How does olfaction occur?
Within the nasal cavity, odorant molecules interact with the cilia on odorant receptor cells. The binding of odorant molecules onto receptor proteins causes a net change in the membrane permeability of the receptor cells which then causes an action potential to be generated by the receptor cell. Unlike other senses, olfaction is not redirected by the Thalmus. It instead goes directly from the afferent receptor cells to the olfactory bulb. From the olfactory bulb, the action potential is sent directly to the cerebral cortex, specifically the limbic system (this is why there is a large emotional association with smell).
Which cell must have action potentials to produce one or more action potentials in the postsynaptic cell?
A neuron (nerve cell) receives dendritic input in order to generate action potentials to transmit signals of the same. After the action potential triggers release of neurotransmitters in the axonal terminal of that neuron, those neurotransmitters propagate the signal forward to the next neuron, and so forth.
When the electrical potential in a cell is in action versus a resting state the electrical charge reversal?
Action Potential
Do axons carry action potentials away from the cell body?
The areas that have had the action potential are refractory to a new action potential.
Dendrites conduct both graded and action potential?
no, dendrites and cell bodies can only have graded potential. action potential only occurs in axons
What happens to a cell when you have just Na in a cell?
all that happen is that the cell become highly positive and become unable to generate action potential. simply it goes in a long resting condition

What part of the muscle cell membrane contain acetylcholine receptors?
When the Ach binds to receptor sites on the muscle cell membrane it causes channels to open and allows Na+ to move into the cell which then causes an action potential.

What is the Difference between a receptor and an action potential?
action potential has a threshold stimulus and depolarization is just change in membrae potential where inside becomes for positive relative to outside. The AP has the ability to actually transmit info over long distance in axons once threshhold stimulus/depolarization is reached
Dendrites conduct both graded and action potential?
no, dendrites and cell bodies can only have graded potential. action potential only occurs in axons
What is agonsit?
An agonist is a chemical that binds to a receptor of a cell and triggers a response by the cell. An agonist often mimics the action of a naturally occurring substance.
How do neurotransmitters initiate action potentials?
Neurotransmitters can help bring another neuron to the point where it initiates an action potential by binding to postsynaptic receptor sites. If the receptors are the type that allow positively charged ions to flux through the cell membrane, and if this happens on a large enough scale (i.e., multiple sites are hit at once), then the probability of an action potential occurring becomes very high.
