Neuron Potential

Connection between the brain and the spinal cord. Controls the most basic life activities like breathing and heart beat

• Includes all the nerves that are NOT in the CNS

• With motor and sensory neurons

• Voluntary movements: somatic nervous system

• Involuntary movements: autonomic nervous system

• Sympathetic: controls all body reactions to stress

• Parasympathetic: this body system calms you down after stress

Its the way in which a neuron sends a message from the soma to the axon terminal

​

Action Potential

• ​Neuron is charged negatively (-70mV)

• Na+ and K+ ions ath different [] - Sodium-Potassium pump

​Resting potential

• ​Neuron reveices stimuli

• Na+ channels open

• Neuron becomes positive +40mV

​​Action potential

• ​Neuron doesn't receive stimuli

• K+ channels open

• More negative than in resting potential

​​Refractory period

Communication between 2 neurons by the release of molecules called neurotransmitters

​Synapse
