Which term describes the back of an animal?

The correct term that describes the back of an animal is "dorsal." In anatomical terminology, "dorsal" refers specifically to the back side or upper surface of an animal's body. This is especially important in veterinary medicine and biology, as accurate terminology allows for clear communication regarding anatomy and procedures among professionals.

The other terms refer to different anatomical locations: "palmar" pertains to the palm side of the forelimb (the front legs of animals), while "plantar" relates to the sole of the hind limb (the back legs). "Medial" refers to something that is closer to the midline of the body, which does not specifically denote a part of the animal's back. Understanding these distinctions is crucial for identifying anatomical features and discussing animal health accurately.
