the anterior and posterior divisions join to form the _____, ______, and ______
lateral, posterior, and medial cords
what is thoracic outlet syndrome? what does this cause?
- neurovascular entrapment in the posterior cervical triangle and axillary regions
- this mechanical compression and increased pressure on the neurovascular structure can result in symptoms in UE
