Sensory neurons are nerve cells within the nervous system responsible for converting external stimuli from the organism's environment into internal electrical impulses.
For example, some sensory neurons respond to tactile stimuli and can activate motor neurons in order to achieve muscle contraction.
Such connections between sensory and motor neurons underlie motor reflex loops and several forms of involuntary behavior, including pain avoidance.
In humans, such reflex circuits are commonly located in the spinal cord.
