In solid state electronics, either pure silicon or germanium may be used as the intrinsic semiconductor which forms the starting point for fabrication. Each has four valence electrons, but germanium will at a given temperature have more free electrons and a higher conductivity.

Three-neuron reflex arc.Etymology: L, reflectere, to bend back, arcus, bow. a simple neurologic unit of a sensory neuron that carries a stimulus impulse to the spinal cord, where it connects with a motor neuron that carries the reflex impulse back to an appropriate muscle or gland. simple neurologic unit of a sensory neuron that carries a stimulus impulse to the spinal cord, where it connects with a motor neuron that carries the reflex impulse back to an appropriate muscle or gland.
