A state's primary election or caucus usually is an indirect election: instead of voters directly selecting a particular person running for President, it determines how many delegates each party's national convention will receive from their respective state.n many states, only voters registered with a party may vote in that party's primary, known as a closed primary. In some states, a semi-closed primary is practiced, in which voters unaffiliated with a party (independents) may choose a party primary in which to vote.

A neuron (/ËnjÊÉrÉn/ NYEWR-on or /ËnÊÉrÉn/ NEWR-on, also known as a neurone or nerve cell) is an electrically excitable cell that processes and transmits information through electrical and chemical signals. These signals between neurons occur via specialized connections called synapses.
Neurons & the Nervous System. The human nervous system consists of billions of nerve cells (or neurons)plus supporting (neuroglial) cells. Neurons are able to respond to stimuli (such as touch, sound, light, and so on), conduct impulses, and communicate with each other (and with other types of cells like muscle cells).The nucleus of a neuron is located in the cell body. Extending out from the cell body are processes called dendrites and axons.eurons & the Nervous System.
