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.
Correct answer choice is :
2) EPOC
Explanation:
The additional oxygen one gets while still breathing hard after finishing the exercise. While exercising, lactic acid forms up after the saved glycogen in your tissues are used up. It makes up in your tissues. It is what makes your tissues burn. Its development is what makes your tissues tire and give out.
Answer:
The correct answer is - it reaches to the sensory register.
Explanation:
The Atkinson- Shiffrin model of memory is the memory model that is proposed by Richard Atkinson and Richard Shiffrin in 1968. It is also known by the names as a modal modal or a multi-store model.
It explains that hum, a memory has 3 separate components which are - 1) region where sensory information enters in the memory called sensory register, 2) the region where that holds the information input receives from long term memory and sensory register, is short term memory store. and, 3) the long term memory store is a place where explained memory lasts for the long term.
Thus, the correct answer is - it reaches the sensory register.
What are the choices? Anything positive is a healthy way.
