Pelvic Plexus Neurons plays an important role in the study of neurodegenerative diseases. This page provides comprehensive information about this topic, including its mechanisms, significance in disease processes, and therapeutic implications.
Pelvic Plexus Neurons are a specialized population of autonomic neurons located within the pelvic plexus, a network of nerves in the lower pelvis that controls bladder, bowel, and reproductive organ function. These neurons serve as the final common pathway for autonomic control of the lower urinary tract and represent a critical component of the enteric and pelvic nervous systems[1].
The study of pelvic plexus neurons has become increasingly important in Parkinson's Disease research, as these neurons are frequently affected by Lewy body pathology, leading to common urinary dysfunction symptoms[2].
Pelvic plexus neurons are found in:
The pelvic plexus contains several neuronal populations:
| Type | Function | Markers |
|---|---|---|
| Parasympathetic preganglionic | Activate bladder contraction | CHAT, VAChT |
| Sympathetic preganglionic | Inhibit bladder, contract sphincter | TH, DBH |
| Sensory neurons | Detect bladder fullness, pain | CGRP, TRPV1 |
| Interneurons | Coordinate reflexes | nNOS, VIP |
Key markers for pelvic plexus neurons include:
Pelvic plexus neurons coordinate micturition (urination):
Storage Phase:
Voiding Phase:
These neurons also control:
Pelvic plexus neurons are significantly affected in Parkinson's Disease:

Clinical Manifestations:
Similar to PD, Dementia with Lewy Bodies shows:
| Feature | Pelvic Plexus | Cardiac | Enteric |
|---|---|---|---|
| α-syn vulnerability | High | High | High |
| Clinical impact | Urinary dysfunction | Orthostatic hypotension | Constipation |
| Detection method | Urodynamic testing | MIBG scan | Colon transit study |
