Local anesthetics block voltage-gated Na+ channels. General anesthetics are thought to activate chemically gated Cl- channels, t
hereby rendering the nervous system quiescent while surgery is performed. What specific process do anesthetics impair, and how does this interfere with nerve impulse transmission?
Answer: Anaesthesia blocks or impairs impulse transmission which helps patients not to feel pain during surgery
Explanation: . Local anesthesia affects the neural processes usually at the nodes of Ranvier by reducing the rate at which sodium ions(which are positive) flow through the membranes. Local anesthetics blocks sodium influx into the cell membranes ensuring that the minimum threshold for transmission is not reached thereby causing no pain.
General anesthesia on the other hand opens Chloride ions(which are negative ions) channel thereby allowing chloride to flow into the cell membranes causing hyperpolarization. As the negative ions increase, this shifts the membrane potential away from the minimum threshold thereby blocking the pain during surgery.
It was a slap in the face for Jewish tradition, but it was also the central reason for the rapid spread of Christianity. As the Christian movement began to accept non-Jewish members, it moved further away from the strict rules imposed on Jews.
On the other hand civic responsibilities are fulfilled by choice. They are voluntary. Civic duties include, for example, obeying the laws of the country, paying the taxes levied by the government, or serving on a jury or as a witness in court.
It is the occipital lobe that is damaged by the injury that James got. This part of the cerebral cortex is responsible for processing information for visual purposes. It is the critical part for what we see with our eyes. It is located at back portion of the brain and is behind the temporal lobes.
