Cause of Death: Fall from a height into water. Figure 3.73. Eight fused cranial bones together form the cranial cavity: the frontal, occipital, sphenoid and ethmoid bones, and two each of the parietal and temporal bones . 3.27). 3.59). The thoracic spine is composed of 12 vertebrae sharing intervening intervertebral discs and connected posteriorly and bilaterally via facet joints. FT-5, VR image of the lateral view of the bones of the lower limbs showing bilateral transverse fractures of the proximal fibulae, in addition to a lateral malleolus fracture of the left fibula and fracturing of the right calcaneus and cuboid (red arrows). 3.53). Table V benchmarks the method’s computation time for the three test CT scans, using the Dell Precision T5500 workstation mentioned previously. Figure 3.63. Figure 3.38. 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. FT-7, anterolateral view of the right thigh showing a bruise. The chest cavity expands by the actions of the intrathoracic musculature, innervated from T1 to T11 and the diaphragm innervated by the phrenic nerve (C3–C5).

Figure 3.5. The heart may have superficial petechial hemorrhages and ruptures, even to the left ventricular wall. It is in the thoracic cavity that the heart distributes blood for general circulation and the major veins collect and transport blood back to the heart. The thoracic cavity is further divided into separate parts. Figure 3.96. FT-9, VR image of the anterior left clavicle showing an oblique fracture of the acromial end. FT-8, VR images of the six standard views of the skull showing a full-thickness linear fracture of the left frontal bone, which radiated superiorly and inferiorly from the point of impact (orange arrow). The parietal pleurae overlying the segmental vessels are swept away with a monopolar coagulator (Fig. Note the many membranes lining the coelom and holding the organs in place. Trapping of the individual’s chest due to his position underneath the train restricted his breathing (traumatic asphyxia). The posterior view shows fractures of the left and right transverse processes (red arrows), a fracture of the spinous process of the 9th thoracic vertebra (blue arrow), and a “Smith” fracture of the left facet of the 10th thoracic vertebra (blue arrow). The diaphragm forms the inferior border of the thoracic cavity, separating it from the abdominal cavity below. 3.51), both of which have been recorded to result from direct compression forces following a fall from height (Atanasijevic et al., 2009). 3.44). The fractures of the vertebrae were of the type seen in axial trauma with a buttock-first impact (Goonetilleke, 1980). FT-2, anterior view of the chest and arms showing minor cutaneous injuries to the right breast, right upper arm, and the suprapubic region. The right ventricle is the more muscular of the right-sided chambers, but is thin walled compared to its left-sided counterpart. The thoracic aorta gives off multiple vessels before exiting the thoracic cavity, including arteries to supply the pericardium, bronchi, mediastinum, and esophagus; it also gives off the superior phrenic arteries, posterior intercostal arteries, and subcostal arteries. 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). FT-6, posterior view of the buttocks and thighs (left) and the lower legs (right) showing extensive bruising.

The skull exhibited comminuted fracturing of the face, mandible, and cranial vault (Fig. Sensitivity of thoracic-cavity segmentation as function of the number of seeds n in seed set S per . Venous blood from the head, neck, and upper limbs returns to the thorax via the confluence of subclavian and internal jugular veins to form the left and right brachiocephalic vein, which in turn join to form the superior vena cava. Traumatic dissection of the coronary arteries and carotid arteries can occur. Intervertebral discs . The cranial cavity, or intracranial space, is the space formed inside the skull. There were fractures and disruption of the left hemipelvis (Fig. Thoracic cavity trauma showed a full-thickness transverse fracture of the body of the manubrium (Fig. While these functions can slightly vary from person to person, they typically are as follows: T1 and T2 (top two thoracic nerves) feed into nerves that go into the top of the chest as well as into the arm and hand. Figure 3.67. When this happens, organ and circulatory walls allow plasma/water to pass freely throughout the thoracic cavity, so its pressure stays constant and the organs aren't crushed. FT-7, posterior lateral view of the left lower back showing a bruise/abrasion with deformity of the underlying left pelvic bones. The thoracic cavity (or chest cavity) is the chamber of the body of vertebrates that is protected by the thoracic wall (rib cage and associated skin, muscle, and fascia). Additionally, there was a superficial laceration 3 cm long located inferior to the left eye. Trauma to the face involved diastatic fractures of the right zygomatic with slight lateral displacement and multiple fractures of the body of the mandible (see Fig. The posterior location of most of the rib fractures suggested that the direct force to the ribs was applied to the back of the chest (Atanasijevic et al., 2009). The rib head is drilled away and the shell is removed with a curette. The stomach, intestines, liver, gall bladder, pancreas, spleen, and kidneys are in the abdominal cavity. 3.23). After the hemoclips are applied to both sides, the vessel is cut and retracted. From Applegate, 2000. abdominal cavity the cavity of the body between the diaphragm above and the pelvis below, containing the abdominal organs. Authors Ronnarit Cheirsilp 1 , Rebecca … 3.68). 3.52). In forced inspiration, the pressure in the intrapleural space may fall to as low as 30 mmHg.

