What part of the body does the term 'trunk' refer to?

The term "trunk" specifically refers to the mid-portion of the body, which includes the thorax (chest) and abdomen. This central region houses vital organs such as the heart, lungs, and digestive organs. Understanding the anatomy of the trunk is essential because it provides the structural foundation for the entire body, connecting the limbs (arms and legs) to the head and neck. It serves as the core from which movements are generated and supports the spine, which is crucial for maintaining posture and balancing the body. Recognizing the trunk’s role in overall anatomy helps in various fields such as sports medicine, where knowledge of bodily regions is vital for assessment and treatment.
