(_e_) A transverse lesion of the cord at the level of the last cervical and first dorsal nerves—_i.e._ in the lower part of the cervical enlargement—gives rise to typical paraplegia with a sensory limit-line at or just below the clavicle, but also with some very peculiar symptoms superadded. These characteristic symptoms are in the upper extremities, and consist of paralysis and anæsthesia in the range of distribution of the ulnar nerves. In the arms the anæsthesia will be found along the lower ulnar aspect of the forearm, the ulnar part of the hands, the whole of the little fingers, and one half of the annuli. There will be paralysis (and in some cases atrophy with De R.) affecting the flexor carpi ulnaris, the hypothenar eminence, the interossei, and the ulnar half of the thenar group of muscles, producing in most cases a special deformity of the hand known as claw-hand or main-en-griffe. Another important symptom of a transverse lesion in this location is complete paralysis of all the intercostal and abdominal muscles, rendering respiration diaphragmatic and making coughing and expectoration impossible. The breathing is abdominal in type, and asphyxia is constantly impending. (_f_) A transverse lesion of the upper part of the cervical enlargement, below the origin of the fourth cervical nerve, gives rise to symptoms {76} designated as cervical or total paraplegia. The lower extremities and trunk are as in (_d_) and (_e_), but besides both arms are completely paralyzed and anæsthetic. The limit of anæsthesia usually extends along the clavicles to the acromion processes, or a little below, near the deltoid insertions. All reflexes caudad of this line are vastly increased, either with tonic or clonic contractions. In some cases of pressure upon the cervical cord by tumors, caries of vertebræ, etc. the tetanoid or spastic state of the extremities (the lower more especially) may precede paralysis for a long time; as the compression increases paralysis becomes more and more marked, while the reflexes remain high. This constitutes the clinical group we described in 1873 as tetanoid pseudo-paraplegia. (_g_) Transverse lesions of the spinal cord from the decussation of the pyramids to the fourth cervical nerve are very rare, and usually of traumatic origin. They produce complete paralysis of the entire body, and also of the diaphragm (third and fourth cervical nerves), thus causing death by apnœa in a very short time. (_h_) In ascending paralysis (Landry) the above symptom-groups, excepting (_a_), (_b_), are met with at successive stages of the disease, often by almost daily accession, until finally respiration ceases.
