The inspiratory muscles are the diaphragm, external intercostals and parasternal internal intercostal muscles. The internal intercostals and abdominal muscles are expiratory. The ability of a subject to take one breath depends on the balance between the load faced by the inspiratory muscles and their neuromuscular competence. The ability of a subject to sustain the respiratory load over time (endurance) depends on the balance between energy supplied to the inspiratory muscles and their energy demands. Hyperinflation puts the diaphragm at a great mechanical disadvantage, decreasing its force-ge

The main goal of management of pleural effusion is to provide symptomatic relief removing fluid from the pleural space. The options depend on type, stage, and underlying disease. The first diagnostic instrument is the chest radiography, while ultrasound can be very useful to guide thoracentesis. Pleural effusion can be a transudate or an exudate. Generally, a transudate is uncomplicated effusion treated by medical therapy, while an exudative effusion is considered complicated effusion and should be managed by drainage. Refractory non-malignant effusions can be transudative (congestive heart fa

31-year-old man with a history of hypertension that was diagnosed at age 10 Sagittal oblique VR images (Figure 16.12.1) and a partial volume MIP image (Figure 16.12.2) from 3D CE MRA reveal severe focal narrowing of the proximal descending thoracic aorta just distal to the origin of the left subclavian artery. Note also enlarged internal mammary and intercostal arteries representing sources of collateral blood flow to the descending aorta....

Breast tissue develops from ectoderm, the primary mammary buds being noted during the fifth week of gestation. Glandular epithelium, stroma, and fat receive blood from the internal mammary and posterior intercostal arteries. In females, estrogen mediates ductal development. In males, androgen leads to destruction of the epithelial component of the breast bud. Most breast complaints are due to a mass, nipple discharge, or pain. Ultrasonography is useful in young women and as an adjunct to mammography. Wide local excision, mastectomy, sentinel lymph node biopsy, and axillary dissection can be useful in men and women undergoing breast surgery. Lymphedema may occur after axillary lymph node dissection or radiation therapy.

The thorax is the region of the body commonly known as the chest between the neck and the abdomen. The thoracic cavity is the hollow in the thorax that is occupied by the thoracic viscera, the heart and its associated vessels in the midline, and the lungs laterally. The thoracic viscera are enclosed by the bony and muscular thoracic cage. The bony components of the cage are the 12 thoracic vertebrae posteriorly, the 12 pairs of ribs and their anterior cartilaginous extensions, the costal cartilages that meet the sternum anteriorly. The intercostal muscles fill the intercostal spaces between the ribs and are involved in ventilation. Another muscle involved in ventilation is the diaphragm, a sheet of muscle that separates the thoracic from the abdominal cavity. If you are not familiar with the basic outline and arrangements of the circulatory and respiratory systems, refer back to Chapters 4 and 5 before reading this section. A good way to appreciate where these structures lie in relation to each other is to examine their surface anatomy, the position of internal organs related to features that can be observed or palpated (felt) on the surface of the body. Relating surface anatomy to deeper structures is a clinical skill essential not only to the study of the thorax, but also of structures in the head and neck important in dental practice. In the clinical examination of the living subject, the position of the internal thoracic organs is defined with reference to a set of vertical and horizontal lines running through the surface of bony landmarks. The significant vertical lines are shown in Figure 9 .1 as the: 1. Mid-sternal line—in the median plane anteriorly; 2. Mid-clavicular line—through the midpoint of the clavicle; 3. Mid-axillary line—midway between the anterior and posterior axillary folds, formed from skin overlying muscles. If you raise your arm while looking into a mirror, the two folds are obvious; they can also be palpated very easily even with clothes on. 4. Median posterior line—in the median plane anteriorly. The horizontal position can be defined with reference to the ribs or, less easily, the vertebrae.
