You will discover twelve pairs of cranial nerves which arise from your brain, and 31 pairs of spinal nerves which lengthen from your spinal cord.

Lymphatic vessels empty into greater lymphatic trunks, which unite to sort one of the two most important gathering ducts; the thoracic duct and the proper lymphatic duct. The thoracic duct starts within the cisterna chyli, accumulating lymph within the still left facet of head, neck and thorax, still left higher limb, abdomen and both of those reduce limbs and draining it into the still left venous angle (junction with the still left inner jugular and left subclavian veins).
