KNOW YOUR NEUROTRANSMITTERS $100

Choose from list!

acetylcholine

This NT is found in both the CNS and the PNS. It is involved in the control of skeletal muscle contractions. It stimulates skeletal muscle contraction at the neuromuscular junction.

KNOW YOUR NEUROTRANSMITTERS $200

Choose from list!

dopamine

This NT has its greatest effect in the CNS. It creates a sense of feeling good. Many “entertainment” drugs work by increasing this NT. Lack of it causes Parkinson’s disease.

Choose from list!

Substance P

Endorphins (enkephalins)

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.

ACTION POTENTIAL $400

The sodium potassium pump moves # of these 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.

3 Na out

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 $1000Discuss the relationship between these 3 parts of an ACTION POTENTIAL.

Ligand

Acetylcholine

Sodium

Voltage gate

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.
