Reflect the flap outwards and expose the superficialfascia. Over the Perinaeum this consists of two layers, ofwhich the superficial is now seen. The following structures in their order, from beforebackwards, are also displayed. 152 A MANUAL OF DISSECTIONS. 1. Cataneons arteries from— «.

The Gluteal passing through the Gluteusmaximus muscle. 2. At the back of the Ischio-rectal fossa, an offset of THE PUDIC ARTERY. 153 the Inferior Hemorrhoidal branch of the Pudicnerve, turning round the Gluteus muscle ; and 3. Branches of the Small Sciatic nerve external to it, and having a similar distribution. 4. The Hemorrhoidal branch of the fourth Sacral nerve in the angle between the Gluteus maximus andExternal Sphincter ani muscles. 5. The Coccygeal nerve close to the Coccyx. 6.
