Study Notes
Major Parts of a Neuron
-
Dendrites:
- Branched extensions that receive signals from other neurons.
- Serve as the input zones for incoming information.
-
Soma (Cell Body):
- Central part of the neuron, surrounded by dendrites.
- Contains the nucleus and organelles, acting as the control center for metabolic activity.
-
Axon:
- A long, slender projection that transmits electrical impulses away from the soma.
- Responsible for conducting signals to other neurons or target cells.
-
Terminal Buttons:
- Bulblike structures located at the end of the axon.
- Store and release neurotransmitters during synaptic transmission, facilitating communication between neurons.
-
Synapse:
- The gap between two neurons where neurotransmitter release occurs.
- Critical for chemical signaling, allowing neurons to communicate effectively.
