RTE 1503 Chp 3 Chest review

QuestionAnswer
Radiographic anatomy of the chest is divided into three sections: Bony thorax, respiratory system proper, and the mediastinum
Anteriorly, the bony thorax consists of Sternum
Sternum has three divisions Superior(manubrium) center(body) and inferior (Xiphoid process)
Superiorly, the bony thorax consists of two clavicles connect the sternum to the two scapulae, twelve pairs of ribs that circle the thorax, and the twelve thoracic vertebrae posteriorly
For chest positioning, two landmarks are vertebra prominens and jugular notch
Four general divisions of the respiratory system pharynx, trachea, bronchi,and lungs
Each of the diaphragm is called Hemidiaphragm
Posterior area between the noise and mouth above and the larynx and esophagus below. Pharynx
Three divisions of the pharynx nasopharynx, oropharynx and laryngopharynx
Makes up the roof of the oral cavity Hard palate and soft palate
the posterior aspect of the soft palate is called the Uvula
Part of the digestive system that connects the pharynx with the stomach Esophagus
Xiphoid process corresponds to the level of ___ or ____ of the thoracic spine T9 or T10
Placement of the midthorax at the level of ____ of the thoracic vertebra. T7
Passage way for both food and fluids, as well as for air. Pharynx
Lies above and posterior to the larynx and extends from the upper border of the epiglottis Laryngopharynx
Part of the digestive system that connects the pharynx with the stomach and posterior to the larynx and trachea Esophagus
Laryngeal prominence of the thyroid cartilage located at approximately the level of ____ C5
Flips down and covers the trachea during the act of swalloing Epiglottis
which primary bronchus is wider and shorter and allows for foreign objects to enter Right primary bronchus
A specific prominence, or ridge of the lowest tracheal cartilage Carina
At what level is the carina located T5
Inner layer that covers the surface of the lungs and other organs Visceral pleura
The potential space between the double-walled pleura Pleural cavity
At what level do the apices of the lungs extend up to T1
The _______ of each lung is the lower concave area of lung that rests on the diaphragm Base
The ______ refers to the extreme outermost lower corner of each lung, where the diaphragm meets the ribs costophrenic angle
Radiographic important structures located in the mediastinum are the Thymus gland, heart and great vessels, trachea and esophagus
Air or gas present in this pleural cavity results in a condition called pneumothorax
PA chest, which must be taken with the IR placed crosswise Hypersthenic
Near average body habitus Hyposthenic
General rule for average adult patients is to show a minimum of ____ ribs on a PA chest radiograph 10
Three reasons why all chest radiographs should be taken in an erect position Diaphragm is allowed to move down farther, air & fluid levels may be seen, and engorgement/Hyperemia of pulmonary vessels may be prevented
