<prompt> TRUE statement regarding the AV node:The path length is greater in the N regionThe path length is greater in the N-H regionImpulse velocity is slowest in the A-N regionImpulse velocity is slowest in the N region  <response>: There are 3 regions of the AV node: A-N region -the junction between atrial fibers and nodal tissue N region - the major pa of the nodal tissue N-H region - where nodal fibers merge into His bundle The path length, for impulse propagation, is longest in the A-N region. The velocity of impulse is slowest in the N region. The N region has fibers which depolarize very slowly Most of the AV blocks occur in AN and N regions.
