The long thoracic nerve descends through the cervicoaxillary canal. It is posterior to the brachial plexus, [3] and the axillary artery and vein. [4] This takes it deep to the clavicle. [2] It rests on the outer surface of the serratus anterior muscle. It extends along the side of the thorax to the lower border of the serratus anterior muscle ...
To the right is the azygos veins and thoracic duct, and to the left is the left pleura and lung. In front of the thoracic aorta lies the root of the left lung, the pericardium, the esophagus, and the diaphragm. The esophagus, which is covered by a nerve plexus lies to the right of the descending thoracic aorta. Lower, the esophagus passes in ...
The anterior internal vertebral venous plexus [2] consists of two large plexiform veins situated upon the posterior surfaces of the vertebral bodies and intervertebral discs on either side of the posterior longitudinal ligament (underneath this ligament they are interconnected by transverse branches into which the basivertebral veins open).
Thoracic outlet syndrome; The right brachial plexus, viewed from in front.: Specialty: Vascular surgery, thoracic surgery: Symptoms: Pain, weakness, loss of muscle at the base of the thumb, swelling, paleness, bluish coloration [1] [2]
The intercostal nerves are part of the somatic nervous system, and arise from the anterior rami of the thoracic spinal nerves from T1 to T11. [1] [2] The intercostal nerves are distributed chiefly to the thoracic pleura and abdominal peritoneum, and differ from the anterior rami of the other spinal nerves in that each pursues an independent course without plexus formation.
The brachial plexus is a superolateral relation of the thoracic outlet. The brachial plexus emerges between the anterior and middle scalene muscles, superior to the first rib, and passes obliquely and inferiorly, underneath the clavicle, into the shoulder and then the arm.
