Anesthesia Types and Their Functions

What type of anesthesia is injected into a nerve, causing loss of sensation over a particular area?

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

Final answer:


The type of anesthesia that is injected into a nerve in order to cause loss of sensation over a particular area is known as local anesthesia.

Local anesthesia is a type of anesthesia that works by blocking nerve conduction when applied in appropriate concentrations. Unlike general anesthesia, local anesthesia only targets a specific area rather than inducing total loss of sensation or consciousness.

Local anesthetics block nerve conduction when applied to nerve tissue in appropriate concentrations. This blocks the initiation and transmission of sensory impulses, effectively causing a loss of sensation in the specific area where it is administered.

Other types of anesthesia include general anesthesia, which induces a reversible loss of consciousness; epidural anesthesia, commonly used in childbirth to reduce lower body pain sensation; and regional anesthesia, which numbs a larger area of the body and is typically used for surgeries on limbs and specific regions of the body.
