From that point, pressure from the presenting part (head in vertex births or bottom in breech births), along with uterine contractions, will dilate the cervix to 10 centimeters, which is "complete." Cervical dilation is accompanied by effacement, the thinning of the cervix. General guidelines for cervical dilation: Latent phase: 0–3 centimeters
Megacolon is an abnormal dilation of the colon (also called the large intestine ). [ 1][ 2] This leads to hypertrophy of the colon. [ 2] The dilation is often accompanied by a paralysis of the peristaltic movements of the bowel. In more extreme cases, the feces consolidate into hard masses inside the colon, called fecalomas (literally, fecal ...
21–22. Right and left kidneys. The front border of the liver has been lifted up (brown arrow). [ 3] The bile duct[ 1][ 4] (formerly known as the common bile duct[ 4]) is a part of the biliary tract. [ 4] It is formed by the union of the common hepatic duct and cystic duct. It ends by uniting with the pancreatic duct to form the ...
The cervix is the lower part of the uterus situated between the external os (external orifice) and internal os (internal orifice). The cervical canal connects the interior of the vagina and the cavity of the body of uterus. The cervix is part of the female reproductive system.

Frequency. 0.09%. Aneurysm of the aortic sinus, also known as the sinus of Valsalva, is a rare abnormality of the aorta, the largest artery in the body. The aorta normally has three small pouches that sit directly above the aortic valve (the sinuses of Valsalva), and an aneurysm of one of these sinuses is a thin-walled swelling.
It is approximately 1.5 centimetres (5 ⁄ 8 inch) in diameter in newborns after 35 weeks of gestational age, [7] and 2.5–3 cm (1– 1 + 1 ⁄ 8 in) in diameter in adults. On abdominal X-rays , the small intestine is considered to be abnormally dilated when the diameter exceeds 3 cm. [ 8 ] [ 9 ] On CT scans , a diameter of over 2.5 cm is ...
Left atrial enlargement can be mild, moderate or severe depending on the extent of the underlying condition. Although other factors may contribute, left atrium size has been found to be a predictor of mortality due to both cardiovascular issues as well as all-cause mortality. Research suggests that left atrium size as measured by an echo ...
