Which is not a branch of thoracic aorta?

The right coronary artery:

Is accompanied by the great cardiac vein

Usually supplies a part of the anterior wall of the left ventricle

Usually supplies an anterior part of the interventricular septum

Usually supplies the majority of the left atrium

Goes with the small cardiac vein

The 7th right intercostal space:

Is supplied by anterior intercostal artery, a direct branch of internal thoracic aorta

Is supplied by anterior intercostal artery, direct branch of superior epigastric artery

Is supplied by anterior intercostal artery, a direct branch of musculophrenic artery

Is supplied by anterior intercostal artery, a direct branch of abdominal aorta

Has only posterior intercostal artery

In the intercostal space:

Intercostal nerve passes between the innermost muscle and the internal space

Innermost intercostal muscle is attached to the external margin of costal groove

External intercostal muscle is attached to the internal margin of costal groove

Intercostal nerve has the highest position in the costal groove

Intercostal nerve has the middle position

What is FALSE about the conducting system of the heart?

Sinuatrial node lies anterior to the superior vena cava opening

Atrioventricular node lies between the mitral valve and interatrial septum

Bundle of Hiss pierces the atrioventricular part of the septum

Purkinje fibres stimulate the ventricles

Septomarginal trabecula transmits left bundle crus

Which are not a branches of internal thoracic artery?

Diaphragm:

It has two equal crura

The aortic aperture is on higher level than esophageal

It has only autonomic innervation

Azygos vein usually passes through the esophageal hiatus

The caval opening is at the level of TVIII

In the fetal circulation:

Umbilical vein transmits oxygenated blood to the placenta

Ductus arteriosus transmits blood from aorta to pulmonary trunk

Ductus venosus transmits blood to the superior vena cava

Umbilical vein changes into venous ligament

Umbilical vein transmits oxygenated blood

The male breast:

Has exactly the same structure like female breast

It remains rudimentary throughout life

It is formed of small ducts and many small, lobules or alveoli

The areola is week developed and the nipple is absent

The areola is absent

In the respiratory ways:

Each part of bronchial tree has cartilage in the wall

Left principal bronchus is wider and shorter than right one

Bronchial artery transmits deoxygenated blood

Pulmonary artery transmits deoxygenated blood

Right main broncus gives three lobar bronchi

Hemiazygos accessory vein:

Drains the first intercostal space

Ends in the third intercostal space

Usually ends in the 10th intercostal space

Directly terminates in the superior vena cava

Finally ends azygous vein

The terminal bronchiole

Is a direct branch of the main bronchus

Contains thin cartilaginous plates in the wall

Divides into segmental bronchi

Contains alveoli in the wall

All above are false

In the latercostal space:

Intercostal nerve passes between the innermost muscle and the endothoracic fascia

Is supplied by anterior intercostal artery, a direct branch of musculophrenic artery

Is supplied by anterior intercostal artery, a direct branch of abdominal aorta

All of the above are false

The right coronary artery:

Is accompanied by the great cardiac vein

Usually supplies a part of the anterior wall of the left ventricle

Usually supplies a posterior part of the interventricular septum

Usually supplies the majority of the atrioventricular bundle

All of the above are false

In the right lung you can find:

Pulmonary ligament projects superiorly from the hilum

Area for thymus under the hilum

Groove for azygos vein over the helium

Groove for aortic arch

All above are false

In the superficial layer of the back’s muscles, you can find:

Latissimus dors m. Innervated by accessory nerve

Trapezius m. Innervated by short branches of the brachial plexus

Semispinalis capitis m. Innervated by dorsal ramus

Rectus capitis m. Innervated by suboccipital nerve

None of the above

Choose a true sentence about the inferior lumbar trigone:

Laterally it is margined by internal oblique muscle

Superiorly it is margined by iliac crest

Medially it is margined by external oblique abdominal muscle

The floor it is formed by latissimus dorsi muscle

All of the above are false

The aortic hiatus:

Lies directly in front of lumbar vertebral column

Is limited by medial arcuate ligament
