DR. LEE ON THE GANGLIA AND NERVES OF THE HEART. 
Explanation of the Plates. 
PLATE III. 
Exhibits the trunk and branches of the coronary arteries, and the ganglia and 
nerves distributed over the anterior surface of the ventricles of the young Heifer’s 
heart; the serous membrane and cardiac fascia having been wholly removed. 
PLATE IV. 
Represents the posterior surface of the same heart covered with ganglia and 
nerves, from the base to the apex. 
PLATE V. 
Represents the aorta and the anterior surface of a human heart which was hyper- 
trophied, and weighed four pounds. The trunk and some of the branches of the left 
coronary artery were ossified. The pulmonary artery has been cut away close to the 
right ventricle. A portion of the wall of the right ventricle has been removed to 
expose the cavity and the septum between the ventricles. The serous membrane 
has been reflected off from the cardiac fascia, a small portion only of which has been 
left covering the ventricle. 
a. The arch of the aorta. 
h. The origin of the pulmonary artery, which has been completely removed. 
c. The anterior surface of the left ventricle. 
d. The anterior surface of the right ventricle. 
e. The great ganglionic plexus of nerves into which branches from the par 
vagum, recurrent and sympathetic nerves of both sides enter, and from 
which the principal cardiac nerves take their origin. 
f. The par vagum of the left side. 
g. The trunk of the left coronary artery ossified and completely surrounded 
with ganglia and nerves, which are distributed over the whole surface 
of the ventricle to the apex. 
h. The serous membrane reflected off from the cardiac fascia, a small por- 
tion only of which is left covering the ganglia and nerves near the apex. 
i. The cardiac fascia.
