Question

What is the significance of the fact that there are no ribosomes present in the axon or axon terminal?

Answer 1

Ans. Axon Hillock is a region where plasma membrane generates nerve impulses, it also separate membrane domains between the cell body and axon. They lack ribosomes and most other cell organelles, with the exception of cytoskeletal elements and organelles that are being transported down the axon. The exclusion of organelles must effect constituting the cytoplasmic boundary for the somatodendritic and axonal domains. As the significance of absence of ribosomes are to controls the firing of the neuron and they are thus called action potential.
