terminal artery
5.It appeared between the supinator and the abductor pollicis longus and descended in the posterior compartment of the forearm between the superficial and deep layers of muscles. Its terminal branches curved anastomosed with the dorsal branch of anterior interosseous artery 2.5±0.5cm above styloid process of ulna. This anastomosis branch had its high occurrences(96.7%) and 7-12 cutaneous branches arose from posterior interosseous artery to supply blood for the skin of dorsal forearm.
7.CONCLUSION: The pathway net of vascular nerve terminal receptor in mainly composed of sympathetic ganglion, postganglionic fiber and parasympathetic nerve, the ascending pathway net can reach to spinal ganglia and spine, and the descending pathway net can reach to sarcolemma of sacral spinal muscle, tracheal intima and adventitia, myocardial intima and adventitia, renal glomerulus, ansa of intracutaneous blood capillary and artery walls.
