What is Thorax?
The thorax is the middle part of an animal’s body, including humans, where the chest and back are located. It’s the section between the neck and the abdomen, housing vital organs like the heart and lungs in humans. In insects, the thorax is the segment between the head and the abdomen, where the wings and legs are attached.

Plural of Thorax
Both “thoraxes” (pronounced: THAW-rak-seez) and “thoraces” (pronounced: THAWR-uh-seez) are acceptable plurals of “thorax,” but they follow different pluralization rules. “Thoraxes” adheres to the conventional English practice of adding “-es” to form plurals for words ending in “-x,” as in “boxes” or “foxes.” On the other hand, “thoraces” mirrors the classical Latin pattern, where nouns ending in “-ax” change to “-aces” in the plural, such as “vertex” becoming “vertices.” Therefore, both “thoraxes” and “thoraces” are considered correct plurals for “thorax” in English. The choice between them may depend on personal preference, audience familiarity, or the specific context in which the term is used.
