👉 The term "subvertebrate" is a medical term used to describe any part of the body that is not directly attached to the vertebral column, such as the spine or pelvis. It typically refers to the lower extremities (legs) and some parts of the upper body (arms, hips, shoulders). In general, subvertebrates are often associated with muscles, tendons, ligaments, and bones that support the skeletal structure of the body.