CT gives anatomical details on diagnostic regions of interest (ROIs), while PET gives highly specific functional information. All fractures were full-thickness. Hemothorax is generally acute and fatal. Figure 3.3. Before opening the chest and pleural cavities, the possibility of a pneumothorax should be remembered, and appropriate investigation methods applied. Spinal fractures involved the cervical, thoracic, and lumbar vertebrae. 3.25), and trauma to the thoracic cavity comprised multiple rib fractures, primarily to the left side (Fig. Figure 3.23. 3.90). Flashcards. Some investigators advocated the use of 2-mm instruments, reporting greater patient satisfaction rates, reduced operative time, and a decreased incidence of complications from compensatory hyperhidrosis and Homer’s syndrome.33,34 However, drawbacks are increased fragility of the instrument and limited visibility.35 Because landmark identification is key in accident avoidance, an instrument with an adequate field of view is extremely important.36. Vertebral trauma comprised full-thickness fracturing of the body and laminar of the 7th cervical vertebra (Fig. FT-10, anterior view of the head showing suffusion of the face (traumatic asphyxia). Figure 3.75. The rib fractures on the left comprised the following: Figure 3.78. 3.54). This indicated a high-velocity impact to the back of the head (Kranioti, 2015). The thoracic cavity protects and holds the lungs, heart, trachea, esophagus, endocrine glands, thoracic aorta and the pulmonary artery. The pelvic girdle showed extensive disruption (Fig. Figure 3.37. This pressure can be determined by connecting a balloon catheter with the balloon in the oesophagus at the level of the mediastinum to a pressure transducer. Other than Bradycardia and Peripheral vasoconstriction, there is a blood shift which occurs only during very deep dives that affects the thoracic cavity (a chamber of the body protected by the thoracic wall.) This cavity is separated from the abdominal cavity by a dome-shaped muscle located underneath the rib cage. The CT scan also showed a full-thickness fracture of the left transverse process of the 1st thoracic vertebra (Fig. The left leg shows an oblique fracture of the medial malleolus of the tibia and lateral malleolus of the fibula (red arrows). There were also multiple fractures of the left clavicle, with inferior displacement of the acromial end (Fig. The term pleural refers to the membranous lining around the lungs that aids in their function.

Thoracic Cavity: The thoracic cavity is the cavity where the lungs and the heart are found. The heart consists of four chambers: the right and left atria, and right and left ventricles. Comment: The landing surface was deformable (water), and the individual was wearing a long skirt, singlet, and shirt. Thoracic cavity definition is - the cavity of the thorax that is bounded below by the diaphragm, is enclosed by the sternum, ribs, and thoracic vertebrae, and that contains the heart and lungs. Valverde Celia R., Christe Kari L., in The Laboratory Primate, 2005. 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. 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. Epub 2015 Apr 23. The lacerations were associated with gross compound fracturing of the facial skeleton. FT-3, anterior view of the head showing an abrasion and bruising to the left cheek and bruising to the left periorbital region and forehead. 3.30) and bilateral abrasions over the anterior lower limbs with a circumferential laceration of the right ankle associated with fracturing (Fig. Thank you for watching and supporting! 3.49).
