TEE ARTERIES. 



reaches the anterior fissure of the spleen, in turning round the cardiac extremity 

 of the stomach, passes along the entire length of that fissure, and leaves it only 

 near the point of the organ to throw itself into the great omentum, where it is 

 named the left gastro-omeatal artery (or gastro-epiploica sinistra). 



The splenic artery gives off, during its course, very numerous collateral 

 oranches. These are : 



(1) External or splenic ramifications, which immediately enter the substance 

 of the spleen (Fig. 365).

(2) Internal or gastric ramifications, also called the short vessels (vasa hrevia) 

 m Man, which are comprised between the two layers of the gastro-splenic 

 omentum, and go to the great curvature of the stomach, where they nearly 

 always divide into two branches — one which ramifies on the anterior wall of the
