The chemical signals are neurotransmitters, which transmit the information from one neuron to the next.An action potential is a rapid, temporary change in membrane potential (electrical charge), and it is caused by sodium rushing to a neuron and potassium rushing out. The electrical signals are action potentials, which transmit the information from one of a neuron to the other.Neurons communicate via both electrical signals and chemical signals: All Khan Academy content is available for free at Neurons are specialized cells that can receive and transmit chemical or electrical signals, and they are supported by cells called glia, which provide support functions for the neurons. The information below was adapted from OpenStax Biology 35.1 and Khan Academy AP Biology The neuron and nervous system. ![]() Neurons Send and Receive both Chemical and Electrical Signals Differentiate between excitatory and inhibitory post-synaptic potentials (EPSPs and IPSPs), and predict the results of multiple co-occurring PSPs.Describe the structure and function of neuronal synapses, the process that leads to neurotransmitter release, and the role of neurotransmitters at the synapse.Interpret an action potential graph and explain the behavior of ion channels underlying each step of the action potential.Identify and differentiate between the different types of ion channels that regulate neuron function.Explain the role of membrane potential in neuron communication. ![]()
