Q

Thoracic Outlet

A

Where the subclavian artery and vein and the brachial plexus exit the thorax and enter the arm.
• They pass over the 1st rib and under the clavicle.
• The subclavian vein is the most anterior structure and is immediately anterior to scalenus
anterior and its attachment to the first rib.
• Scalenus anterior has 2 parts, the subclavian artery leaves the thorax by passing over the
first rib and between these 2 portions of the muscle.
• At the level of the first rib, the lower cervical nerve roots combine to form the 3 trunks of the
brachial plexus. The lowest trunk is formed by the union of C8 and T1, and this trunk lies directly posterior to the artery and is in contact with the superior surface of the first rib

Q

safe triangle’. The triangle is located in the mid axillary line of the 5th intercostal space. It is bordered by:

A

nterior edge latissimus dorsi,
the lateral border of pectoralis major,
a line superior to the horizontal level of the nipple,
and the apex below the axilla.

Q

Where is the Conus arteriosus

A

The conus arteriosus (infundibulum) is the smooth walled outflow tract of the right ventricle leading to the pulmonary trunk.

Q

Cervical ribs

A

Most cases present with neurological symptoms
• Consist of an anomalous fibrous band that often originates from C7 and may arc towards,
but rarely reaches the sternum
• Congenital cases may present around the third decade, some cases are reported to occur
following trauma
• Bilateral in up to 70%
• Compression of the subclavian artery may produce absent radial pulse on clinical examination and in particular may result in a positive Adsons test (lateral flexion of the neck towards the symptomatic side and traction of the symptomatic arm- leads to obliteration of radial pulse)
• Treatment is most commonly undertaken when there is evidence of neurovascular compromise. A transaxillary approach is the traditional operative method for excision.

18
Q

Angle of Louis (Manubriosternal angle), lies directly at this level

A

is the surface marking for the aortic arch. The oesophagus is posteriorly located and at less risk.

19
Q

Inferior borders of both lungs

A

6th rib in mid clavicular line
• 8th rib in mid axillary line
• 10th rib posteriorly
The pleura runs two ribs lower than the corresponding lung level.

20
Q

greatest proportion of musculi pectinati found

A

The musculi pectinati are found in the atria, hence the reason that the atrial walls in the right atrium are irregular anteriorly.
The musculi pectinati of the atria are internal muscular ridges on the anterolateral surface of the chambers and they are only present in the area derived from the embryological true atrium

21
Q

medial part of the clavicle

A

The subclavian vein lies behind subclavius and the medial part of the clavicle

22
Q

Superior vena cava obstruction

How many collateral

A

There are 4 collateral venous systems:
• Azygos venous system
• Internal mammary venous pathway
• Long thoracic venous system with connections to the femoral and vertebral veins (

23
Q

Structures passing through the lesser and greater sciatic foramina (medial to lateral): PIN

A

Pudendal nerve
• Internal pudendal artery
• Nerve to obturator

24

25
Q

Contents of the lesser sciatic foramen

A
  • Tendon of the obturator internus

Content of deep perineal pouch

A 
Obturator nerve
• Urethral sphincter
• Transversus perinei
• Dorsal nerve of penis, muscular branches of the perineal nerve
• Deep and dorsal arteries of penis,
27
Q

Medial malleolus

The following structures pass posterior to medial malleolus (in order):

A
  • Tibialis posterior tendon
  • Flexor digitorum longus tendon
  • Posterior tibial artery
  • Tibial nerve
  • Tendon of flexor hallucis
