The arrival of positive ions at this node depolarises this section of the axon as well, initiating another action potential. This process is repeated, allowing the action
2021-02-25 · Saltatory conduction is a type of nerve impulse that occurs when an electric signal jumps from one bare segment of fiber to the next. Saltatory conduction is a type of nerve impulse that helps signals get from one place to another in a fast and efficient way.
breaks in the wrapping. These breaks are called nodes of Ranvier. The distance between these nodes is between 0.2 and 2 mm. Action potentials traveling down the axon "jump" from node to node.

Expert Answer 100% (2 ratings) The saltatory nature of these waves and their speed (60 -80 m s Ϫ1 ) suggest that their initiation and propagation is different from other cytosolic Ca 2ϩ waves, which can be described by continuous reaction-diffusion equations (Murray, 1989;Jaffe, 1993;Atri et al., 1993;Jafri and Keizer, 1995).Here we use computer simulations to investigate how a regular array of release sites influences Question: Question 4 1 Pts Es In The Process Of Saltatory Action Potential Propagation, O The Action Potential Is Triggered By Graded/local Depolarization Of The Synaptic Knob Local Currents Depolarize A Sensitive Spot Distant From The Trigger Zone. O Local Currents Hyperpolarize The Region Just Adjacent To The Trigger Zone. Ck O At Threshold, Sodium Channels The propagation of electrical impulses along axons is highly accelerated by the myelin sheath and produces saltating or "jumping" action potentials across internodes, from one node of Ranvier to the next. The underlying electrical circuit, as well as the existence and role of submyelin conduction in saltatory conduction remain, however, elusive. Answer to: Describe the differences between continuous propagation and saltatory propagation. By signing up, you'll get thousands of step-by-step continuous propagation- The propagation of an action potential along an unmyelinated axon or a muscle cell membrane, wherein the action potential affects every portion of the membrane surface. saltatory propagation- in the CNS and PNS carries action potentials along an axon much more rapidly than continuous propagation Punctate releases of Ca2+, called Ca2+ sparks, originate at the regular array of t-tubules in cardiac myocytes and skeletal muscle.
The discontinuous structure of the myelin saltatory conduction: [ kon-duk´shun ] conveyance of energy, as of heat, sound, or electricity. aberrant ventricular conduction the temporary abnormal intraventricular conduction of supraventricular impulses; called also ventricular aberration .

Saltatory conduction is a type of nerve impulse that helps signals get from one place to another in a fast and efficient way. Saltatory propagation occurs in _____ axons, in which action potentials _____. Select the best answer. A. myelinated; move from one node of Ranvier to another B. myelinated; move continuously along the axon toward the axon hillock C. unmyelinated; spread by depolarizing the adjacent region of the axon membrane D. unmyelinated; move from one node of Ranvier to another 2019-11-13 · The key difference between saltatory and continuous conduction is that saltatory conduction is the propagation of action potential along myelinated axons while continuous conduction is the propagation of action potential along unmyelinated axons.
