. The anatomy of the horse; a dissection guide. Horses. DISSECTION OF THE BACK AND THORAX. 139 in the lumbar region, forming a second swelling—the lumbar enlarge- ment, from which the nerves for the supply of the hind limb are de- tached. Beyond the lumbar enlargement the cord rapidly becomes reduced in volume, and tapers to a point about the 2nd sacral seg- ment. This tapering extremity of the cord—the comes medullaris—is prolonged backwards by the filum terminale, into which its nervous structure is continued for a little distance. The Spinal Nerves of the horse number forty-two or forty-three pairs, and their number in the different regions of the vertebral column is expressed in the following formula :— CsI^isLgSsCs or c- The 1st cervical nerve leaves the canal by the antero-internal foramen of the atlas, the 2nd by the foramen in the front of the arch of the axis, and the others in succession pass out by the intervertebral foramina. In the other regions the nerves are numbered according to the vertebrse behind which they emerge; thus, the 1st dorsal nerve emerges by the intervertebral foramen behind the 1st dorsal vertebra, and so on with the others. In the cervical region the nerves pass nearly directly outwards from the cord to their points of exit from the canal. In the dorsal region, however, it will be observed that each nerve is slightly inclined back- wards from the side of the cord to the foramen by which it emerges. In the lumbar region this backward inclination of the nerves becomes. Portion of Spinai. Cord with the Roots of the Nerves {QiuCin). 1. Inferior median fissure ; 2. Superior median fissure; 3.
