Neurons Flashcards
Dendrites
Receives incoming msgs
Soma
Contains nucleus
Axon
Electrical msg travels the length
Myelin Sheath
Fatty tissue that helps transmit faster
Synapse
Transfer msg to post-synaptic neuron(?)
Terminal Branches
Branches @ end of axon w/synaptic vessels
Axon Terminal Buds
Has synaptic vessels inside that release neurotransmitters
Receptor Sites
Receives the right neurotransmitter
Neurotransmitters
Chemicals that carry msg
Synaptic Cleft
Provides space for chemical transmission of msg
Resting Potential
State where neuron is preped to be active
Stimulus Threshold
Min lvl for stimulation needed to trigger action potential
All or Nothing Principal
Neuron completely stimulated or nothing
Action Potential
Sequence of change in impulse across membrane
Deplorization
Process of changing charges from -70mv to +10 mv
