The Second Figure
Shews the Basis of a Sheeps Brain taken out of the Skull, and the Roots of the Vessels cut off, where all the Arteries, by Ink being injected into one of the Carotides, are made black and more conspicuous.
- AA. Two Hemispheres of the Brain without Lobes, different from that in a Man.
- BB. The lateral portions of the Cerebel.
- CCC. The oblong Marrow.
- DD. The olfactory or smelling Nerves cut off nigh to the mammillary Processes, that their Cavities may appear.
- E. The coalition or joyning together of the Optick Nerves.
- FF. The motory Nerves of the Eyes, or the third pair.
- GG. The Pathetick Nerves, or fourth pair.
- HH. The fifth pair: the Trunk of which Nerve is presently divided into two Branches.
- II. The sixth pair.
- KK. kk. The seventh pair, or the hearing Nerves, on either side of which are two Processes.
- LL. The eighth or wandring pair, the origine of which is made up of very many Fibres seeming to grow together.
- MM. A Nerve coming out of the spinal Marrow to the beginning of the wandring pair.
- NN. The ninth pair, consisting also of divers Fibres arising distinctly, which afterwards grow together into one Trunk.
- OO. The tenth pair tending downwards.
- PP. The Trunk of the Carotidick Artery cut off, where it is divided into the anterior and posterior Branch.
- QQ. The inosculation of the anterior Branches.
- R. The posterior Branches of the Carotides united, and meeting with the Vertebral Trunk.
- SSS. The Vertebral Artery ascending with a triple Branch.
- TT. Where the Carotides meet the Vertebral, and on either side many Arteries ascend to the Choroeidan infolding.
- V. The coalition or joyning together of the Vertebral Branches into the same Trunk.
- W. The Tunnel.
