This neuropeptide _______ is excitatory in
the CNS leading to pain perception.
However, in the PNS this neuropeptide
______ reduces pain by inhibiting the
previously mentioned NT.
Substance P
Endorphins (enkephalins)
ACTION POTENTIAL $400

ions to the outside of the cell and moves # of
these ions to the inside of the cell.
Fill in the specific number and ion name.

2 K in
ACTION POTENTIAL $600
Name the 3 main ions involved in an
action potential.
Calcium, sodium, potassium
ACTION POTENTIAL $800
What is the SPECIFIC role of calcium in an
action potential?
It causes the neurotransmitter vesicles to move to
the cell edge and undergo exocytosis.
ACTION POTENTIAL $1000
Discuss the relationship between these 3
parts of an ACTION POTENTIAL.
Ligand
Acetylcholine
Sodium
Voltage gate
DAILY DOUBLE
Acetylcholine acts as a
ligand on the sodium
voltage gate. The ligand
causes the gate to open
and allows Na to flow into
the cell beginning the
action potential.
