• Femoral nerve aka

  Anterocrural nerve
• Sciatic nerve entrapment:

  • Piriformis
  • Fat wallet syndrome
  • Injection injury
• Collection of cell OUTSIDE

  Ganglia
• Ganglia INSIDE

  Nuclei
• Supplies the visceral organs and glands (involuntary)

  Autonomic nervous system
• Supplies the voluntary parts

  Somatic Nervous System
• Skeletal muscle, skin, and joints

  SNS
• Supplies heart, sweat and salivary glands

  ANS
• Impaired lacrimation

  Terigopalatene
• Dorsal root does not have

  Ventral root
• 1st order in pain

  Dorsal root ganglion
• 2nd order in pain

  Substantia Gelatinosa
• 3rd order pain

  Ventral posterolateral nucleus of tahalamus
• ROUND cells with 1 PROCESS LEAVING the body

  DRG
• Erb palsy/ waiter's tip affected nerve

  UPPER: C5-C6 brachial plexus
• Klumpke affects

  lower brachial plexus
• Copies the effect of sympathetic response

  Sympathomimetic
• Contra sympathetic response

  Sympatholytic
• Beta blockers

  -OLOL
• Atenolol, Propanol, Metropronol, Nadolol, Medanolol

  To decrease BP thus, sympatholytic drugs
• The Px underwent vagotomy it will result to

  Tachicardia
