DISSECTION OF THE HEAD AND NECK

(ca) Middle cervical ganglion (ganglion cervicale medium). 



Does it rest on the A. thyreoidea inferior? 



(cb) Inferior cervical ganglion (ganglion cervicale inferius). 



Look for it in the depression between the transverse 

 process of the seventh cervical vertebra and the neck of 

 the first rib. 



(cc) Superior cardiac nerve (N. cardiacus superior). 



(cd) Middle cardiac nerve (N. cardiacus medius). 



(ce) Inferior cardiac nerve (N. cardiacus inferior). 



(cf) Subclavian loop (ansa subclavia [ Vieussenii] ) . 

 (eg) Subclavian plexus (plexus subclavius).

 kima glottidis 



Cross-section through the neck at the level of the rima glottidis and through the body of the fifth 

 cervical vertebra. Cut surface below the plane of section. (After Toldt, Anat. Atlas, Wien, 1900, 

 2Aufl.,p. 608, Fig. 984.) 



Viscera. 



(a) Summit of pleura (cupula pleurae). 



How far above the level of the sternal extremity of the clavicle 

 does it extend into the neck? Which is higher, the left or the 

 right? Is there a M. scalenus minimus or tensor of the cupula 

 pleurae present? What is Sibson's fascia? What structures 

 come into contact with the cervical pleura on the right side? 

 What on the left? 



Note the fibrous expansions helping to support and fix the 

 cupula (cf. Poirier et Charpy, t. iv., Figs. 250-252) : 



(1) From the apex of the dome to the fourth to seventh cer- 

 vical vertebrae.
