WebA-Beta transmits more impulses and at a faster rate because of more myelination and larger diameter than A-Delta and C fibers. This allows more A-beta fibers to get through and less A-Delta and C fibers causing less perception of pain to reach the brain. WebOct 20, 2024 · A-beta fibers have a large diameter and are myelinated, resulting in quick transmission of impulses. C fibers are smaller in diameter and are not myelinated, resulting in the slower transmission of impulses. A-delta fibers, another form of A fiber, are also small in diameter and have a function similar to that of C fibers.
