Question

In which type of anesthesia is a deafening agent applied to the area in question to inhibit the conduction of impulses from sensory nerves to the brain?

a) Topical anesthesia
b) Local anesthesia
c) Regional anesthesia
d) General anesthesia

Answer 1

Local anesthesia is the type of anesthesia in which a deafening agent is applied to the area in question to inhibit the conduction of impulses from sensory nerves to the brain. It works by blocking voltage-gated sodium channels to prevent the transmission of pain signals to the brain and results in numbness in the specific area.

Step-by-step explanation:

The type of anesthesia in which a deafening agent is applied to the area in question to inhibit the conduction of impulses from sensory nerves to the brain is Local anesthesia. Local anesthesia is used to numb a specific area of the body, such as when a dentist injects lidocaine to numb a tooth before a procedure. Lidocaine, a local anesthetic, works by blocking voltage-gated sodium channels, which prevents the transmission of pain signals to the brain and results in numbness in the area. Unlike other types of anesthesia, local anesthesia does not cause loss of consciousness or affect the entire body.
