Anatomy of a Neuron
... Neurons are long, threadlike cells that carry electrochemical signals. Signals from the sensory organs may be perceived by the brain as sound, sight, smell, taste, touch, or pain; signals sent by the brain to the body may cause the skeletal muscles to contract, the internal organs to operate, or the ...
