NEET PG DENTAL EXAM

Detailed explanation-1: -The nerve conduction in unmyelinated nerves can be theoretically described as the integration of continuous transmission of an action potential, realized by changes in ionic concentrations around NaV channels, from one NaV channel to the next.

Detailed explanation-2: -Propagation along an unmyelinated axon is referred to as continuous conduction; along the length of a myelinated axon, it is saltatory conduction. Continuous conduction is slow because there are always voltage-gated Na+ channels opening, and more and more Na+ is rushing into the cell.

Detailed explanation-3: -In nerve fibres lacking a myelin sheath, the nerve impulses move continuously and less rapidly. Unmyelinated axons include most of the postganglionic axons from autonomic ganglia.
