<span>The repolarization of cardiac muscle is due to closure of calcium (Ca) channels and potassium (K) exiting the cell when additional voltage gated K channels open.
Due to these changes within the heart, repolarization has to happen. This process refers to returning the cardiac muscle to its resting state, and the opposite process is depolarization.

Answer;
-Cochlea; rods and cones; retina
Making an analogy between hearing and vision, the auditory hair cells in the cochlea are similar to the rods and cones in the retina.
Explanation;
-There are two types of photoreceptors in the human retina, rods and cones. Rods are responsible for vision at low light levels (scotopic vision). They do not mediate color vision, and have a low spatial acuity.
-Cones are active at higher light levels (photopic vision), are capable of color vision and are responsible for high spatial acuity. The central fovea is populated exclusively by cones.
The cochlea is a portion of the inner ear that looks like a snail shell. It receives sound in the form of vibrations, which cause the stereocilia to move. The stereocilia then convert these vibrations into nerve impulses which are taken up to the brain to be interpreted.
