Repeat to remember so...
Draw a motor neuron here. Sing the song while you're drawing.
Label the parts of the neuron. (axon, axon hillock, cell body, dendrites, myelin sheath, nodes of Ranvier, and terminal branches.)
Synaptic Communication. Label the parts as best you can. Use the following terms: presynaptic neuron, postsynaptic neuron, vesicles, neurotransmitters, ligand-gated receptor channels, reuptake ports). Then draw in the movement of Na+ ions during this process.
Starting with resting potential as the first stage of neural transmission, correctly sequence the following stages.
depolarization
reuptake
action potential
threshold
resting potential
exocytosis
The refractory period is when the neuron cannot fire. Draw a neuron, draw where the Na+ ions are during the refractory period, and write what needs to happen in order for the neuron to be repolarized.
Categorize the event of sub-structure into the correct part of the neuron.
exocytosis
threshold
reuptake
saltatory conduction
depolarization
action potential
Nodes of Ranvier
myelin sheath
voltage-gated channels
ligand-gated channels
axon
terminal branches
dendrites
axon hillock
