What term describes the navel?

The term that specifically describes the navel is "umbilicus." This term is derived from Latin, where "umbilicus" refers to the central point of attachment for the umbilical cord during fetal development. The umbilicus is a notable anatomical feature as it marks the spot where the umbilical cord connected the developing fetus to the placenta, providing essential nutrients and oxygen.

In contrast, submental refers to the area beneath the chin, costal margin pertains to the lower edge of the rib cage, and pectoral girdle refers to the structure that supports the upper limbs and connects them to the torso. None of these terms relate specifically to the navel, highlighting the specificity of "umbilicus" in this context. Understanding these anatomical terms is crucial for accurate communication in medical and forensic fields, specifically in the context of death investigation where precise language is vital.
