The spinous processes of these vertebrae face obliquely downward (Figure 8-5 ). T7 has the greatest spinous process angulation, whereas the upper three thoracic vertebrae have spinous processes that project directly posteriorly. In other words, the spinous process of these vertebrae is on the ...
Thoracic vertebrae: The 12 vertebrae to which ribs attach Sternum: T-shaped flat bone located directly at the center of the chest. This is what is compressed during CPR to put force upon the heart. It has three parts, ordered below from top (closest to the head) to bottom (closest to ...
All other ribs are also connected to the thoracic vertebrae. The costovertebral joints are between the head of the rib, the vertebral body, and the intervertebral disc. The costotransverse joint is between the costal tubercle and the tip of the transverse process. The many different joint ...
TDH occurs when a disc bulges out from between your vertebrae. Discs are spongy cushions between the vertebrae in your spine. Thoracic discs are located between the base of your neck and your lower back. The herniated disc may press on your nerves or spinal cord....
In the living, the manubrium is to be found at the level of the third and fourth thoracic vertebrae and forms the anterior boundary of the superior mediastinum. The immediate relations of the upper part are therefore the thymus, left brachiocephalic vein and the brachiocephalic artery, left comm...
How is breathing affected if a bullet makes a hole in the thoracic cavity? Similarly, if there is a hole in the parietal pleura (like a bullet through the chest wall, for example), thatcan cause air to enter the pleural cavity directly from the outside. “Because that air has nowhere ...
It has hiatuses for the passage of the inferior vena cava ( caval hiatus), esophagus ( esophageal hiatus), and the aorta ( aortic hiatus) at the 8th, 10th, and 12th thoracic vertebrae respectively. The diaphragm is innervated by the phrenic nerve. Phrenic nerve palsy or injury to ...
How do the first two cervical vertebrae differ from other cervical vertebrae? What are their functions? Describe the location of the lungs, the lobes that each has, and how they fit in with the other structures in the thoracic cavity. Describe the membranes that are associated ...
The fat plain between the aorta and the vertebrae is lost (white arrow). Interventions are generally considered when the ascending thoracic aorta reaches 5.5 cm or the descending thoracic aorta reaches 6 cm in asymptomatic patients. Smaller aneurysms are followed annually, either by CT or magnetic...
an anatomically isolated cluster of nerve cells (neurons), nerve fibers, and tissues, found in many invertebrates, all vertebrates, and man. In vertebrates, ganglia are located along the nerve stems. Intervertebral ganglia, ganglia near the vertebrae, prevertebral ganglia, and ganglia enclosed in ...
