and recurrent laryngeal nerves, and with the upper cardiac 

 nerve from the superior ganglion. 



Middle or great cardiac nerve : on the right side passes in 

 front or behind subclavian artery to the front of the trachea, 

 and joins the deep cardiac plexus. Communicates in the neck 

 with the upper cardiac and recurrent laryngeal nerves. On 

 the left side it lies between the left carotid and left subclavian 

 arteries, and joins the deep cardiac plexus. 



3. The LOWER CERVICAL GANGLION lies between the 

 transverse process of the yth cervical and the neck of the 

 ist rib, behind the vertebral artery, internal to the superior 

 intercostal artery. 

 Branches : 



Connecting : to the 7th and 8th cervical nerves. 

 Lower cardiac nerve : passes behind the subclavian artery, 

 joins recurrent laryngeal, and enters the deep cardiac plexus. 

 Branches to vessels : branches are given to form a plexus 

 round the vertebral artery. 



The THORACIC PART of the gangliated cord lies by the side 

 of the vertebrae in a line corresponding to the heads of the 

 ribs. The ganglia are usually twelve in number, and each com- 

 municates with the corresponding intercostal nerve. 



Branches of the upper 6 ganglia are given off to the thoracic 

 aorta, vertebras, ligaments, and from the third and fourth to 

 the posterior pulmonary plexus. 

 Branches from the lower 6 ganglia : 



The great splanchnic nerve : formed by the union of 

 branches from the 6th, yth, 8th, gth, and loth ganglia. It 

 passes inwards over the bodies of the vertebras, perforates the 

 crus of the diaphragm, and ends in the semilunar ganglion. 



The small splanchnic nerve comes from the loth and nth 

 ganglia, passes with the great splanchnic nerve, and ends in 

 the solar plexus. 



The smallest splanchnic nerve comes from the i2th 

 ganglion. It pierces the crus of the diaphragm, and ends in 

 the renal plexus, and partly in the coeliac plexus. 



The LUMBAR PART of the gangliated cord lies nearer the 

 middle line than the thoracic on the bodies of the vertebrae. 

 Each ganglion communicates with the anterior division of 

 a lumbar nerve by branches which pass under fibrous arches 

 of psoas. The ganglia give off branches to the aorta, and 

 other branches to form the hypogastric plexus. 



The SACRAL PART of the gangliated cord lies to the inner 

 side of the anterior sacral foramina, and is united with its 

 opposite fellow at the lower end of the sacrum by a cord, in
