At which bony point does the subclavian a. become the axillary a.?
Lateral border of first rib
In which area of the upper limb does the brachial artery branch into radial and ulnar aa.?
Cubital fossa
Of the radial and ulnar aa., which is the more superficial of the two?
Radial
oThe femoral artery a distal continuation of which artery?
External illiac artery
Where does the popliteal artery branch into the anterior and posterior tibial aa.?
Knee
The dorsalis pedis artery is a continuation of what?
The Anterior tibial artery on the dorsum of the foot (=pedis):
The posterior tibial a. enters the sole of the foot inferior to which malleolus of the ankle?
Medial malleous
What is the DVT the formation of?
A blood clot (thrombus) within a deep vein predominantly in the legs. Pulmonary embolism, a potentially life-threatening complication, is caused by the detachment (embolization) of the clot that travels to the lungs.
Into which major veins do a) the great and b) the small saphenous veins drain?
a) Femoral vein
b) Popiteal vein
What is a varicous veins?
Veins that have become enlarged and twisted. When veins become varicose, the leaflets of the valves no longer meet properly, and the valves do not work (valvular incompetence).
This allows blood to flow backwards and they enlarge even more. Varicose veins are most common in the superficial veins of the legs, which are subject to high pressure when standing.
What does ly,ph drain to?
The thoracic duct drains lymph from 3/4ths of the body to the medial end of the left subclavian vein.
The right lymphatic duct drains the right upper quadrant (1/4th) to the medial end of the right subclavian vein.
Where is the thoracic duct located?
On the vertebral bodies between the azygos vein and the descending thoracic aorta on the right side of the posterior thoracic wall (see image below).
The thoracic duct commences at vertebral level L1 as the cisterna chyli. It crosses the vertebral body of T4 from right to left and ascends to drain into the medial end of the left subclavian vein.
The parietal lymph of the thorax are the?
Parasternal, phrenic, and intercostal.
What are parasternal nodes?
Situated along the internal thoracic artery, receive lymphatics from the medial part of the breast, the intercostal spaces, the costal pleura, and the diaphragm
What are phrenic nodes?
Situated on the thoracic surface of the diaphragm. They receive lymphatics from the pericardium, diaphragm, and liver and drain into the parasternal nodes.
What are intercostal nodes are found?
At the vertebral end of the intercostal spaces
What is the lymph from heart wall drain to?
Right inferior tracheobronchial nodes and mediastinal (bronchopulmonary and paratracheal lymph nodes
