What is the width and length of human colon?

The main job of the colon is the reabsorption of water and salts from chyme that enters into it from the small intestine. As the water is drawn out it turns into feces. For this reason it has to be wider than the small intestine, which is about an inch in diameter. On average the colon is about four feet long and two inches wide in most places. Some parts, like the cecum, can be wider, up to three inches, while other places, like the anal canal, can be a bit narrower if it is empty. The colon is also known as the large intestine. It is divided into four segments, totaling approximately 60 inches on average. 1) The Ascending colon connects to the small intestine, and is about 8 inches long. 2) The Transverse colon is usually over 18 inches long and extends from the hepatic flexure, across the upper abdomen to the splenic flexure. 3) The Descending colon is usually less than 12 inches long and extends from the splenic flexure downwards to the start of the pelvis. 4) The Sigmoid colon is S-shaped and is about 18 inches long. It extends from the descending colon to the rectum. The rectum measures from 4-6 inches in length.

What is a neural tube?

The neural tube is the part of the development of the central nervous system in a developing embryo. What is pretty amazing about this is that within the first 4 weeks of development from conception, the entire framework of the central nervous system will have finished forming! Around day 18, the neural plate appears at the midline of the thickening of the ectoderm, the outermost layer of the germinal sac. Essentially what happens over the next couple of days is that the neural plate forms a depression, which eventually is pushed down and separated from the original cell layer by the fusion of the neural crests, resulting in the formation of a neural tube - this is rather hard to explain without a proper diagram!
