Furthermore, this procedure has resulted in restored function to nerves in the brachial plexus with minimal impact to respiratory function of the phrenic nerve. The instances where pulmonary vital capacity is reduced have typically been a result of use of the right phrenic as the donor for the neurotization whereas use of left phrenic nerve has ...
The caval opening of diaphragm [2] (also foramen of vena cava, [1] vena caval foramen [3] [1]) is an opening in the central tendon of diaphragm giving passage to the inferior vena cava [2] [3] as well as to some terminal [2] branches of [2] [1] the right phrenic nerve, [2] [3] and some lymphatic vessels en route to middle phrenic and mediastinal lymph nodes.

The diaphragm is primarily innervated by the phrenic nerve which is formed from the cervical nerves C3, C4 and C5. [7] While the central portion of the diaphragm sends sensory afferents via the phrenic nerve, the peripheral portions of the diaphragm send sensory afferents via the intercostal (T5–T11) [8] and subcostal nerves (T12). [citation ...
The subclavian nerve may issue a branch called the accessory phrenic nerve [3] [2] which innervates the diaphragm. [3] The accessory phrenic nerve may rather branch from the C4 or C6 segments or ansa cervicalis. [4] This nerve usually joins with the phrenic nerve before innervating the diaphragm, ventral to the subclavian vein. [5]
The phrenic nerve is a nerve essential for our survival which arises from nerve roots C3, C4 and C5. It supplies the thoracic diaphragm , enabling breathing . If the spinal cord is transected above C3, then spontaneous breathing is not possible.
The recurrent laryngeal nerve (RLN) is a branch of the vagus nerve (cranial nerve X) that supplies all the intrinsic muscles of the larynx, with the exception of the cricothyroid muscles. There are two recurrent laryngeal nerves, right and left.

The phrenic nerve is oriented vertically as it passes in front of the anterior scalene, while the subclavian vein is oriented horizontally as it passes in front of the anterior scalene muscle. [ 4 ] The passing of the brachial plexus and the subclavian artery through the space of the anterior and middle scalene muscles constitute the scalene ...
