The need for rapid conduction of the nerve impulse serves as a driving force that can determine and increase animal size. For an axon without myelin, the speed of impulse conduction is proportional to the diameter1/2. Therefore, in order to achieve a faster rate of conduction, species that lack myelin have to enlarge substantially their axons. Higher species achieve high conduction velocities

answer choices . Synapse; hormones. Presynaptic membrane; neurotransmitters. The transition to saltatory conduction occurred at surprisingly wide gaps and the improvement in conduction speed persisted to surprisingly small gaps. The study demonstrates that the specialized paranodal seals between myelin and axon, and indeed even the clustering of sodium channels at the nodes, are not necessary for saltatory conduction.

adj. 1. Of, relating to, or adapted for leaping or dancing. 2. Proceeding by leaps rather than by smooth gradual transitions. Saltatory conduction is the process by which action potentials are rapidly and efficiently propagated along myelinated axons.

concerning the evidence in favour of saltatory conduction in isolated nerve fibres reference is made to the recent reviews byHuxley & Stiimpffi (1949), Hodgkin(1951) andFrankenhaeuser&Schneider(1951).

conduction block in nerve roots may not be apparent due to it not being possible to reliably stimulate them. Saltatory conduction means of speeding the propagation of action potentials has evolved in vertebrates.

Furthermore, conduction block in nerve roots may not be apparent due to it not being possible to reliably stimulate them. In early Guillain-Barré or multi-focal motor neuropathy with conduction block this is relevant. In these cases conduction in the distal nerve segments may be normal.

Many axons in vertebrate nervous systems are myelinated, that is, coated with insulating layers of membranes deposited by glial cells or Schwann cells.

The transition to saltatory conduction occurred at surprisingly wide gaps and the improvement in conduction speed persisted to surprisingly small gaps. The study demonstrates that the specialized paranodal seals between myelin and axon, and indeed even the clustering of sodium channels at the nodes, are not necessary for saltatory conduction. Saltatory conduction provides two advantages over conduction that occurs along an axon without myelin sheaths. First, it saves energy by decreasing the use of sodium-potassium pumps in the axonal membrane. Secondly, the increased speed afforded by this mode of conduction allows the organism to react and think faster. Myelin sheaths, nodes of Ranvier, and saltatory conduction in neurons.

Most axons in the human nervous system are myelinated, meaning they are enclosed in a myelin sheath, a fatty deposit created and maintained by Schwann cells that acts as an electrical insulator.

myelin sheath All of the following statements are true regarding action potentials except: Saltatory conduction occurs because of the presence of salt (NaCl) around the neuron. True or False True False

Saltatory Conduction . Electrical signals travel faster in axons that are insulated with myelin. Myelin, produced by glial support cells, wraps around axons and helps electrical current flow down the axon (just like wrapping tape around a leaky water hose would help water flow down the hose).

Saltatory Conduction The process by which if insulating myelin is present on an axon then the nerve impulses that is conducted will "jump" from gap to gap in the myelin layer. Salta in spanish= jump. In the faster method called saltatory conduction, only certain parts of the axonal membrane need to be depolarized, called nodes of Ranvier. 47. Saltatory conduction is made possible by: a. the myelin sheath c. diphasic impulses b.
