The Case of the Terrible Tooth!
Part 1 --The Dentist
1. List the symptoms experienced by Mr. Gower.
Mr. Grower experiences symptoms such as feeling hot, and light headedness, and unawareness. He felt hot and warm prior to the root canal removal. Therefore this symptom is most likely hinting at some problems he got before the removal. His symptoms of lightheadedness could be due to the effects of the surgery or anesthetic. Need more information to be sure.
2. Novocain blocks action potential production at the site of injection. How do you think Novocain works on the axon membrane, and how does it block the sensation of pain?
Novocain serves to block receptors on nerve cells that sense pain. …show more content…
11. Assume that the postsynaptic cell in the diagram is a motor neuron. If Mr. Gower’s problems are associated with maintained muscle contraction, what must take place in the motor neuron to produce a maintained muscle contraction? The inhibitory synaptic cell must have more action potential that can affect the postsynaptic cell to create more IPSP to lessen the muscle contraction. With a higher number of EPSP than IPSP, Mr. Grower experiences an irregular amount of contraction of the motor neurons because action potentials are frequently fire off. IPSP is needed to tone down or relax the muscle by lessening the action potentials created in postsynaptic cell. His involuntary contractions are the cause of his locked jaw, stiff lips, and rigid neck.
12. Assume that both presynaptic neurons have action potentials. What two conditions in these presynaptic cells would produce an increase in the number of action potentials in the postsynaptic (motor) neuron? A greater frequency of action potential in the excitatory presynaptic cell and a lesser frequency of action potential in the inhibitory presynaptic
