Study Notes

Autonomic Nervous System

  • The autonomic nervous system controls involuntary activities such as blood pressure, body temperature, and sweating.

Spinal Cord

  • There are 31 spinal cord segments, numbered from top to bottom (cervical, thoracic, lumbar, sacral, and coccygeal).

Spinal Vertebrae

  • Intervertebral discs cushion the vertebrae from one another.

Creutzfeldt-Jakob Disease (CJD)

  • The key manifestation of Creutzfeldt-Jakob Disease (CJD) is rapid neurological deterioration.

Neurological Disorders

  • Bovine spongiform encephalopathy (BSE or Mad Cow Disease) is associated with variant CJD.

Guillain-Barré Syndrome (GBS)

  • The initial manifestation of Guillain-Barré Syndrome (GBS) is muscle weakness or tingling sensations in the legs.

Increasing Intracranial Pressure

  • Vital signs changes that may be indicative of increasing intracranial pressure include severe headache, vomiting, and changes in mental status.

CT Scan

  • The purpose of using IV dye in a CT scan of the brain is to enhance the visibility of structures.
  • Patients should be instructed to remove metal objects before a CT scan.

PET Scans

  • PET scans are primarily used to evaluate metabolic activity in the brain and identify areas of high glucose uptake.
