Mastering Cranial Nerves Through Memorable Mnemonics

Dr. Mike introduces a mnemonic to remember the 12 pairs of cranial nerves and their sensory or motor functions. The mnemonic 'O-O-O to touch and feel very good velvet are heaven' helps recall the names of the nerves. Another mnemonic, 'Some say marry money, but my brother says big brains matter most,' aids in identifying whether each nerve is sensory, motor, or both. The video explains the roles of sensory and motor nerves, providing a quick and easy method to memorize these details.
