=Transverse section of the cervical lateral columns= causes motor paralysis of the lateral walls of the chest (respiratory tract). If the section is made in the dorsal or lumbar region it is the same as lesion of the superior columns. Among =reflex centres= in the cord the following may be named: The =Respiratory Tract= in the cervical lateral columns just referred to. A =Glycogenic Centre= in the anterior cervical section between the bulb and the fourth cervical nerve. =Centres which Dilate the Pupil= between the fifth cervical and the sixth dorsal nerve. =Cardiac Accelerator Centres= between the three last cervical and the five first dorsal nerves. =Vaso-Motor Sudoriparous Centres= in the central gray matter. =Centre for Anal Sphincter= between the sixth and seventh dorsal nerves. =Centre for Vesical Sphincter= between the third and fifth lumbar nerves. =Genital Centre=, opposite the first lumbar nerve. =Vaso-motor and Trophic Centres= are found in the inferior horns of gray matter, and their degeneration causes progressive muscular atrophy. The =Muscular Sense Tract= is located near the surface of the superior columns, so that a certain amount of incoördination and unsteadiness of progression follows its destruction. The =Deeper Part of the Superior Columns= and the =Column of Goll= which bounds the superior median fissure control muscular sense and coördination, and their disease (posterior lateral sclerosis) entails locomotor ataxy.
