Schnell und sicher online buchen. Oblique in Sinaia buchen Clinical Relevance: Transverse Pericardial Sinus. Formed as a result of the embryological folding of the heart tube, the transverse pericardial sinus is a passage through the pericardial cavity.. It is located: Posterior to the ascending aorta and pulmonary trunk. Anterior to the superior vena cava. Superior to the left atrium. In this position, the transverse pericardial sinus separates the. Pericardial Sinuses. The pericardial sinuses are not the same as 'anatomical sinuses' (such as the paranasal sinuses).They are passageways formed the unique way in which the pericardium folds around the great vessels.. The oblique pericardial sinus is a blind ending passageway located on the posterior surface of the heart.; The transverse pericardial sinus is found superiorly on the heart

The oblique pericardial sinus can be found within the pericardium, between the left and right veins. The superior pulmonary veins return blood from the upper lobes of the lung, with the inferior veins returning blood from the lower lobes. TeachMe Anatomy. Part of the TeachMe Series The oblique sinus is the posterior extension of the pericardium and lies posterior to the left atrium and anterior to the esophagus. The transverse sinus lies superior and anterior to the oblique sinus. However, the transverse and oblique sinuses do not communicate at this level and are separated by two pericardial reflections (, Fig 11) Pericardium, transverse sinus and oblique sinus The paranasal sinuses are air-filled extensions of the nasal cavity. There are four paired sinuses - named according to the bone in which they are located - maxillary, frontal, sphenoid and ethmoid. Each sinus is lined by a ciliated pseudostratified epithelium, interspersed with mucus-secreting goblet cells

The oblique sinus is akin to lesser sac supporting the stomach and develops as an effect of absorption of 4 pulmonary veins into the left atrium. The oblique sinus permits the distension of left atrium during return of oxygenated blood in it from the lungs. Boundaries. Oblique sinus of pericardium is bounded in the following ways The four pulmonary veins are incorporated into the left atrium, forming the smooth inflow portion of the left atrium and the oblique pericardial sinus. Aortic Arches The early arterial system begins as a bilaterally symmetrical system of arched vessels, which then undergo extensive remodeling to create the major arteries that exit the heart External Oblique. The external oblique is the largest and most superficial flat muscle in the abdominal wall. Its fibres run inferomedially. Attachments: Originates from ribs 5-12, and inserts into the iliac crest and pubic tubercle. Functions: Contralateral rotation of the torso. Innervation: Thoracoabdominal nerves (T7-T11) and subcostal. The pectoral region is located on the anterior chest wall. It contains four muscles that exert a force on the upper limb: the pectoralis major, pectoralis minor, serratus anterior and subclavius. In this article, we shall look at the anatomy of the muscles of the pectoral region - their attachments, actions and innervation

Gross anatomy. The superior thoracic aperture is kidney-shaped and lies in an oblique transverse plane, tilted anteroinferiorly to posterosuperiorly. It is roughly 10 cm in transverse dimension and 5 cm in AP dimension Gross anatomy. The inferior thoracic aperture is irregular in shape and is more oblique and much larger than the superior thoracic aperture.The diaphragm occupies and closes the inferior thoracic aperture, thereby separating the thoracic and abdominal cavities. For structures to pass between the two cavities, they either pass behind the diaphragm or pass through various diaphragmatic apertures The cardiac plexus is a plexus of nerves situated at the base of the heart.. It is formed by cardiac branches derived from both the sympathetic and parasympathetic nervous systems. Gross anatomy. Sympathetic cardiac nerves are derived from T1 to T4 segments and partly from the T5 segment of the spinal cord.They are the stimulators of cardiac function

The main changes concern the lower boundary of station 1 (thoracic inlet with sagittal oblique plane preferred to the clavicles) and the lower boundary of the station 4 (it should be on the right side of the inferior border of the azygos vein, and on the left side of the superior border of the left main pulmonary artery, but the result is. The papillary muscles are thick bands and ridges of endocardial-lined myocardium that project into the lumen of the cardiac ventricles.They essentially represent dominant ventricular trabeculae which attach to the cusps of the atrioventricular valves via the chordae tendineae.During systole, they contract to close atrioventricular valves and prevent the valves from prolapsing Gross anatomy. The thoracic duct is the superior continuation of the cisterna chyli at the level of the L1 vertebral body (range T10-L3).. The thoracic duct enters the thoracic cavity through the aortic hiatus and ascends to the right of the midline in the posterior mediastinum between the aorta and azygos vein, posterior to the esophagus.. It crosses to the left of midline at the thoracic. The interchondral joints are small articulations between the apposed costal cartilages of the ribs 7-10.. On each side are three diminutive synovial joints between the surfaces of the 6 th and 7 th costal cartilages, 7 th and 8 th costal cartilages and 8th and 9th costal cartilages. The 9 th and 10 th costal cartilages are interconnected by tough ligamental bands, the intercostal ligaments.

Pericardial sinuses (or folds) between the atria and great vessels can give rise to echolucent spaces despite only minimal amounts of pericardial fluid.

1, 3,5 With the development of the percutaneous epicardial ablation and cardiac resynchronization therapy, exact knowledge of the pericardial anatomy along with surrounding structures is important. The pericardial recesses can be categorized on the ba- sis of whether they arise from the pericardial cav- ity proper, the transverse sinus, or the oblique sinus. The transverse sinus lies posterior to the ascending aorta and main pulmonary artery, just above the left atrium. The oblique sinus is the ascending aorta, and SVC (Fig 10) The pericardial sac has attachments to the posterior mediastinum formed by the oblique and transverse sinuses, which in turn form several recesses that fold over the great arteries and veins 4-8) as shown in Fig. 1. 9) There are several anatomical variations of these recesses, as shown in Fig. 2. 10

The CSF is produced by the choroid plexus which can be found in the two lateral ventricles, and in the roof of the third and fourth ventricles. Around 500 ml is produced each day, with around 150-250 ml being present in the body at any one time Between the parietal and visceral layers of the serous pericardium is the pericardial cavity, which contains a thin film of fluid. This film enables the pulsating heart to glide frictionlessly within the pericardium. The pericardial cavity has two prominent recesses: the transverse sinus and the oblique sinus The oblique sinus is bound by the inferior vena cava and the four pulmonary veins, which form a recess between the left atrium and the pericardium, and the transverse sinus which is between the superior vena cava and left atrium posteriorly and the pulmonary trunk and aorta anteriorly Circulation 67:1151, 1983 DeBakey ME, Diethrich EB, Liddicoat JE, et al: Abnormalities o the sinuses of Valsalva.
