Practice questions testing deep understanding of action potentials, the human eye, ear, and brain structures.
Q1. The generation of a nerve impulse (Action Potential) is an all-or-nothing electrical event. Describe the exact role of the voltage-gated Sodium (Na+) and Potassium (K+) channels in generating the depolarization and subsequent repolarization of the axon membrane.
Q2. A person steps into a completely dark room from bright sunlight. At first, they are totally blind, but after a few minutes, they begin to see the vague shapes of objects. Explain the biological changes occurring in the retina (involving rods, cones, and rhodopsin) that cause this "dark adaptation."
Q3. Assertion (A): The cochlea of the inner ear is responsible for maintaining the body's physical balance and posture. Reason (R): The cochlea contains the Organ of Corti, which has sensory hair cells that detect movement.
