Spinal Cord01:26

Spinal Cord

2.0K
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.

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.

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: 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: Cross-sectional Anatomy

5.0K
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.
Gray Matter and its Components
Central to the gray matter is...

Data Reporting and Recording01:24

Data Reporting and Recording

5.5K
Reporting and recording are crucial in data documentation. The timely, thorough, and accurate documentation of facts is essential when recording patient data. Failure to record findings during an assessment or interpretation of a problem will result in loss of information and make the patient document unreliable. The reader is left with general impressions if the information is not specific. A recording is documenting data of the individual's health information in a traceable, secure, and...

Area of Science:

  • Neuro-oncology
  • Spinal Cord Pathology

Background:

  • Astroblastoma is a rare cerebral tumor.
  • Spinal cord astroblastoma is exceptionally rare, with no prior reported cases.

Observation:

  • A 20-year-old woman presented with leg numbness, progressing to paraplegia and dysfunction.
  • MRI revealed an intramedullary spinal cord lesion at T1, which rapidly enlarged.
  • Histopathology confirmed astroblastoma with a Ki-67 index of 5%.

Findings:

  • The patient received radiation therapy, temozolomide (TMZ), and bevacizumab.
  • Combined treatment resulted in tumor shrinkage and significant neurological recovery.
  • The patient regained the ability to walk independently.

Implications:

  • This case suggests a potential therapeutic strategy for spinal cord astroblastoma.
  • Further research is needed to establish treatment guidelines for this rare tumor.
  • Successful management highlights the importance of multimodal therapy in aggressive spinal tumors.
