How Do You Spell ANNULUS UMBILICALIS?

1. Annulus umbilicalis is a term used in anatomy and medicine to refer to a circular fibrous band that surrounds or encircles the umbilicus, commonly known as the belly button. Derived from the Latin words "annulus" meaning ring or circle, and "umbilicalis" referring to the umbilicus, this structure is primarily composed of connective tissue fibers.

   The annulus umbilicalis plays a crucial role in the embryonic development of mammals. During the prenatal period, this structure helps to secure the blood vessels that connect the fetus to the placenta, enabling the exchange of oxygen, nutrients, and waste products. Specifically, it serves to stabilize and protect the umbilical cord, which consists of blood vessels responsible for nourishing the developing fetus.

   As an individual matures, the annulus umbilicalis undergoes changes and gradually becomes less prominent. However, it often remains visible as a remnant or scar-like mark on the abdominal wall after the separation of the umbilical cord at birth. Additionally, it can serve as an anatomical landmark for certain surgical procedures, such as laparoscopy.

   Overall, the annulus umbilicalis is a structural component that is essential during fetal development and contributes to the formation and maintenance of the umbilicus. It serves as a connection point between the growing fetus and the placenta, playing a vital role in the transportation of essential substances for the baby's growth and development.

2. Umbilical ring, an opening in the linea alba through which pass the umbilical vessels in the fetus; it is at first near the pubis, but gradually ascends to the center of the abdomen; it is closed in the adult, its site being indicated by the umbilicus or navel.
