Cells in the Nervous System and Nerve Impulse Flashcards
A neuron is made up of four different parts.
- Dendrites
- Cell Body
- Axon
- Axon Terminals
The nervous system has two types of cell divisions.
Neurons
Glia
What part of a neuron receives information from other neurons?
Dendrites
What is the main function of the cell body of a neuron?
Process signals from dendrites.
The transfer of a signl processed by a neurons cell body is sent through a long strand-like portion of the neuron called?
Axon
The end of an axon that contains the neurotransmitters is called?
The Axon Terminal
Nerve transmition happens in three phases. What are they?
- Resting potential
- Action potential
- Refractory potential
The phase of neurotransmission when a neruon is ready to fire or is at rest is called?
Resting Potential
The firing or transmittig phase of neurotransmittion is called?
Action potential - a rapid deploarization that causes the potential in the neuron to become temporarily more positive than the outside environment.
