The Spinal Cord01:54

The Spinal Cord

31.9K
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.

Nephrotic Syndrome I : Introduction

685
Nephrotic Syndrome is a chronic kidney disorder defined by clinical findings such as severe proteinuria, hypoalbuminemia, hyperlipidemia, and edema. These symptoms result from damage to the glomeruli, the kidney’s filtering units, increasing their permeability to proteins.Definition and Meaning:Proteinuria, defined as the loss of more than 3.5 grams of protein per day in adults, is a crucial feature of nephrotic syndrome. This condition is often accompanied by edema, the accumulation of...

Spinal Cord: Information Processing01:10

Spinal Cord: Information Processing

3.6K
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...

Spinal Cord: Cross-sectional Anatomy

4.9K
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

5.9K
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

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.

Summary
This summary is machine-generated.

Spinal cord infarction, though rare, requires early recognition due to potential aortic conditions. Anterior spinal artery syndrome is common, causing bilateral weakness and sensory loss, but other forms of spinal ischemia exist.

Area of Science:

  • Neurology
  • Vascular Medicine
  • Neurosurgery

Background:

  • Spinal cord infarction is a rare cerebrovascular event compared to cerebral stroke.
  • Early diagnosis is crucial as it can indicate underlying serious aortic diseases.

Purpose of the Study:

  • To summarize the clinical presentations and classifications of spinal cord infarction.
  • To highlight the importance of recognizing spinal ischemia for timely management of associated vascular pathologies.

Main Methods:

  • Review of clinical literature on spinal cord infarction.
  • Analysis of diagnostic criteria and presenting symptoms.
  • Classification of different etiological and anatomical subtypes.

Main Results:

  • Anterior spinal artery syndrome is the most frequent type, characterized by paraparesis, impaired spinothalamic sensation, and preserved deep sensation.
  • Posterior spinal infarcts may affect lemniscal sensation while sparing spinothalamic pathways.
  • Other variants include unilateral, central, transverse infarcts, spinal transient ischemic attacks, venous infarction, fibrocartilaginous embolism, and decompression sickness.

Conclusions:

  • Spinal cord infarction presents with diverse neurological deficits depending on the affected spinal cord region and vascular supply.
  • Recognition of spinal ischemia is vital for identifying and managing potentially life-threatening conditions like aortic disease.
