[{'content': 'Saltatory conductions occurs \nSelect and explain. \nA. Conduction in presynaptic to post synaptic neuron, B. Muscles of the T-tubule system, C. In. Myelinated axons, the jumping of depolarization from node to node, D. A axon can conduct impulse in both direction', 'role': 'user'}, {'content': 'Answer: C \nExplanation: i.e. (Myelinated axon, the jumping of depolarization node to node): (87-Ganong 23rd)* In myelinated axons, depolarization jumps from one node of Ranvier to the next-Saltatory conduction.* Orthodromic conduction means conduction in one direction only one neuron called the presynaptic neuron to another neuron called the post synaptic neuron* An axon can conduct impulse in one direction only, Orthodromic and opposite direction - Antidromic conduction* Synaptic conduction is mostly orthodromic because chemical mediator is localized only in the presynaptic terminal**', 'role': 'assistant'}]
