Definition
| Autonomic Nervous System (ANS) |
|
|
Term
|
Definition
| Synapse between an axon terminal and a dendrite. Carry input signals to neurons. |
|
|
Term
|
Definition
| Synapse between an axon terminal and the cell body (soma) of a neuron. Carry input signals to neurons. |
|
|
Term
|
Definition
| Synapse between two axon terminals. Can regulate the amount of chemical transmitter that is released by another axon terminal, thus inhibiting or facilitating the signal from another neuron. |
|
|
Term
|
Definition
| A synapse formed by gap junctions between two neurons. Ions flow between neurons at electrical synapses. |
|
|
Term
|
Definition
A synapse formed by an axon terminal and neuronal cell membrane. A neurotransmitter conveys the signal from the axon terminal to the neuronal cell membrane.
Associated with the most complex human behaviors, including learning and memory. |
|
|
Term
| Chemical Neurons have two parts: |
