Spinal Nerves: Anatomy

11.9K
Spinal nerves are pivotal conduits in the nervous system, bridging the central nervous system (CNS) with the peripheral nervous system (PNS). These nerves enable a complex communication network between the brain, spinal cord, and the rest of the body, facilitating sensory input, motor output, and autonomic functions.
There are 31 bilateral pairs of spinal nerves, each emerging from the spinal cord through the intervertebral foramina—openings between adjacent vertebrae. These nerves are...

Spinal Nerves: Plexus II

3.1K
The plexuses of the lower body include the lumbar, sacral, and coccygeal plexuses, which innervate the abdomen, pelvis, legs, and coccygeal region. These plexuses control the transmission of sensory information and coordinate motor functions of the lower body.
The Lumbar Plexus
The lumbar plexus is situated within the lumbar region of the back and is primarily formed by the first four lumbar spinal nerves (L1 to L4). This plexus extends its branches into several nerves, including the...

Overview of Somatic Sensory Pathways01:29

Overview of Somatic Sensory Pathways

9.9K
Somatic sensory or somatosensory pathways refer to the neural pathways that carry information related to touch, pressure, pain, temperature, and proprioception from the skin, muscles, tendons, and joints to the brain. These pathways involve several stages of processing and integration of sensory information.
The somatosensory system is divided into three main pathways: the dorsal (or posterior) column-medial lemniscus, spinothalamic (or anterolateral), and spinocerebellar pathways.
The dorsal...

Major Somatic Sensory Pathways01:28

Major Somatic Sensory Pathways

3.2K
Sensory impulses related to touch, pressure, vibration, and proprioception from various body parts, such as the limbs, trunk, neck, and posterior head, travel to the cerebral cortex through the posterior column-medial lemniscus pathway. The pathway’s name derives from the two white-matter tracts that convey the impulses: the spinal cord's posterior column and the brainstem's medial lemniscus. First-order sensory neurons extend their axons into the spinal cord, forming the...

Indirect Motor Pathways01:22

Indirect Motor Pathways

3.4K
The indirect motor or extrapyramidal pathways originate in the brainstem, the lower portion of the brain that connects it to the spinal cord. They consist of several distinct tracts, each with specialized functions. The four main tracts of the indirect motor pathways are the vestibulospinal tract, the reticulospinal tract, the tectospinal tract, and the rubrospinal tract.
The vestibulospinal tract originates in the vestibular nuclei of the brainstem. The vestibular system detects changes in...

Sympathetic Pathways: Sympathetic Chain Ganglia

7.2K
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...

Summary
This summary is machine-generated.

This study reveals three pathways connecting the sacroiliac joint (SIJ) to neural structures. These findings help explain lower extremity symptoms potentially originating from SIJ dysfunction.

Area of Science:

  • Radiology
  • Anatomy
  • Pain Management

Background:

  • Clinical suspicion links sacroiliac joint (SIJ) dysfunction to lower extremity symptoms.
  • Limited scientific literature addresses this relationship.

Purpose of the Study:

  • Describe contrast extravasation patterns during SIJ arthrography and CT.
  • Identify pathways between the SIJ and adjacent neural structures.

Main Methods:

  • Fluoroscopically guided SIJ arthrography performed on 76 SIJs.
  • Post-injection imaging included radiography and CT scans.
  • Analyzed contrast extravasation patterns for neural contact.

Main Results:

  • Sixty-one percent of SIJs showed contrast extravasation.
  • Three distinct patterns demonstrated communication with neural structures.
  • Identified pathways included dorsal sacral foramina, fifth lumbar epiradicular sheath, and lumbosacral plexus.

Conclusions:

  • Three pathways exist between the SIJ and neural structures.
  • These pathways may explain neurological symptoms associated with SIJ dysfunction.
