Quiz 4: Parts Of Neuron Flashcards
Dendrites
Major receptor of signals for neuron
“Tree branches”
Cell body
Also: perikaryon or soma
Processes and integrates signals and emits outgoing signals from neuron
Axon
Major transmitter of signals for neuron
“Tree trunk”
Nucleolus
Centerpiece within nucleus
“Heart within heart”
Nucleus
Heart of neuron
Control center of neuron
Mitochondria
Energy source for cell
Axon hillock
Gateway to cell
Area where axon meets cell body
Nissl bodies
Protein synthesis
Not in axon hillock
Axon terminals
Root-like telodendra endings of axon
“Tree roots”
Axon boutons
Also: buttons
Knob on end of axon terminals for presynaptic function
Synaptic vesicles
Within axon boutons
Packets of neurotransmitter substances that release to other neurons or muscles
