Our sense of touch

The sense of touch, to me, is a very amazing thing. The ability to feel certain things is easily one of the most fascinating things for me. Sensory receptors are found in many parts of the body including the skin, epithelial tissues, skeletal muscles, bones and joints, internal organs, and the cardiovascular system.

It consists both of sensory receptors and sensory (afferent) neurons in the periphery, to deeper neurons within the central nervous system. In set, the nerve cells responds to changes to the surface or internal state of the body. Nerve cells called "sensory receptors" (including thermo receptors, mechanoreceptors, chemoreceptors and nociceptors) send signals along a chain of nerve cells to the spinal cord where they may be processed by other nerve cells and then relayed to the brain for further processing.

One of the most famous illnesses of the sensory system is the Disconnection syndrome. It´s a general term for a number of neurological symptoms caused by damage to the white matter axons of communication pathways (via lesions to association fibers or commissural fibers) in the cerebrum, independent of any lesions to the cortex.
