synaptic transmission

Question 1

synaptic transmission

Answer 1

the process by which neighbouring neurons communicate with each other by sending chemical messages across the synaptic cleft that separates them

Question 2

chemical transmissions- synapses

Answer 2

neurons communicate with each other within groups know as neural networks

• each neuron is separated from the next by a synapse which includes the space between them (synaptic cleft) and the presynaptic terminal and postsynaptic receptor site
• signals within neurons are transmitted electrically however singulars between neurons are transmitted chemically by synaptic transmission
• when the electrical impulse reaches the end of the neuron is triggers the release of neurotransmitters from tiny sacs called synaptic vesicles

Question 3

neurotransmitter

Answer 3

chemicals that diffuse across the synapse to the next neuron
-once it crosses the gap, it is taken up by the postsynaptic receptor sites

Question 4

excitation

Answer 4

when a neurotransmitter such as adrenaline increases the positive charge of the postsynaptic neuron, increase likelihood that the neuron will fire and ass on electrical impulse

Question 5

inhibition

Answer 5

when a neurotransmitter such as serotonin makes the charge of the postsynaptic neuron more negative
-decreases the likelihood that the neuron will fire and pass on the electrical impulse
