The muscles of the trunk include those that move the vertebral column , the muscles that form the thoracic and abdominal walls, and those that cover the pelvic outlet.
The erector spinae group of muscles on each side of the vertebral column is a large muscle mass that extends from the sacrum to the skull. These muscles are primarily responsible for extending the vertebral column to maintain erect posture.

As for using the words in your original sense to describe an object such as the one depicted below , I think you were onto something when you said we'd be more likely to travel with a trunk than with a chest , but I might use either word to describe the object in the picture. Both words overlap in meaning but also have some very different alternate definitions, and dictionaries notoriously don't give the nuance that is obvious to native users of the words.
A chest is - a large reinforced container of a certain size - a large piece of furniture for holding clothes a chest of drawers - the thorax the lungs, heart and breast area considered from the front. From the back it is referred to as the upper back. A trunk is - a large reinforced container of that same general size, so synonymous - the enclosed storage area in a car in American English - the main part of a tree coming out of the ground and by analogy any large cylindrical conduit or linearly organized central 'thing'.
Because of these many meanings, an ngram comparison will be very misleading who knows which meaning is being used? For the thing one travels with, 'chest' or 'trunk' feel equally interchangeable especially given that one normally just uses a 'suitcase' nowadays.
On reflection, it feels like 'trunk' would be more likely to call the thing you travel with as it is also a synonym for a 'suitcase', but chest is not. For the anatomical regions, even when used informally and not technically, 'chest' is much more common; one is more likely to refer to the specific area, chest or abdomen the lower part of the trunk rather than the entire trunk.
A chest has connotations of keeping valuables safe, a tradesman would keep his tools locked in a tool-chest for example. A trunk would usually be used for clothes, and would be lined in some way to prevent them from being torn.
Traditionally it would be covered in leather. Sign up to join this community. The best answers are voted up and rise to the top. Stack Overflow for Teams — Collaborate and share knowledge with a private group.
