Question

To achieve spinal anesthesia,a -caine drug is injected into the
A) lateral ventricle.
B) central canal.
C) subarachnoid space.
D) dorsal root ganglia.

Accepted Answer

Spinal anesthesia is achieved by injecting a local anesthetic drug, typically a -caine drug, into the subarachnoid space, which is the space between the arachnoid mater and the pia mater membranes surrounding the spinal cord. From there, the drug can diffuse into the spinal cord and block nerve impulses, leading to anesthesia in the lower half of the body. The other options listed (lateral ventricle, central canal, and dorsal root ganglia) are not appropriate sites for spinal anesthesia.
