The Spinal Cord01:54

The Spinal Cord

32.6K
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.

Spinal Cord

2.5K
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.

Spinal Cord: Cross-sectional Anatomy

5.9K
The cross-sectional anatomy of the spinal cord offers a detailed view of its complex structure and function within the central nervous system. At the core of the spinal cord lies the gray matter, characterized by its butterfly or "H"-shaped appearance in cross-section. This central region is enveloped by white matter, with the overall structure divided into symmetrical halves by the dorsal median sulcus and the ventral median fissure.

Spinal Cord: Gross Anatomy

6.9K
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...

Spinal Cord: Information Processing01:10

Spinal Cord: Information Processing

4.1K
The spinal cord is an integral hub for motor and sensory information that enables the brain to communicate with the peripheral nervous system (PNS). This communication consists of relaying sensory data and transmission of motor commands.
Sensory Information Processing
Sensory information processing begins at the sensory receptors located in the skin and other tissues, which detect somatic sensory stimuli such as touch, temperature, or pain. These receptors function as catalysts, initiating...

Area of Science:

  • Neurology
  • Vascular Medicine
  • Neurosurgery

Background:

  • Spinal cord infarction (SCI) is an uncommon condition with poorly understood epidemiology and risk factors.
  • Limited data exists on the prognosis for functional recovery following SCI.
  • Existing knowledge on SCI is primarily derived from studies on surgical complications and non-surgical causes.

Purpose of the Study:

  • To review the epidemiology and risk factors associated with spinal cord infarction.
  • To document the prognosis for functional recovery after spinal cord infarction.
  • To consolidate current clinical information on SCI to guide future research.

Main Methods:

  • Literature review of existing studies on spinal cord infarction.
  • Analysis of reported cases of SCI, including surgical and non-surgical etiologies.
  • Synthesis of information on spinal cord vascularization and common causes of SCI.

Main Results:

  • Spinal cord infarction is infrequently studied, leading to knowledge gaps in epidemiology and risk factors.
  • Functional recovery prognosis after SCI remains inadequately documented.
  • Recognized causes of SCI include aortic pathology, systemic hypoperfusion, and embolic events.

Conclusions:

  • Further research is needed to elucidate the epidemiology and risk factors of spinal cord infarction.
  • Improved understanding of SCI pathophysiology and causes is essential for developing effective treatments.
  • Knowledge of spinal cord blood supply is vital for future clinical trials on neuroprotection and perioperative strategies to mitigate SCI-related disability.
