(2) Peripheral motor {vasomotor) impotence from functional disturb-ance in the motor (vasomotor) innervation tracts of the corpora cavernosa—i. e., in the erigens nerve—of the smooth musculature of the spermatic duct,the seminal vesicles and the prostate gland, also of the bulbi and ischio-cavernosi muscles. (3) Sympathetic (janglion impotence caused by a disturbance in functionof the sympathetic ganglia of the floor of the pelvis which control the reflexesof erection and seminal discharge. 990 SEXUAL NEURASTHENIA. (4) Spinal ganglion impotence from disturbance of function of theejaculatory center situated in the lowest portion of the spinal cord (conns). (5) Spinal sensory conduction impotence fromfunctional disturbance in the spinal portion ofthe ascending genital centripetal tracts. (6) Spinal motor conduction im^potence fromfunctional disturbance of the spinal portion ofthe descending genital centrifugal tracts. (7) Cerebral sensory and (8) Cerehral motor conduction impotence dueto analogous functional disturbances in the intra-cerebral portions of the corresponding genitaltracts. (9) Cortical sensory and (10) Cortical motor impotence from disturb-ances of function in the cerebro-cortical termina-tions of the affected tracts, (11) Intercentral impotence caused by dis-turbance in the function of the communicatingtracts of the sensory and motor cortical termi-nations. (12) Transcortical ^ impotence through func-tional disturbance in the cortical centers beyo
