Anatomy And Lesions Flashcards
Patient presents with:
- bilateral loss of pain and temp sensations in upper extremities
- spastic paralysis, hyperreflexia,hypertonic of lower extremities
- loss of proprioceptive and 2 point discrimination
Syringomyelia
Patient presents with:
- Paresis and atrophy of intrinsic muscles of hand, followed by arm and shoulders
