![]() The phrenic nerves run anteriorly to the subclavian arteries, but posterior to the subclavian veins. ![]() These are responsible for motor and sensory supply to the diaphragm, as well as for sympathetic output. The C3, C4, and C5 roots contribute to form the phrenic nerves. This function is necessary for proper speech and swallowing. All of the muscles supplied by branches of the ansa cervicalis, along with the thyrohyoid, are infrahyoid muscles, and therefore serve to depress the hyoid bone. #Human neck diagrams software#This structure gives rise to the nerves to the sternohyoid, sternothyroid, and superior and inferior bellies of the omohyoid muscles. 3D4Medical is an award-winning 3D technology company that specializes in medical, educational and health & fitness software for student/patient education. ![]() More specifically, one end of the loop, the superior root, is derived from C1 (and possibly C2, depending on the literature), while the other, the inferior root, comes from C2 and C3. The ansa cervicalis (“handle of the neck” in Latin), is a loop of nerves that lies superficial to the internal jugular vein, composed of the C1 to C3 nerves. Anatomically, these nerves travel closely to the hypoglossal nerve (CN XII).
