How is the Humane Body divided before it is dissected, in order to Anatomical Demonstration?

Some Anatomists distinguish it into Similar and Dissimilar Parts, appropriating the former Denomination to all the simple Parts of the Body taken separately, as a Bone, a Vein, a Nerve, &c. but they attribute the Name of Dissimilar to all those Members that are compos'd of many Similar or Simple Parts together; such are the Arms, Legs, Eyes, &c. wherein are contain'd all at once, Bones, Veins, Nerves, and other parts.

Others divide it into containing and contained Parts, the former enclosing the others, as the Skull includes the Brain, and the Breast the Lungs; whereas the contained Parts are shut up within others; as the Entrails within the Belly, the Brain within the Skull, &c.

Others again divide the whole Body into Spermatick and Sanguineous Parts; the former being those which are made at the time of Formation; and the latter all those that are grown afterward by the Nourishment of the Blood.

Are there not also other Methods of dividing the Humane Body?

Yes: Many Persons consider it as a Contexture of Bones, Flesh, Vessels and Entrails, which they explain in four several Treatises, whereof the first is call'd Osteology, for the Bones; the second Myology, for the Muscles; the third Angiology, for the Veins, Arteries and Nerves, which are the Vessels; and the fourth Splanchnology, for the Entrails.

But lastly, the most clear and perspicuous of all the Divisions of the Body of Man, is that which compares it to a Tree, whereof the Trunk is the Body, and the Branches are the Arms and Legs. The Body is divided into three Venters, or great Cavities, viz. the Upper, the Middle, and the Lower, which are the Head, the Breast, and the lower Belly. The Arms are distributed into the Arms properly so called, the Elbow and Hands; and the Legs in like manner into Thighs, Shanks, and Feet: The Hands being also subdivided into the Carpus or Wrist, Metacarpium or Back of the Hand, and the Fingers; as the Feet into the Tarsus, Metatarsus, and Toes. This vision is at present follow'd in the Anatomical Schools.
