THORAX Meaning and
Definition
-
The thorax is a noun referring to the middle section of an insect's body or the part of the human body containing the heart, lungs, and other vital organs. In entomology, it corresponds to the area between the head and the abdomen of an insect, composed of three segments: the prothorax, the mesothorax, and the metathorax. The thorax serves as the attachment site for the insect's wings and legs, providing support and mobility. It is protected by a tough exoskeleton that helps maintain the insect's shape and structure.
In human anatomy, the thorax is the region between the neck and the abdomen, bounded by the ribs and the diaphragm. It encompasses three major cavities: the pericardial cavity, which houses the heart, the pleural cavities, containing the lungs, and the mediastinum, housing other important structures such as the esophagus and major blood vessels. The thorax plays a crucial role in respiration, as it houses and protects the vital organs involved in the process. It also provides attachment points for various muscles, allowing for movement of the arms and shoulders. Overall, the thorax serves as a vital hub for multiple physiological functions and structural support within the human body.
