Sympathetic Pathways: Sympathetic Chain Ganglia01:20

Sympathetic Pathways: Sympathetic Chain Ganglia

7.3K
The sympathetic chain ganglia, also known as the sympathetic trunk ganglia or paravertebral ganglia, are a series of ganglia located bilaterally on either side of the spinal column. These ganglia serve as relay stations for the sympathetic nervous system. Preganglionic neurons originating in the spinal cord project their axons to the sympathetic chain ganglia. Within the ganglia, these preganglionic fibers synapse with postganglionic neurons.The postganglionic neurons of the sympathetic trunk...

Sympathetic Pathways: Collateral Ganglia and Adrenal Medulla

3.3K
The sympathetic pathways of the collateral ganglia and adrenal medulla serve unique but interconnected roles in the sympathetic response.
Collateral Ganglia
Sympathetic preganglionic axons reach the collateral ganglia along the route of splanchnic nerves. These nerves bypass the sympathetic trunk and communicate with sympathetic postganglionic neurons housed in the prevertebral ganglia. These ganglia supply the organs of the abdominopelvic cavity.
The greater splanchnic nerve, formed by the...

Peripheral Nervous System: Ganglia and Nerves

7.2K
The Peripheral Nervous System (PNS) is a crucial component of the body's neural network, extending beyond the central nervous system (CNS) to bridge the gap between the CNS and the external environment. It encompasses nerves, ganglia, and sensory receptors.
Nerves
The nerve is a bundle of axons that serves as the communication highway in the PNS. Each nerve is ensheathed in a protective layer of connective tissue called the epineurium. This outermost layer safeguards the nerve and supports the...

Area of Science:

  • Neurology
  • Pathology
  • Neurosurgery

Background:

  • Ectopic ganglionic tissue in the cauda equina is a rare finding.
  • It is typically associated with spinal dysraphism.
  • This condition can be misdiagnosed as a cauda equina neoplasm.

Observation:

  • A 29-year-old woman presented with back and leg pain, and urinary incontinence.
  • Imaging revealed an enhancing mass in the cauda equina at the L1-2 interspace.
  • Biopsy confirmed a 1.3 cm focus of ectopic ganglionic tissue.

Findings:

  • This is the first reported case of ectopic ganglionic tissue in the cauda equina without spinal dysraphism.
  • The patient's presentation mimicked a neoplastic lesion.
  • Histopathological analysis confirmed the diagnosis.

Implications:

  • Ectopic ganglionic tissue should be considered in the differential diagnosis of cauda equina space-occupying lesions.
  • This finding expands the understanding of spinal cord malformations.
  • Accurate diagnosis is crucial for appropriate patient management and surgical planning.
