background image 8/22 Neurons and Neurotransmitters Neurons : basic units of the nervous system Operates through electrical impulses Communicate with other neurons through chemical signals Forms neural networks Three basic phases Reception Integration Transmission Three types of neurons Sensory: touch/feel Motor: brain telling neurons to hold it/what it feels like/how much 
pressure to apply
Interneuron: sensory and motor go throughout whole body, interneuron
doesn’t 
Reception Dendrite: branchlike extensions -They get the information and pass it through       Integration Cell body (soma): where the information is collected and passed Axon: information is transmitted to other neurons [Action potential 
happens here]
Glial: non-neuronal cells that maintain homeostasis Myelin Sheath: insulates some axons for faster movement along the
axon; covers and protects axon
Node of Ranvier: small gaps of exposed axon, where action potential
takes place; charging station
      Transmission Terminal buttons: small nodules that release chemical signals from the 
neuron to synapse [located at the end of an axon]
Synapse: space between the terminal button and dendrites of the next 
neuron
Neurotransmitters: chemicals that transmits from one neuron to another
Receptor: neurotransmitters bind to these molecules after passing across the
synapse
Action Potentials
Resting membrane potential: electrical charge of a neuron when 
inactive
-Ready for action: negative of inside and positive on outside Action potential (neural firing): electrical signal that passes along the 
axon and causes release of chemicals from terminal buttons
