If you can feel hot and cold in your hand but you cannot tell if anyone is touching your hand, there may a problem with the __ in your hand. A. proprioceptors B. chemoreceptors C. mechanoreceptors D. infrareceptors

## Step 1<br />The question is asking us to identify the type of receptors in our skin that are responsible for the sensation of touch. The options provided are proprioceptors, chemoreceptors, mechanoreceptors, and infrareceptors.<br /><br />## Step 2<br />Proprioceptors are sensory receptors located in the muscles and joints that provide information about body position and movement. They are not responsible for the sensation of touch.<br /><br />## Step 3<br />Chemoreceptors are sensory receptors that respond to chemical stimuli. They are not responsible for the sensation of touch.<br /><br />## Step 4<br />Mechanoreceptors are sensory receptors that respond to mechanical pressure or distortion. They are responsible for the sensation of touch.<br /><br />## Step 5<br />Infrareceptors are sensory receptors that respond to infrared radiation. They are not responsible for the sensation of touch.<br /><br />## Step 6<br />Based on the information provided, the correct answer is C. mechanoreceptors, as they are responsible for the sensation of touch.
