The term "plica umbilicalis media" refers to a fold of tissue found in the umbilical cord. The spelling of this phrase can be explained through the use of the International Phonetic Alphabet (IPA), which assigns a specific symbol to each distinct sound in a word. The pronunciation of "plica" is /ˈplɪkə/, while "umbilicalis" is pronounced /ˌʌmbɪˈlaɪkəlɪs/ and "media" is pronounced /ˈmidiə/. The correct spelling of this term ensures accurate communication in medical contexts.
Plica umbilicalis media, also known as the median umbilical fold, is a term used in anatomy to describe a specific anatomical structure found in the human body. This fold is located within the region of the umbilicus or belly button, specifically on the inner surface of the anterior abdominal wall.
The plica umbilicalis media is a visible, longitudinal ridge that runs vertically from the umbilicus to the xiphoid process, which is the small bone at the lower part of the sternum or breastbone. It is a remnant of an embryonic structure known as the urachus, which is a tube-like structure that connects the bladder to the umbilicus during fetal development.
This umbilical fold is composed of fibrous tissue and varying amounts of fat, and its appearance can differ among individuals. In some cases, it may be visible and prominent, while in others it may be less pronounced or even absent. Its main function is to provide stability and support to the umbilical region.
The plica umbilicalis media is of clinical importance. During surgical procedures, such as abdominal exploration or laparoscopic surgery, it can serve as a useful landmark for identifying nearby structures. Overall, a thorough understanding of the plica umbilicalis media is vital in the study of human anatomy and for medical professionals involved in surgical interventions in the abdominal region.
Middle umbilical fold, p. urachi, a fold of peritoneum on the anterior wall of the abdomen covering the urachus, or remains of the allantois.
