Question
Chapter 37, Problem 10TYU
Summary Introduction
To hypothesize:
How various anesthetics would block pain with the help of action potential and synapses.
Concept introduction:
If there is sufficient shifting of the membrane potential, due to depolarization, then it would result in massive change in the voltage (membrane); this is known as the action potential. Synapse is referred to as a junction that is present between two nerve cells.

outline the neurochemical transmission and inhibition of pain.
Then using the gate-control theory, devise a plan to minimize pain during your next visit to the dentist.
Why is this important for you to know in public health
A pin can be pressed against the skin lightly and elicit no response from the pain receptor. However, if the pin is jabbed into the finger, the pain receptor may be stimulated and the finger would quickly be withdrawn through a reflex arc.
Use what you know about threshold potential and the all-or-none principle to explain different levels of sensation (light touch or pain)
An example of a sensory neuron is one that leads from a pain receptor in the finger to the spinal cord. A pin can be pressed against the skin without eliciting a response from the pain receptor. However, if the pin is jabbed into the finger, the pain receptor may be stimulated and the finger would quickly withdrawn through a reflex arc.
How do we sense different types of pain (very painful vs. not painful at all)? Using what you understand about threshold potentials and the all-or-none principle, explain how it is possible to sense different levels of pain.

- In complete darkness, why are there no neural signals being sent to the brain by the retinal ganglion cells?

Shielding the injury gives it time to heal. An injured insect shows no such shielding response. Some have cited lack of such a response as evidence that insects do not feel pain.
