The root
of the neck and the thoracic outlet:
The beginning of the chest cavity boundaries: the first paragraph bra and the first pair of ribs and the upper front of the rib bone. And sometimes called: thoracic outlet or thoracic inlet any entrance or exit the chest because members enter the chest and graduated from the chest of this place.It is an important place because there are members of the task gather all in a small place like the carotid artery and the artery under scapula and the trachea and esophagus and veins large, so the if the example tumor at the top of the lung or tumor in the thyroid gland, it will cause problems with the members around.scalenus anterior muscle or cervical rib may affect the vein under the scapula or a neural network gibbet when it enters the arm above the first rib.
scalenus muscles:
scalenus anterior muscleArising from Alentae lateral cervical vertebrae number 3, 4, 5, 6, and stick to the place allotted to the front edge of the first rib and by a thin tendon. Raise the first rib and neck administration on the same side.
scalenus medius muscle:Are the three biggest muscle, arising out of the back of the average extrusion of cervical vertebrae 2, 3, 4, 5, 6 and 7 does all cervical vertebrae except the first paragraph named Atlas, and stick to the upper face of the first leg in a broad place. Work: raising the first rib and neck administration on the same side.
scalenus posterior muscle:Small muscle stick second . Work: lifting the second leg.

As we can
see, the scapula artery sublavian artery and lower trunk of the neural network gibbet lower trunk of the brachial plexus passing of muscle between the hole is
not deep, but shallow in the upper surface of the
first leg and this shallow hole located between the muscles mentioned.
Scapula artery and the first thoracic nerve Akunan more vulnerable than others in this region to be affected because they Due to be passed over the first rib then Anhanian down to Ivhba in their way to the outside of the chest.
There may be what is known as cervical rib any rib rib be glued seventh cervical paragraph, if this exists, the scapula artery and lower Allowaljza of neural network gibbet, they are going through it then went to the bottom so Tqoshma will be more.
Even if this is not the rib (neck) is present, the scalenus anterior muscle muscle be sharp edge has put pressure on the artery and nerve. This pressure will lead to that man complains that his hands Bardtin Mzarktin and possible happen atrophy and weakness in the small muscles in the hand (these muscles fueled nerve T1 which are going fibers in the nerve average median nerve and nerve ulnar nerve, as well as a sense of Palm and numbness in the hand and the bottom arm on the medial side of the small fingers.
