What Are the Parts contain'd in the Epigastrium, and what Place do they possess therein?
The Parts contain'd in the Epigastrium are the Liver, the Spleen, the Stomach, and the Pancreas or Sweet-bread, which lies underneath: The Stomach takes up the middle before, the Liver being plac'd on the Right side, and the Spleen on the Left; so that these two sides of the Epigastrick Region, are call'd the Right and Left Hypochondria.
What Parts are there contain'd in the Umbilical Region, and what is their situation?
They are the most part of the thin Intestines or small Guts, viz. the Duodenum, the Jejunum, and the Ileon, which have their Residence in the middle, where they are encircled with a Portion of the two great Guts, Cæcum and Colon, that take possession of the Sides, otherwise call'd the Flanks. The Reins or Kidneys are also in this Place, above, and somewhat backward.
What Parts are there contain'd in the Hypogastrium, and of what Place are they possest?
The greater part of the thick-Guts, Cœcum, and Colon, are enclos'd therein, with the entire Rectum; there is also a Portion of the Ileon, which hides it self in the sides of the Ilia, or Hip-Bones: In the middle under the Os Pubis, the Bladder is situated on the Gut Rectum in Men, and the Matrix in Women lies between the Rectum and Bladder.
After what manner is the opening of a Corps or dead Body perform'd at a publick Dissection?
It is begun with a Crucial Incision in the Skin from underneath the Throat downward, traversing from one side to another in the Umbilical Region; then this Skin is pull'd off at the four Corners, and the Panicula Adiposa is immediately discover'd: Under this Fat lies a Fleshy Membrane, call'd Membrana Carnosa; and after that, the common Membrane of all the Muscles of the lower Belly. Thus we have taken a View of what Anatomists commonly term the five Teguments, that is to say, the Epiderma or Scarf-Skin, the Derma or true Skin, the Panicula Adiposa, the Panicula Carnosa or Membranus Carnosa, and the common Membrane of the Muscles.
The five Teguments being remov'd, we meet with as many Muscles on each side, viz. the descending Oblique, the ascending Oblique, the Transverse, the streight, and the Pyramidal, by the means whereof the Belly is extended and contracted. Afterwards appears a Membrane nam'd Peritonæum, which contains all the Bowels, and covers the whole lower Belly, being strongly fasten'd to the first and third Vertebra's of the Back. The Fat skinny Net which lies immediately under the Peritonæum, is call'd Epiploon and Omentum, or the Caul; it floats over the Bowels, keeping them in a continual Suppleness necessary for their Functions, maintains the Heat of the Stomach, and contributes to Digestion.
