Figure 3.42. Figure 3.35. The trachea bifurcates at the upper border of the 5th thoracic vertebrae into the left and right main bronchus, with each coursing inferolaterally to supply their respective lung. FT-3, lateral right view of the head showing an abrasion to the right cheek and bruising below the right eye. During the lung-cancer management p … Thoracic cavity definition for 3D PET/CT analysis and visualization Comput Biol Med. The skull exhibited comminuted fracturing of the face, mandible, and cranial vault (Fig. Mediastinum may be used to describe the middle section of the thoracic cavity which holds most everything but the lungs, including heart, great vessels, esophagus, trachea. The mediastinum. The thoracic cavity is further divided into separate parts. circulatory organ heart and major blood vessels. It is more common in… The lymph ducts in the thoracic cavity drain into the: a. cisterna chyli b. external jugular veins c. inferior vena cava d. junction of the brachiocephalic vein and the superior vena cava The thoracic diaphragm, or simply the diaphragm (Ancient Greek: διάφραγμα, romanized: diáphragma, lit. 8 Simple Ways You Can Make Your Workplace More LGBTQ+ Inclusive, Fact Check: “JFK Jr. Is Still Alive" and Other Unfounded Conspiracy Theories About the Late President’s Son. The pelvic girdle showed extensive disruption (Fig. Cause of Death: Multiple injuries as a result of being hit by a train. There was bruising observed over the left posterior lateral inferior chest (Fig. Function. Lateral: a full-thickness oblique fracture of the 11th rib; Anterior: a full-thickness oblique fracture of the 5th rib and a greenstick oblique fracture of the 6th rib. The coronary arteries should be examined properly with crosscutting, perhaps especially among the elderly. 3.93). There was also disruption of the spine between the 7th and 8th thoracic vertebrae, a spinous process fracture of the 9th thoracic vertebra, and a “Smith” fracture of the left superior articular facet of the 10th thoracic vertebra (see Fig. Determining whether rib fractures resulted from vertical deceleration forces (impact from the fall) or from horizontal deceleration forces (impact with the train) is difficult (Tomczak and Buikstra, 1999). FT-9, axial reconstructions of the 2nd thoracic vertebra (top left), 3rd thoracic vertebra (top right), 5th thoracic vertebra (bottom left), and 6th thoracic vertebra (bottom right) showing fractures of the left transverse processes (red arrows). 3.43). 3.72). There was also fracturing of the scapulae (Fig. Fractures are full-thickness, which resulted in extensive fragmentation of the vault with displacement, particularly on the right side. Circumstances: The individual ran and jumped into the path of a train that was pulling into a station. Figure 3.54. 3.11). It is the most common malformation of the chest cavity, with an incidence of 1 in 400 births. Fact Check: Is the COVID-19 Vaccine Safe? The first is to provide protection and support to the body’s vital organs. A diaphragm physically separates the two cavities the thoracic cavity contains respiratory organs lungs tracheae etc. 3.45). You are expected to have exhausted all possibilities in attempting to locate structures before asking for assistance. FT-10, anterior view of the lower limbs showing an abrasion to the right midthigh and multiple small bruises to both thighs. At the time the individual was wearing jeans, jumper, and closed footwear. 3.66) and multiple left rib fractures (Fig. Figure 3.96. FT-1, VR image of the posterior view of the bones of the right lower limb showing a full-thickness oblique fracture of the shaft of the right fibula (red arrow). Figure 3.87. Without this secretion, breathing would be difficult and painful. Figure 3.1. Pulls down to expand the lungs. 3.73). These vertebrae span the large majority of the chest cavity area. NB: frothy fluid is noted coming from the nostrils, which in the circumstances, was suggestive of drowning. 3.40). The trachea begins in the neck just below the cricoid cartilage at the level of the 6th cervical vertebrae, descending through the neck and thorax in the midline just anterior to the esophagus. Figure 3.55. There was a fracture–dislocation between the 7th cervical and the 1st thoracic vertebrae, which resulted in anterior displacement of the cervical spine (Fig. Cardiopulmonary resuscitation can cause a variety of injuries, such as fractures to the ribs, and laceration and hemorrhage of both hollow and solid organs. Figure 3.53. 3.4). 3.85). Each pleural cavity is lined by a pleural membrane consisting of two layers. 3.84). These comprised full-thickness transverse fractures of the distal 2nd to 4th metatarsals, distal 1st proximal phalanx, posterior body of the talus, and comminuted fracturing of the cuboid. On the chest, there was a bruise/abrasion complex over the right midanterior chest. Information from CT: Postmortem CT demonstrated fracturing of the skull, right radius and ulna, and left humerus. The lacerations were associated with gross compound fracturing of the facial skeleton. Figure 3.29. Enlarged thoracic aorta The thoracic cavity also contains the esophagus, which transports food and liquids from the throat to the stomach. 3.44). Comment: The landing surface was nondeformable (car park), and the position of the body on impact was unknown as the fall was not witnessed. Additionally, the right 10th thoracic vertebra had compression of the body with vertical fracturing (see Fig. This cavity is separated from the abdominal cavity by a dome-shaped muscle located underneath the rib cage. Figure 3.82. 2015 Jul;62:222-38. doi: 10.1016/j.compbiomed.2015.04.018. Figure 3.64. 3.3). Head: a full-thickness oblique fracture of the head of the 7th rib; Posterior: full-thickness oblique fractures of the 3rd to 5th and 8th to 11th ribs and full-thickness transverse fractures of the 6th to 7th and 12th ribs. There was a three-part Jefferson fracture (Beckner et al., 1998) of the 1st cervical vertebra with slight displacement of the posterior arch to the right and an odontoid fracture with a slight lateral displacement of the 2nd cervical vertebra (Fig. Surgery in which the thoracic cavity is opened to expose the heart and the blood is recirculated and oxygenated by a heart-lung machine. 3.41). Figure 3.67. Figure 3.13. Figure 3.99. The pond fracture comprised extensive radiating linear and concentric fractures involving multiple bones of the cranial vault and diastatic fractures primarily involving the coronal and squamosal sutures of the vault.
