500 LABORATORY MANUAL OF HUMAN ANATOMY 



(a) Serous coat (tunica serosa). 



(b) Muscular coat (tunica muscularis). 



(ba) Longitudinal layer (stratum longitudinale) . 



(bb) Pyloric ligaments (Ligg. pylori}, 

 (be) Circular layer (stratum circular e}. 



(bd) Sphincter muscle of pylorus (M. sphincter pylori). 



(be) Oblique fibres (ftbrae obliquae). 



(c) Pyloric valve (valvula pylori). 



(d) Submucous layer (tela submucosa). 



(e) Mucous coat (tunica mucosa). Can you make out the lamina muscu- 



laris mucosae? 



(ea) Gastric areas (areae gastricae). 



(eb) Mucous folds (plicae mucosae). 



(ec) Gastric pits (foveolae gastricae). 



(ed) Gastric lymph-nodules (noduli lymphatici gastrici). 



With a loop (lens) look at the openings of the gastric glands. 



(a) [Proper] gastric glands (glandulae gastricae [propriae]). 



(b) Pyloric glands (glandulae pyloricae). 



There are only a few true " cardiac 7 ' glands in the human 

 stomach. (Cf. Bensley, E. R., " The Cardiac Glands of Mam- 

 mals, " Am. J. Anat., Bait., 1902, vol. ii. p. 105.) 



The mixed secretion of the glands is called the gastric juice 

 (succus gastricus). 



Abdominal Part of Sympathetic System (Pars abdominalis S. sym- 

 pathici). (Vide Toldt, Fig. 1332.) 



Dissect out carefully the sympathetic nerves and ganglia sit- 

 uated about the coeliac artery. Determine the course of the dif- 

 ferent plexuses which surround the arteries given off from the 

 main trunk. 



(a) Coeliac plexus (plexus coeliacus). 



(b) Coeliac ganglia (ganglia coeliaca). 



(c) Phrenic plexus (plexus phrenicus). 



(ca) Phrenic ganglia (ganglia phrenica). 



(d) Hepatic plexus (plexus hepaticus). 



(e) Splenic plexus (plexus lienalis). 



(f) Renal plexus (plexus renalis). 



(g) Suprarenal plexus (plexus suprarenalis) . 



(h) Superior gastric plexus (plexus gastricus superior), 

 (i) Inferior gastric plexus (plexus gastricus inferior). 



The two latter have been destroyed in the removal and dissection 

 of the stomach. Examine models to determine their exact position 

 and the arteries that they accompany. 



Dissect carefully the abdominal aorta and study 



(j) Abdominal aortic plexus (plexus aorticus abdominalis). It has 

 already been examined.
