Intermediate filaments are grouped into six classes. To which class do neurofilaments belong?
Show answer and explanation
Correct answer: Class IV (Neurofilaments)
Neurofilaments (NF-L, NF-M, and NF-H subunits) belong to Class IV intermediate filaments. They are the most abundant structural components of the axon and their density determines axon diameter, which in turn influences the speed of nerve impulse conduction.
