i.e. a way to speak and describe the anatomy. Remember that intestines are living things, and as such, they require food and oxygen in order to stay alive. Like most organs in the body, they receive this food and oxygen from the blood, coming through blood vessels. These blood vessels come off the Aorta as the superior mesenteric artery and the inferior mesenteric artery. They split up into multiple arches, called arcades, sending yet smaller arteries off of these to the intestines themselves. I think of it like a Roman aquaduct, with the water channel on the top being the intestine, with the multiply repetitive blood vessel arches directly below, being the mesentery. Now imagine the whole thing covered in saran wrap, which is otherwise called the peritoneal membrane, and then spreading out across the ground. The part of the saran wrap that is up covering the aquaduct itself and its supporting arches is the "visceral peritoneum" and the part of the saran wrap that is lying flat on the ground surrounding the aquaduct is the "parietal peritoneum". This really is how your body is set up. I hope this helps.

Answer 3

Most colleges or university's have anatomy and psysiology. But you need labs, so on-line will not work. I had to have them for my degree. Look for a technical college, and go to the class.

Answer 4

Ever seen the membranes that connect the coils of the small intestines? Those are examples of mesenteries.
