Used when discussing human biology or describing injuries to the body's middle section.

Human Anatomy

Refers to the area protecting critical organs; context often medical or related to harm.

Protected Organs

Common in healthcare, less used in everyday language where 'chest' is more typical.

Medical Context

Used to describe the body section of insects and some arthropods, between head and abdomen.

Animal Anatomy

Remember, 'thorax' isn't used for all creatures; it's specific to certain groups like insects.

Not for All Animals

In the context of zoology, it often refers to a distinct segment separate from the abdomen.

Segmented Bodies

 body is only marginally more pink and the blue leaves and moss around her but she has a special way of warming up for flight she can put her wings out of gear so that without moving them she can rev up the wing muscles inside and that raises the temperature within her thorax

The real reason why...

 powerful muscles in the Dragons thorax reorient the wings into their final horizontal position the dragonfly is now almost ready to take its maiden flight
