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:
1. Public health activity
2. Government administration in healthcare.
Explanation:
There are various sectors of health education based on the social way of living, two of which are:
1. Public health activity: this a sector of health education that promotes the safety and enhancement of the health of individuals, families, and communities or the entire population at large.
2. Government administration in healthcare: this also a sector of health education that promotes positive health in individuals in a state. Majorly, some of the area of importance here are: public health research, leadership, globalization, and accountability

The correct answers are, A is unhealthy, B and C are Healthy.
Explanation:
First of all, we need to realize that we have to eat everything that God has made for us. But eating it in a selected controlled portions will make us remain fit and healthy. Excess of everything is bad, even if it is healthy.
We should eat everything, whether is is carbohydrates, proteins, fruits, etc. But everything should be eaten in balanced and medium portions.
So
- Option A has a huge steak, which is a protein, which is good for the body, but eating it with a huge plate of corn is not suitable because corns contain significant amount of sugary content. So this makes this option unhealthy.
- Option B is a plate of rice and vegetables, which is a healthy option, as the plate size is medium and it has both carbs and vegetables which make it a balance healthy diet.
- Option C is a small piece of chicken, which is protein, a small plate of rice, which is carbs, and a small salad, which is vegetables. This is the most healthiest and balanced option, as it contains all nutrients in a balanced size.
