How does saltatory conduction work? - MyTutor
This ‘jumping’ mechanism is known as saltatory conduction. It minimises the length of the axon that needs to depolarise in order for an action potential to propagate. It minimises the length of the axon that needs to depolarise in order for an action potential to propagate.
Saltatory conduction _______. (a) occurs in unmyelinated nerve …
Saltatory conduction occurs because: a) myelin is a good conductor of ions. b) voltage-gated sodium channels are concentrated at the nodes of Ranvier. c) myelin has many sodium and potassium channels to facilitate action potential generation. d) voltage-g; A nerve impulse travels down a myelinated axon by a. repolarization. b. saltatory ...

2023年11月21日 · Saltatory conduction - the jumping of electrical impulses down the axon between the spread-out nodes of Ranvier . Learning Outcomes. After viewing this lesson, check to see if you can:
Saltatory conduction is made possible by: A) the myelin sheath B) …
Saltatory Conduction: Saltatory conduction is one of the methods that an action potential will travel down the axon to the synaptic end bulb of a neuron. Saltatory conduction is much more efficient than continuous conduction. Answer and Explanation: 1
What is meant by the phrase saltatory conduction? - MyTutor
Saltatory conduction refers to the passage of an action potential along a myelinated neurone. Myelin is a lipid that forms a fatty sheath around the neurone axon and it is an electrical insulator. This means that an action potential cannot pass where there is myelin.
Continuous conduction and saltatory conduction differ in the ____.
a) is called saltatory conduction b) is faster than in an unmyelinated axon c) continues without decrement d) slows and fades with distance from the ; Saltatory conduction is made possible by: A) the myelin sheath B) large nerve fibers C) diphasic impulses D) erratic transmission of …
1. Why does myelin speed up nerve transmission, i.e. saltatory ...
Myelin forms a sheath around nerve cells that insulates the nerve and speeds up the rate of conduction of nerve impulses. It is formed by oligodendrocytes in the peripheral nervous system and Schwann cells in the central nervous system and is largely composed of lipids.

Saltatory conduction _____. (a) occurs in unmyelinated nerve fiber (b) is slower than conduction by local current flow because the myelin acts as an insulator to show the impulse down (c) involves the impulse jumping from one node of Ranvier to an adjac; When a neuron is stimulated, all of the following are observed except: a.
