They have specialized extensions (or "processes") called dendrites and axons. The axon ends in a terminal "bouton" (button), which contains vesicles containing special chemicals called neurotransmitters. Impulse Conduction – speed of an impulse proportionate to _____of axon (greater diameter = faster impulse) Myelinated axons conduct _____than unmyelinated axons . 9.7 The Synapse.

B) It is the part of a neuron that carries information to the cell body. C) It is a cell that sends signals to the body to move. D) It is the part of the neuron that carries information away from the cell body. 2.

Similar 2. axons - carry nerve impulses away from the cell body, can be one axon e. synaptic knobs - bulbous distal ending of the The cell body, or soma, of a neuron is like that of any other cell, containing mitochondria If the dendrites receive a strong enough signal from a neighboring nerve cell, This wave of depolarization along the axon is called an ac Axon, portion of a nerve cell (neuron) that carries nerve impulses away from the cell body.

A single nerve cell has many dendrites. The main difference between axon and dendrite is that axon carries nerve impulses away from the cell body whereas dendrites carry nerve impulses from synapses to the cell body.

Key Areas Covered. 1 In recent years, mounting evidence has revealed important functions of Wnt signalling in diverse aspects of neural development, including neuronal polarization, guidance and branching of the axon and dendrites, as well as synapse formation and its structural remodelling. The process of transferring information from one nerve cell to another cell is done by using chemical signals and electric impulses, which are electrochemical signals.

It produces all the proteins for the dendrites, axons and synaptic terminals (For instance, it is within the cell body that neuronal proteins are synthesized.) A neuron may have many thousands of dendrites, but it will have only one axon.

The process of transferring information from one nerve cell to another cell is done by using chemical signals and electric impulses, which are electrochemical signals. The information which is transferred from one neuron is often received at the dendrite by the chemical signal s, it then transfers to the cell body ( soma ), and continues across the neuronal axon as an electric impulse .

Axon--Synapse--Cell body--Dendrite e. Dendrite--Cell body--Axon--Synapse The correct order of the parts of the neuron with respect to the direction of the action potential is "dendrite, cell body, axon, synapse". The dendrites receive impulses from the synapse of another neuron.
