II. SCHEMATIC REPRESENTATION OF SOME POINTS IN THE PHYSIOLOGY AND PATHOLOGY OFTHE SPINAL CORD AND PERIPHERAL 28. Diagram to illustrate the mechanism of the bladder reflex B represents the bladder. S C rep-resents the reflex centre, with its motorand sensory neurons, for the sphincter ofthe bladder, which is excited to action byurine in the neck of the bladder or in theprostatic urethra. DC represents there-flex centre, with its motor and sensoryneurons, for the detrusor of the bladder,which is excited to action by the disten-tion of the walls of the bladder. Thesetwo reflexes are antagonistic and the sen-sory surface irritated being much largerin the latter (D C), than in the former (SC), reflex, the detrusor reflex will eventuallyoverpower the sphincter reflex under nor-mal conditions. S T represents the sensorytract connecting the bladder with thebrain, by means of which the individualis informed as to the degree of fulness ofthe bladder. M T represents the mot
