Local anesthetics inhibit nerve conduction in a reversible manner without altering the nerve. The inhibition appears rapidly and for a longer or shorter duration depending on the products and the concentrations used. The extent of the territory rendered insensitive to pain depends on the modes of administration of the local anesthetic, either at the level of the nerve endings, or at the level of a nervous trunk, for example.
They act at the level of the neuronal membrane by interfering with the process of excitation and conduction. The anesthetic crosses the axon membrane, rich in lipids, in the form of base before taking up a cationic form on the internal face of the neuron where the pH is more acidic.
At this level, there is a blockage of nerve conduction by decreasing the membrane permeability to sodium ions that occurs during the depolarization phase. As the progression of the anesthetic action along the nerve increases, the threshold of excitability increases and the conduction time increases. This is completely blocked from a certain concentration of local anesthetic.
The nerve fibers are unequally sensitive to the action of local anesthetics: they disappear in order: the painful, thermal, tactile sensations.
Answer:
What are eponyms and how can you use them to find codes in the Alphabetic Index of the CPT? Provide an example
They are the disease, anatomical structure, clinical signs, syndromes, surgeries or technique whose name comes from that of the person who discovered or described it for the first time.
The CPT has a section of eponimos whereby the search is limited to finding the object of interest in that section.
An example of an eponym is Addsion keloid
Which method of finding a main term in the Alphabetic Index do you find easiest to use? Explain why.
The keyword because it allows you to find all the information related to the topic of interest
Answer:
b. in descending order (from most to least )
Explanation:
The ingredients on the label descend by the weight of each ingredient.(greatest to least)
Answer:
While HIV is a virus that may cause an infection, AIDS (which is short for acquired immunodeficiency syndrome) is a condition. Contracting HIV can lead to the development of AIDS. AIDS, or stage 3 HIV, develops when HIV has caused serious damage to the immune system. So its two different diseases that can lead to each other.
