What speeds up the passage of electrical messages by acting as a insulator of the neuronal signal?
The Myelin Sheath that surrounds the axon insulates the axon but also increases the speed of the message traveling down it.
A wave pattern travels down the length of the axon of a cell?
Depolarized
Where does the electricity in the brain come from?
Neurons.
The speed at which a neural impulse travels is increased when the axon is encased by an?
myelin sheath
When you change the number of neurons of an atom what else changes?
Neurons are nerve cells in the body but if you meant neutrons nothing normally happens; it sometimes increases radioactivity.
What is carried out by neurons?
axon
Does a neuron have a axon?
Most neurons contain one axon. There have never been more than one found. However, some neurons contain no axon at all.
What is the function of the dentrites?
Dendrites are attaches to the axon terminals of other neurons. The nerve impulse travel from other neurons into the corresponding neuron via dendrites.
What is the function of the axon endings?
it helps to speed up the process of transmitting messages between neurons.
Where is the axon not insulated with myelin?
Brain & spinal cord neurons are not myelinated
Where are neurotransmitters released by neurons?
The axon terminal, into a synapse.
Which part of a neuron is attached to the soma and carries messages out to other cells?
Apex question is which is a part of a neuron that sends out messages answer axon
White matter of brain composed?
myelinated axon of the neurons
Do unipolar neurons have a single short process that is an axon?
True
Sensory neurons of the PNS are?
Unipolar Sensory Neurons: large myelinated neurons with the cell body off to one side of the single dendritic-axon process. Multipolar Motor Neurons: large myelinated neurons that have many dendrites off the cell body and an axon that may branch to effect many effectors.
The junction between a motor neurons axon and the muscle cell membrane is called?
neuromuscular junction or myoneural junction
The branching fibers of the axon end in axon terminals and link with parts of other neurons?
The axon terminals of one neuron links with dendrites of the neighboring neuron.
