Explanation

Neuromuscular blocking agents (NMBAs) come in two forms: 

• Depolarizing neuromuscular blockers: Succinylcholine is the depolarizing neuromuscular blocker

• Nondepolarizing neuromuscular blockers:  can be divided into two classes based on their chemical structure:
  

steroidal (e.g., rocuronium, vecuronium, pancuronium) 

benzylisoquinolinium (e.g., mivacurium, atracurium, cisatracurium).
