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:
By the production of white blood cells and antibodies.
Explanation:
The immune system's job is to identify foreign object and to make antibodies and white blood cells to fight said virus.
Answer:
The BPP is an ultrasound that measures breathing, body movement, tone, and amniotic fluid volume.
Explanation:
The fetal biophysical profile, or BPP, is an exam, a type of ultrasound, that assesses the well-being of the fetus from the third trimester of pregnancy, and is able to assess the parameters and activities of the baby, from body movements. , breathing movements, proper growth, amniotic fluid volume, and heartbeat. These parameters are important because they reflect the functioning of the baby's nervous system and its oxygenation state, so that if any problem is identified, treatment can be performed as soon as possible with the baby still in the womb.
It is important that the pregnant woman undergoing this test understand what the procedure means. For this reason, we can conclude that the pregnant woman understood what BPP is when she states that "BPP is an ultrasound that measures respiration, body movement, tone and amniotic fluid volume."
The answer would have to be false
Answer:
For the first one, id pick all of them
the second one is C
:) have a nice dayyyyy
