What is the name of the mechanoreceptor in the ear that allows us to perceive sound? A. Chemoreceptors B. Photoreceptors C. Cochlea D. Hair cells

## Step 1<br />The question is asking for the name of the mechanoreceptor in the ear that allows us to perceive sound. Mechanoreceptors are sensory receptors which respond to mechanical pressure or distortion. <br /><br />## Step 2<br />In the context of the ear, these mechanoreceptors are located in the cochlea, specifically in the hair cells. These hair cells are the sensory cells that convert the mechanical energy of sound waves into electrical signals that the brain can interpret.<br /><br />## Step 3<br />The other options provided, Chemoreceptors, Photoreceptors, and Cochlea, are not the correct answer. Chemoreceptors respond to chemical stimuli, Photoreceptors respond to light, and the Cochlea is the part of the ear where the hair cells are located, not the receptor itself.
