Multiple Choice

Which of the sequence of events below best describes how hair cells sterocilia) in the rabbit ear provide the brain with information about stimulus intensity?

• A) Soft wind bends the hair, Na⁺ channels open leading to depolarization, low concentration of neurotransmitter released and low frequency of action potentials in afferent neuron to the brain.
• B) Strong wind bends the hair, K⁺ channels open leading to depolarization, high concentration of neurotransmitter released and high frequency of action potentials within the afferent neuron to the brain.
• C) Strong wind bends the hair, Na⁺ channels open leading to hyperpolarization, high concentration of neurotransmitter released and high frequency of action potentials in afferent neuron to the brain.
• D) Soft wind bends the hair, K⁺ channels open leading to hyperpolarization of the membrane, low concentration of neurotransmitter released and low frequency of action potentials within the afferent neuron to the brain.
