This short video segment from IdahoPTV's D4K describes the role of skin in our sense of touch. There are at least 7 different sensors in the skin that detect pain, temperature, light and hard pressure, vibration, and movement. The sensors send the signals along nerves to the brain.
CHILD: Your sense of touch is really a bunch of senses that work together and you start with your skin.
JOAN CARTAN-HANSEN: Your skin is the largest organ in the body. The layers of skin have at least seven different kinds of sensors and there are as many as a million of these microscopic touch sensors in a square inch of skin. Some of these nerves respond to light pressure. Others respond to heavy pressure. Some are activated by heat, cold or even vibrations.
So, when you touch something all that information activates the nerves and that information goes to your brain.
Academic standards correlations on Teachers' Domain use the Achievement Standards Network (ASN) database of state and national standards, provided to NSDL projects courtesy of JES & Co.
We assign reference terms to each statement within a standards document and to each media resource, and correlations are based upon matches of these terms for a given grade band. If a particular standards document of interest to you is not displayed yet, it most likely has not yet been processed by ASN or by Teachers' Domain. We will be adding social studies and arts correlations over the coming year, and also will be increasing the specificity of alignment.
