    en.wikipedia.org/wiki/Periférico_Norte_light...

    Periférico Norte is the second station of Line 1 of the Guadalajara light rail system from north to south, and the nineteenth in the opposite direction. This station is underground. The station is under the intersection of the Calzada Federalismo with the North Peripheral Ring (Spanish: Anillo Periférico Norte), to which its name alludes.

  3. Peripheral nervous system - Wikipedia

    en.wikipedia.org/wiki/Peripheral_nervous_system

    The peripheral nervous system is divided into the somatic nervous system, and the autonomic nervous system.The somatic nervous system is under voluntary control, and transmits signals from the brain to end organs such as muscles.

  4. Sympathetic nervous system - Wikipedia

    en.wikipedia.org/wiki/Sympathetic_nervous_system

    There are two kinds of neurons involved in the transmission of any signal through the sympathetic system: pre-ganglionic and post-ganglionic. The shorter preganglionic neurons originate in the thoracolumbar division of the spinal cord specifically at T1 to L2~L3, and travel to a ganglion, often one of the paravertebral ganglia, where they synapse with a postganglionic neuron.

  5. Neuron - Wikipedia

    en.wikipedia.org/wiki/Neuron

    A neuron, neurone, [1] or nerve cell is an excitable cell that fires electric signals called action potentials across a neural network in the nervous system.They are located in the brain and spinal cord and help to receive and conduct impulses.

    A schematic representation of long distance electric power transmission. From left to right: G=generator, U=step-up transformer, V=voltage at beginning of transmission line, Pt=power entering transmission line, I=current in wires, R=total resistance in wires, Pw=power lost in transmission line, Pe=power reaching the end of the transmission line, D=step-down transformer, C=consumers.
