XII. _Of the Anatomy of the Nerves, Arteries, and Veins in general._ _What is the Structure of the Nerves?_ The Nerves are round white Bodies enclos'd in a double Membrane, communicated to them from the two _Meninges_ of the Brain: Their Office is to convey the Animal Spirits into all the Parts. _Where is the Root and first beginning of all the Nerves?_ All the Nerves take their Original from the _Medulla Oblongata_, and that of the Spine. _How is the distribution of them made thro' the whole Body?_ It is directly perform'd by Conjugations or Pairs, whereof one goes to the Right-hand, and the other to the Left: There are nine Pairs of them that proceed from the _Medulla Oblongata_ and enter into the Skull; and a Tenth that comes from the Marrow which lies between the Occipital and the first _Vertebra_ of the Neck. It {59} passeth thro' the Hole of the _Dura Mater_, thro' which the Vertebral Artery enters, to distribute its Branches into several Parts. _To what Use are the nine Pairs of Nerves appropriated, which proceed from the Root of the Brain?_ They are chiefly design'd for the Senses, and also for the Motion of their Organs, of which the Ancients discover'd only seven.
