What anatomical term refers to the pelvis?

The anatomical term that refers to the pelvis is "pelv." This term is derived from the Latin word "pelvis," which means basin, reflecting the shape and function of the pelvic region in the body. The pelvis serves as a crucial structure that supports the trunk and houses various organs such as the bladder, reproductive organs, and part of the intestines. The prefix "pelv-" is commonly used in medical terminology, often found in terms related to pelvic health, anatomy, and various medical conditions associated with this area.

The other options represent different anatomical regions. The inguinal refers to the groin area, dorsal pertains to the back, and thoracic refers to the chest region. Each of these has distinct anatomical implications, which do not relate to the pelvis itself.
