external urethral sphincter morphology-ultrastructure-innervation investigational techniques
summary
- Innervation of the external urethral sphincter (e. u. s.) is very complex both
- from the anatomical and functional point of view. Therefore, they are some
- limitations of the investigational techni±ues employed. The abdomina]
- approach to the pudendal canal could easy lead to the omitting of the nerves
- ramifying very high from the pudendal trunk, or those ramifying directly from
- the ventral roots of the spinal cord. The interpretation of the morphological
- studies of the e. u. s. region is impossible without a precise investigations of
- the structures found in the neighbuorhood of this muscle and without a precise
- settlement of the place where terminal ramifications of the nerve branch to the
- e. u. s. are entering the muscle.
- Proper material selection for both anatomical and morphological studies is
- very important. Foetal material is the most appropriate for the anatomical
- studies of this subject. For the immunohistochemical studies material most
- similar to the human (e.g. pig) should be used, since some pathological states
- spinal cord injuries, neoplasms
