Dr. Stephen's Other Questions Flashcards
Name the 7 items that are within the Spinal cord.
- Dorsal Roots
- Posterior Columns - Ipsilateral Proprio and 2pt
- Lateral Spinothalamic Tract - Contralateral Pain 2 dermatomes down from the lesion
- Anterior White Commisure - Bilateral Pain
- Lateral corticospinal Tract - Ipsilateral Spastic Hemiplegia
- Anterior Horn - Ipsilateral Flaccid Paralysis
- Lateral Reticulospinal Tract - Autonomic Nervous System
List the 8 structures that are in the Brainstem
- Spinal lemnisucs - Contralateral Hemianalgesia
- Medial Lemniscus - Contralateral Proprio/2pt
- Trigeminal lemniscus
- Lateral lemniscus - Bilateral Diminished hearing with the contralateral side having more hearing loss than the other
- Descending tract of V - Hemianalgesia to the face
- Corticospinal Tract - Contralateral Spastic Hemiplesia
- Corticobulbar Tract - Supernuclear Facial Palsey (crosses over @ the Pons between CN V and VI)
