NEET PG DENTAL EXAM

Detailed explanation-1: -Considering the functional distinction between projection neurons and interneurons, cortical projection neurons (CPNs), also termed as pyramidal neurons and spinal cord projection neurons (dorsal horn neurons), usually have long axons (from several mm and up to 1 m).

Detailed explanation-2: -Axon – The long, thin structure in which action potentials are generated; the transmitting part of the neuron. After initiation, action potentials travel down axons to cause release of neurotransmitter.

Detailed explanation-3: -Some axons can extend up to one meter or more while others extend as little as one millimeter. The longest axons in the human body are those of the sciatic nerve, which run from the base of the spinal cord to the big toe of each foot. The diameter of axons is also variable.
