A MANUAL OF ANATOMY 



The superior surface is markedly convex in its right portion, and 

 accurately adapts itself to the concavity of the diaphragm with 

 which it is in contact. To the left of this convex part there is a 

 depression, called the impressio cardica, produced by the heart 

 with the intervention of the diaphragm. To the left of this im- 

 pression the superior surface again becomes convex, and adapts 

 itself to the concavity of the left half of the diaphragm. The 

 superior surface is separated from the posterior, anterior, and right 

 lateral surfaces by round, somewhat indistinct, borders.

The anterior surface looks forwards and is triangular. The 

 apex is directed towards the left extremity of the liver, whilst 

 the base is towards the right extremity. One side of the 

 triangle corresponds to the anterior border, the other side being 

 formed by the round border which separates the anterior from 

 the superior surface. The anterior surface is mainly in contact 

 with the diaphragm and the right and left costal margins, but at 

 the middle line it is in relation with the ensiform process, and, for 

 about 2 inches below that process, it is in contact with the anterior 

 abdominal wall. The superior and anterior surfaces are divided 

 into two lateral parts by the falciform ligament, the part to the 

 right of this ligament being called the right lobe, and the part to 

 the left the left lobe. The right lobe forms about four-fifths of the 

 entire supero-anterior surface in the adult, but in early life the two 

 lobes are very nearly of equal size. 



The inferior surface looks downwards with an inclination to 

 the left. It is divided into two parts, right and left, by the 

 umbilical fissure. The part to the left of this fissure represents 

 a portion of the left lobe. It lies in front of the cardiac orifice
