Social Science Psychology QA Library The axon of a neuron would be described as a. In size the axon may represent over 95 of the total volume of the neuron. The axon looks like a tail attached to a neuron cell and is one of the largest and most important structures of nerve cells in the body.

Nissi Bodies 5 points QUESTION 2 Which is described as the neurons Secretory region. Transport of material along the huge axon has been described as a vastly complex process. Question 28 The neuron doctrine as described by Ramon y Cajal includes all of the following EXCEPT.

What is action potential in nervous system. Terminus e Nissl Bodies QUESTION 3 5 points Sov Where. It is described in more detail below.

It joins the cell body at a specialized junction called the axon hillock. The transmitting part of the neuron. An axon divides into many little branches towards the end of the neuron into axon terminals.

Axon hillock baxon cdendrite d. Provide support for axon hillock and axon. Each neuron in your brain has one long cable that snakes away from the main part of the cell.

Memorize flashcards and build a practice test to quiz yourself before your exam. The place at which the axon of one neuron comes in close contact to the dendrite from PSYC 1000 at University of Winnipeg. Axon is the projection in the long slender form of a neuron or nerve cell that are single per cell.

Neurons can have a variety of different axon structures from just one axon tail to several that branch off to different nearby neurons and exponentially increase the complexity of the way that the nervous system and brain functions. Neuroscientists use other words such as. Positively charged sodium and potassium ions b.

Axons are the elongated portion of the neuron located in the center of the cell between the soma and axon terminals. QUESTION 1 5 points Which is described as the neurons Receptive region. Functionally it carries electrical impulses and projects to synapses with dendrites or cell bodies of other neurons or with non-neuronal targets such as muscle fibers.

Now research shows that maintaining the polarity of the neuronthe enormous difference between the various compartments of the axon and dendritesis a massive job. Iv Neurons releasing acetylcholine are described as cholinergic neurons and those releasing noradrenaline are described as adrenergic neurons.
