Summary
Intraspinal anatomical variations of nerve roots, particularly in the sacral region, were identified. These variations may influence the clinical presentation of radiculopathy.
Area of Science:
- Anatomy
- Neurology
Background:
- Nerve root variations can impact neurological function.
- Understanding intraspinal anatomy is crucial for diagnosing conditions like radiculopathy.
Purpose of the Study:
- To identify and describe intraspinal anatomical variations of nerve roots.
- To explore the potential role of these variations in radiculopathy.
Main Methods:
- Anatomical study of 33 human cadavers (25 male, 8 female).
- Histological examination of excised intradural rami communicantes.
- Classification of plexus formation types.
Main Results:
- Plexus formation variations observed in 27.3% of cases.
- Intradural variations were found in all lumbosacral plexuses studied.
- Higher incidence of variations noted between sacral roots.
Conclusions:
- Identified novel intraspinal intradural nerve root variations.
- These variations, especially in the sacral region, may influence clinical symptoms.
- Incidence of variations correlates with plexus type.

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...

01:54The Spinal Cord
32.5K
The spinal cord is the body’s major nerve tract of the central nervous system, communicating afferent sensory information from the periphery to the brain and efferent motor information from the brain to the body. The human spinal cord extends from the hole at the base of the skull, or foramen magnum, to the level of the first or second lumbar vertebra.

The spinal cord resides within the protective confines of the vertebral column. It is the main pathway for information traveling between the brain and the body. It plays a fundamental role in nearly all bodily functions, from simple reflexes to complex motor movements. The spinal cord begins at the medulla oblongata at the base of the brainstem and extends downward, terminating at the conus medullaris near the first and second lumbar vertebrae. The spinal cord's length in adults is...

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...

Nerve plexuses are networks of interlacing nerves that serve as communication hubs to distribute and organize nerve action across various body regions. The nerve plexuses are organized into the cervical plexus located in the neck region, brachial plexus in the shoulder area, lumbar plexus found in the lower back, sacral plexus situated in the pelvis, and coccygeal plexus located in the coccygeal region.

The spinal cord, a critical component of the central nervous system, extends from the base of the brainstem to the lumbar region of the vertebral column. It is essential for maintaining physical stability and facilitating communication between the brain and peripheral parts of the body.
