**The following statements concerning the superior mediastinum is correct:
It contains the aortic arch
Esophagus passes through the superior mediastinum
Structures that are located in the anterior mediastinum :
some lymph nodess**
**The following statements concerning the heart is correct:
The apex of the heart lies in the left fifth intercostal space
It is supplied by the vagus nerve
The upper end of the right ventricle is known as the conus arteriosus
The coronary arteries are the branches of the ascending aorta
the heart has four chambers
It rests on the central tendon of**
diaphragm(at the front of the list of central cord)
Blood is returned to the left side of the heart by the:Pulmonaryveins
the apex is mostly made of left ventricle
chordae tindanea is strong non contrctile collagen fiber arise from top of papillary muscle
coronary sinus lies posterior to coronary sulcus
The following structures are found in the right atrium:
1. The anterior internodal tract
2. Atrioventricular node
- *3. Sinuatrial node
- ———————————————————**
The following structures are opened into the right atrium:
1. inferior vena cava
2. coronary sinus
- *The following valves** guards the opening between the right atrium and right ventricle:
**Tricuspid valve
The following valves guards the opening between the left atrium and left ventricle:**
Mitral valve
The following valves guards the opening between the left atrium and left ventricle:
Mitral valve
**Correct statements about the azygos vein :
it drains the right posterior intercostal
It arches over the right pulmonary root
It is located in the posterior mediastinum**
The following structures are supplied by the phrenic nerve:
1. pericardium
2. mediastinal parietal pleura
3. peritoneum covering the central region of the undersurface of the diaphragm
4. diaphragm
Correct statements about arch of the aorta:
it passes behind the manubrium sterni
it arches over the left pulmonary root
ligamentum arteriosum connects the arch and the left pulmonary artery
remnants of the thymus may be found in front of the arch
**Correct statements about the left vagus nerve :
It passes onto**
- *anterior** surface of the esophagus
- *Is** passes behind the root of the left lung
it cros the left side of aortic arch
Correct statements about tricuspid valve:
it is the largest of the valve orifice
the anterior leaflets is largest
chordae tendineae are inserted into ventricular aspect of the valve leaflets
septal papillary muscle is occasionally absent
the anterior leaflets is attached to the atrioventricular junction
The following statements concerning the cardiac annulus fibrosus are correct :
It supports the valves of the heart
It permits passage of the atrioventricular bundle
It completely separates atrial musculature from the ventricles
It provides the point of attachment for the cardiac muscle
right fibros trigon is between aortic ring and left atrioventricular ring
The following statements concerning the superior vena cava is correct:
It is formed by the union of the left and the right brachiocephalic vein
It receives the drainage from the upper limbs, head and neck
The following statements concerning the atrioventricular node is correct:
The anterior internodal tract enters the atrioventricular node
**The anterior interventricular branch is usually accompanied by the:
great cardiac vein**
Cardiac plexuses receive contributions from all the following:
Left vagus nerve
Right vagus nerve
Sympathetic trunk
Cervical sympathetic ganglia
**Upper thoracic ganglia
Recurrent laryngeal nerve**
not from phrenic
