at greater sacro-sciatic foramen into anterior and posterior 

 trunks. Branches from the ANTERIOR trunk are : Vesica'liS 

 SUpo'riori part of foetal-hypogastric that remains pervious, to 

 fundus of bladder, and vas deferens. Vesica'liS me'dia! base of 

 bladder and vesiculae seminales. Vesica'liS infs'rior : base blad- 

 der, prostate, and vesiculae seminales. HsnorrJl.ida'liS me'di} I 

 rectum, anas, with haemorrhoidal branch of inferior mesen- 

 teric and internal pudic. (Uterine: to neck, and ascends to 

 fundus, giving branch to ovary and tube, etc. Vaginal! cor- 

 responds to inferior vesicle, supplying vagina, urethra, etc.) 

 Cbturato'ria : forwards to superior border obturator foramen, 

 escaping there, dividing into an internal (curving round inner 

 border foramen, supplying adjacent muscles, etc., anas, with 

 external branch and internal circumflex) and external branch 

 (round outer margin foramen supplying adjacent muscles). 

 The branches inside the pelvis are iliac, vesical and^utzc; the 

 latter anas, with epigastric. Sometimes rises from epigastric, 

 then liable to be wounded in operation for hernia. Plldi'd 

 intsr'na; terminal branch; supplies external generative organs ; 

 out of pelvis beneath pyriformis (great sacro-sciatic foramen), 

 crosses ischic spine, re-enters pelvis, through lesser sacro- 

 sciatic foramen, ascends ischic ramus up to pubes. Htzmor- 

 rhoida'les znferio'res, 2 or 3 to rectum, etc. Superficia' Us 

 ferinai'i, to scrotum and perinaeum. Transver'sa, germce'l. 

 A. corpo'ris bulbo'si, to bulb and Cowper's gland. A. corpo'ris 

 caverndsi, terminal branch running forwards in this struc- 

 ture. Dorsa'lis pe'nis, forwards to glans. Sciat'ica: terminal 

 branch (see lower extremity.) Branches from the POSTERIOR 

 trunk are: Glutffi'a SUpe'rior: (see lower extremity.) Hifl-lumba'lis \ 

 divides at upper part iliac fossa into lumbar (to psoas and 

 quaclratus muscles, branches to spinal canal) and iliac 

 branch (to iliacus internus, anas, with gluteal, epigastric, 

 etc.) Sacra'leS laterals: : (2) superior , enters ist or 2d sacral 

 foramen, anas, wuh fellows and middle sacral ; inferior, de- 

 scends on sacrum, anas, over coccyx with middle sacral and 

 opposite fellow. 



ILI'ACA E2TEBUA : from bifurcation common iliac to femoral 

 arch. Li.ie drawn from left of umbili'cus to a point on Pou- 

 part's ligament midway between pubes and anterior superior 

 spinal process of ilium, indicates its course. Epigas'tlica! 

 few lines above Poupart's, up- and inwards to umbili'cus, 

 there anas, with internal mammary and inferior intercostal.
