student Anatomy is a vast subject and, therefore, in order to achieve this goal, I have deliberately carried out a rigorous selection of material so as to cover only those of its thousands of facts which I consider form the necessary anatomical scaffolding for the clinician Wherever possible practical applications are... six intercostal spaces; those of the 2nd–4th spaces are large in the female and supply the breast The intercostal nerves are the anterior primary rami of the thoracic nerves, each of which gives off a collateral muscular branch and lateral and anterior cutaneous branches for the innervation of the thoracic and abdominal walls (Fig 9) Clinical features 1◊◊Local irritation of the intercostal nerves by... ciliated columnar epithelium with many goblet cells Clinical features Radiology Since it contains air, the trachea is more radio-translucent than the neighbouring structures and is seen in posteroanterior and lateral radiographs as a dark area passing downwards, backwards and slightly to the right In the elderly, calcification of the tracheal rings may be a source of radiological confusion Displacement... lumbar vertebrae and intervertebral discs; the left crus is only attached to the first two vertebrae The arcuate ligaments are a series of fibrous arches, the medial being a thickening of the fascia covering psoas major and the lateral of fascia overlying quadratus lumborum The fibrous medial borders of the two crura form a median arcuate ligament over the front of the aorta 2◊ A costal part is attached to... abdominal musculature which, acting through the contained viscera, forces the diaphragm upwards In deep and in forced inspiration additional muscles attached to the chest wall are called into play (e.g scalenus anterior, sternocleidomastoid, serratus anterior and pectoralis major) to increase further the capacity of the thorax Similarly, in deep expiration, forced contraction of the abdominal muscles aids... artery and vein and the two vagi; 3◊◊the opening for the inferior vena cava (T8) which is placed in the central tendon and also transmits the right phrenic nerve In addition to these structures, the greater and lesser splanchnic nerves (see page 49) pierce the crura and the sympathetic chain passes behind the diaphragm deep to the medial arcuate ligament The development of the diaphragm and the anatomy. .. aids the normal expulsive factors described above The pleurae The two pleural cavities are totally separate from each other (Fig 2) Each pleura consists of two layers: a visceral layer intimately related to the surface of the lung, and a parietal layer lining the inner aspect of the chest wall, the upper surface of the diaphragm and the sides of the pericardium and mediastinum The two layers are continuous... cervical vertebra) C6 Pre-vertebral fascia Carotid sheath (containing common carotid artery, internal jugular vein, and vagus nerve) with sympathetic chain behind and left carotid artery, both arising from the arch of the aorta, the left brachiocephalic (innominate) vein, and the thymus; •◊◊posteriorly—oesophagus and left recurrent laryngeal nerve; •◊◊to the left — arch of the aorta, left common carotid... rib has only one articular facet on the head The 11th and 12th ribs are short, have no tubercles and only a single facet on the head The 11th rib has a slight angle and a shallow subcostal groove; the 12th has neither of these features Clinical features Rib fractures The chest wall of the child is highly elastic and therefore fractures of the rib in children are rare In adults, the ribs may be fractured... carotid and left subclavian arteries, left recurrent laryngeal nerve and pleura; •◊◊to the right—vagus, azygos vein and pleura (Fig 17) Structure The patency of the trachea is maintained by a series of 15–20 U-shaped cartilages Posteriorly, where the cartilage is deficient, the trachea is flattened and its wall completed by fibrous tissue and a sheet of smooth muscle (the trachealis) Within, it is lined by a . my wife and late parents ECAPR 7/18/06 6:33 PM Page ii Clinical Anatomy A revision and applied anatomy for clinical students HAROLD◊ ELLIS
