Which sensory modalities are carried in
1. the spinothalamic tract?
2. the dorsal column
spinothalamic tract: Pain, temperature, crude touch

Define the term peripheral neuropathy.
“Result of damage to your peripheral nerves

Define the term “glove and stocking” pattern.
“Symptoms of peripheral neuropathy usually start in
