A neuron is a specialized cells that transmits nerve signals. The nervous system has two parts, the central nervous system and the peripheral nervous system. The central nervous system is what acts as the integrating signal. The peripheral nervous system then is further broken down into two parts, the sensory division which sends signals to the CNS through afferent neurons. The other part is the efferent nervous system which takes the signals from the CNS to the target cells via efferent signals. Efferent signals are what leave. Afferent is responsible for the input of signals to the CNS from somatic, special, and visceral signals. Efferent is responsable for the output from the CNS. Efferent signals then go to either somatic or autonomic controls, autonomic are the things in which you cannot control. 

The neuron itself is made up of a couple different parts. The dendrites are what recieve the signals, they either recieve nuerontransmitters or hormones. The dendrites extend from the cell body, which is where everything is made. The nucleus is found in the cell body. The signals are integrated in the axon hillock, which is near the edge of the cell body and this is where the action potential is generated. The action potentials are propagated in the axon and the neurontransmitters are released in the presynaptic terminal. This is the basic structure of a neuron.
