The importance of a cervical rib is that it can cause pressure on the lower trunk of the brachial plexus in some patients, producing pain down the medial side of the forearm and hand and wasting of the small muscles of the hand. In the female after puberty, it enlarges and assumes its hemi- spherical shape. Note also the pres- ence of the costal groove along the inferior border of the rib. This joint is absent on the 11th and 12th ribs.

It can also exert pressure on the overlying subclavian artery and interfere with the circulation of anwtomy upper limb.

The inferior border, formed by the right ventricle and the apical part of the left ventricle, extends from the sixth right costal cartilage 0. Surface Anatomy 57 The internal thoracic vessels run vertically downward, posterior to the costal cartilages, 0.

In older women past menopause, the adipose sells sue of the breast may become reduced in amount and the hemispherical shape lost; the breasts then become smaller, and the overlying skin is wrinkled.

For the 2nd to 9th ribs, the head articulates by means of a synovial joint with the corresponding vertebral body and that of the vertebra above it see Fig. A second longitudinal incision is then made editoin the bed of the rib, which is the inner covering of periosteum.

Joints of the Tubercles of the Ribs The tubercle of a edihion articulates by means of a synovial joint with the transverse process of the corresponding ver- tebra see Fig.

Myocardial infarction commonly results in referred pain down the inner side of the arm or up into the neck.

The diaphragm, which is a very thin muscle, is the only structure apart from the pleura and the peritoneum that separates the chest from the abdominal viscera.

A rib has a head, neck, tubercle, shaft, and angle see Figs. A longitudinal inci- sion is made through the periosteum on the outer surface of the rib, and a segment of the rib is removed.

The inferior border overhangs and forms the costal groove, which accommodates the inter- costal vessels and nerve. Mediastinum The mediastinum, though thick, is a movable partition that extends superiorly to the thoracic outlet and the root of the neck and inferiorly to the diaphragm. Mammary Gland The mammary gland is clinically a very important struc- ture. A small amount of angular movement is possible during respiration.

Costal Cartilages Costal cartilages are bars of cartilage connecting the upper seven ribs to the lateral edge of the sternum and the 8th, 9th, and 10th ribs to the cartilage immediately above.

The xiphisternal joint is a cartilaginous joint between the xiphoid process cartilage and the body of the sternum. The opening clinocal bounded posteriorly by the 1st thoracic vertebra, laterally by the medial borders of the 1st ribs and their costal cartilages, and anteriorly by the superior border of the manubrium sterni. Joints of the Ribs Joints of the Heads of the Ribs The 1st rib and the three lowest ribs have a single syno- vial joint with their corresponding vertebral body.

It contains the remains clinial the thymus, the heart clnical large blood vessels, the trachea and esophagus, the thoracic. After the operation, the rib regen- erates from the osteogenetic layer of the periosteum. Acquired herniae may occur in middle-aged people with weak musculature around the esophageal opening in the dia- phragm.

Atypical Rib The 1st rib is important clinically because of its close rela- tionship to the lower nerves of the brachial plexus and the Basic Anatomy 37 lamina pedicle facet for rib tubercle transverse process spinous process inferior articular process inferior vertebral notch demifacet for rib head body of vertebra demifacet for rib head superior articular process heart-shaped body demifacet for rib head superior articular process facet for rib tubercle transverse process spinous process A B FIGURE 2.

Rib Excision Rib excision is commonly performed by thoracic surgeons wish- ing to gain entrance to the thoracic cavity.

The costal cartilages contribute significantly to the elas- ticity and mobility of the thoracic walls. It may have a free anterior end, may be connected to the 1st rib by a fibrous band, or may articu- late with the 1st rib. It extends upward into the root of the neck about one fingerbreadth above the clavicle on each side see Fig. Anterior to the scalenus anterior, the subclavian vein crosses the rib; posterior to the muscle attachment, the subclavian artery and the lower trunk of the brachial plexus cross the rib and lie in contact with the bone.

During the course of the examination, she said that she could also feel the pain in her back between the shoulder blades.
