Answer 3

-electromyography
-nerve conduction velocity
-repetitive nerve stimulation

Question 4

Answer 4

signalment
-cats: males mostly
history
-LMN dysfunction, usually in PL
-loss of pain perception
-firm n painful muscles

Answer 6

-diag: signalment, history, clinical signs
-ultrasound
-elevated CK, AST
-tx: supportive, anti-coag.

Question 7

[immune/infectious diseases of the peripheral nerve…]
acute polyradiculoneuritis
