Question

A long myelinated axon lacking nodes of Ranvier would: A) propagate nerve impulses faster than one with nodes of Ranvier B) propagate impulses at the same rate as one with nodes of Ranvier C) propagate nerve impulses more slowly than one with nodes of Ranvier D) propagate nerve impulses backward A long myelinated axon lacking nodes of Ranvier would: A) propagate nerve impulses faster than one with nodes of Ranvier B) propagate impulses at the same rate as one with nodes of Ranvier C) propagate nerve impulses more slowly than one with nodes of Ranvier D) propagate nerve impulses backward A) propagate nerve impulses faster than one with nodes of Ranvier B) propagate impulses at the same rate as one with nodes of Ranvier C) propagate nerve impulses more slowly than one with nodes of Ranvier D) propagate nerve impulses backward

Explanation / Answer

Answer: C) propagate nerve impulses more slowly than one with nodes of Ranvier

Explanation: Myelination of a nerve cell increases the conduction velocity of action velocity that is dependent upon nodes of Ranvier. Without nodes of Ranvier, the conduction velocity of nerve impulses gets slower.
