Biopsychology- neurons and synaptic transmission 0.0 / 5 ? PsychologyApproachesASAQA Created by: EliseCeriCreated on: 26-04-16 11:51 What are the three types of neurons? Sensory, relay and motor 1 of 13 What is the sensory neuron? they carry messages along the pns to the cns. They have long dendrites and short axels. 2 of 13 what is the relay neuron? These connect the sensory neuron to the motor and other relay neurons. They have short dendrites and short axels. 3 of 13 What is the motor neuron? The connect the CNS to effectors such as muscles and glands. They have short dentrites and long axels 4 of 13 what is the axon covered in? myelin sheath 5 of 13 what is the myelin sheath seperated by? Nodes of ranvier 6 of 13 what is action potential? When the neuron becomes positively charged for a second, causing an elecrical impulse thqt travels towards the ennd of a neuron. 7 of 13 what are neurons separated by? Synapses 8 of 13 How are signals within neurons transmitted? Electrically 9 of 13 How are signals between neurons transmitted? Chemically 10 of 13 What is released when an electrical impulse reaches the end of the neuron? a neurotransmitter 11 of 13 where is the neurotransmitter stored? synaptic vesicles. 12 of 13 What happens onse the neurotransmitter crosses the synapse? It is picked up by the postsynaptic receptor site 13 of 13
