What is the difference between direct thermal and thermal transfer printing? There are two thermal printing methods: direct thermal and thermal transfer. Each method uses a thermal printhead that applies heat to the surface being marked. Thermal transfer printing uses a heated ribbon to produce durable, long-lasting images on a wide variety of materials.

Thoracic Cage. Introduction. The thoracic cage (rib cage) is the skeleton of the thoracic wall. It is formed by the 12 thoracic vertebrae, 12 pairs of ribs and associated costal cartilages and the sternum. The thoracic cage takes the form of a domed bird cage with the horizontal bars formed by ribs and costal cartilages. It is supported by the vertical sternum or breastbone (anteriorly) and the 12 thoracic vertebrae (posteriorly). The thoracic cage can also be described as an osteocartilaginous cage formed by the sternum, 12 pairs of ribs and costal cartilages, 12 thoracic vertebrae and the intervertebral (IV) discs interposed between them.
