Enteroscopy is also known as a: double balloon enteroscopy; double bubble; capsule enteroscopy; push-and-pull enteroscopy; The two types of enteroscopy are upper and lower. In an upper enteroscopy, the endoscope is inserted into the mouth. In a lower enteroscopy, the endoscope is inserted into the rectum. The type of enteroscopy performed will depend on the type of problem the doctor is trying to diagnose.
For other uses, see Sacrum (disambiguation). The sacrum (/ËsÃ¦krÉm/ or /ËseÉªkrÉm/; plural: sacra or sacrums; Latin os sacrum) in human anatomy is a large, triangular bone at the base of the spine, that forms by the fusing of sacral vertebrae S1âS5, between 18 and 30 years of age. The sacrum articulates (forms a joint) with four other bones.
However, during normal development several vertebrae fuse together, leaving a total of 24, in most cases. The confusion about whether or not there are 32-34 vertebrae stems from the fact that the two lowest vertebrae, the sacrum and the coccyx, are single bones made up of several smaller bones which have fused together. This is how the vertebrae are counted: 24 separate vertebrae and the sacrum, formed from 5 fused vertebrae and the coccyx, formed from 3-5 fused vertebrae.
