Concept #1: Neuron Structure

Concept #2: Action Potentials

Concept #3: Neuronal Signaling Steps

Concept #4: Neurotransmitters

Practice: Match the following neuron structure with its definition 

i. Cell Body                  ____________ 

ii. Myelin Sheath         ____________ 

iii. Nerve Terminal       ____________ 

iv. Nodes of Ranvier   ____________ 

v. Synapse                   ____________ 

a. Junction through which the signal is transmitted 

b. End of the axon that branches to pass the neurons message to many cells 

c. Core of the neuron 

d. Insulates the axon so ions do not leak out of the membrane 

e. Patches of ion channels that interrupt the sheath for neuron signaling

Practice: What neuron structure is responsible for ensuring that ions do not leak out of the axon membrane?

Practice: The opening of which type of channel causes depolarization of the neuron?

Practice: An influx of calcium at the synapse causes what to happen?

Practice: Which of the following neurotransmitter types blocks Cl- channels and makes depolarization harder?

Practice: Potassium channels are mainly responsible for what?
