Structure. In humans and other hominids, the thorax is the chest region of the body between the neck and the abdomen, along with its internal organs and other contents. It is mostly protected and supported by the rib cage, spine, and shoulder girdle. Contents


The Structure Of The Thorax. The thorax is a conical cavity with a rigid supporting skeleton (Pig. 68) formed by the dorsal vertebra behind, the breast bone in front, and the ribs and rib cartilages on the sides.


Thoracic wall. The first step in understanding thorax anatomy is to find out its boundaries. The thoracic, or chest wall, consists of a skeletal framework, fascia, muscles, and neurovasculature – all connected together to form a strong and protective yet flexible cage.. The thorax has two major openings: the superior thoracic aperture found superiorly and the inferior thoracic aperture ...

In vertebrates, thoracic vertebrae compose the middle segment of the vertebral column, between the cervical vertebrae and the lumbar vertebrae. In humans, there are twelve thoracic vertebrae and they are intermediate in size between the cervical and lumbar vertebrae; they increase in size going towards the lumbar vertebrae, with the lower ones being a lot larger than the upper.


The only difference between a fish thoracic cavity and ours is the presence of lungs. The fish thoracic cavity can be much smaller, without the presence of lungs. The gills are typically found much higher in the throat, often in the skull of bony fishes. The thoracic cavity of fish still houses many vessels and nerves as they transverse the body.


Surfaces (three) – These correspond to the area of the thorax that they face. They are named costal, mediastinal and diaphragmatic. Borders (three) – The edges of the lungs, named the anterior, inferior and posterior borders. Lobes. The right and left lungs do not have an identical lobular structure.


The thoracic cavity is basically the chest, including everything between the neck and the diaphragm. It’s home to the thoracic organs and is protected by the thoracic cage. The heart and lungs are essential for survival and both are prone to certain diseases, so you need to be able to examine them. The thoracic cavity […]


Thoracic cavity, also called chest cavity, the second largest hollow space of the body. It is enclosed by the ribs, the vertebral column, and the sternum, or breastbone, and is separated from the abdominal cavity (the body’s largest hollow space) by a muscular and membranous partition, the diaphragm.
