2.1.3 & 2.1.4 Flashcards
true or false:
Action potentials/nerve impulses are always sent away from the cell body.
true
A type of neuron attached to a muscle.
motor neuron
This neuron may transmit nerve impulses from receptors in the eye towards the CNS.
sensory neuron
This neuron integrates information in the CNS.
interneuron
This neuron transmits nerve impulses away from the CNS to respond to a stimuli.
motor neuron
Most of these neurons are unipolar
sensory neuron
what type of neuron is this?
sensory neuron

motor neuron

interneuron
step 1 of communication between two neurons at a synapse
an action potential is generated in the dendrite
step 2 of communication between two neurons at a synapse
an action potential travels along an axon
step 3 of communication between two neurons at a synapse
the action potential reaches the axon terminal
step 4 of communication between two neurons at a synapse
synaptic vesicles move to the pre-synaptic terminal
step 5 of communication between two neurons at a synapse
neurotransmitters are released and travel across the synaptic cleft
step 6 of communication between two neurons at a synapse
receptors on the post-synaptic terminal receive the neurotransmitters
