Front 1

How can integration of information come into a dendrite:

Back 1

Through spatial summation (added together) or through temporal summation (2 inputs arriving together).

Front 2

Describe the charge of a neuron:

Back 2

Electrical membrane potential of about -70mv, the inside is negatively charged compared to outside.

Front 3

Where would a graded potential be likely found on a neuron and as a result of what:

Back 3

Through the dendrite and a result of the size of the stimulus.

Front 4

Where would an action potential likely be found in a neuron:

Back 4

Through the Axon as a result of the electrical potential reaching a threshold.

Front 5

Neurotransmitter:

Back 5

Chemicals released by a neuron which trigger a response in another neuron.

Front 6

Reuptake:

Back 6

Presynaptic process of reabsorbing its own neurotransmitters after signalling.

Front 7

Agonist:

Back 7

Drugs that enhance neurotransmitter activity.

Front 8

Antagonist:

Back 8

Drugs that inhibit neurotransmitter activity.

Front 9

Describe the whole synaptic communication route:

Back 9

Neural pulse triggers neurotransmitter release from vesicles

Neurotransmitter release into post synaptic cleft and bind to to post-synaptic receptors

Neurotransmitter then undergoes reuptake.

Front 10

What parts of neurotransmission can be affected by drugs:

Back 10

Synthesis, storage, release, binding, reuptake.

Front 11

Dopamine:

Back 11

NT that influences movement, motivation and emotion.

Front 12

Acetylcholine:

Back 12

NT present at neuromuscular junctions, releases and contracts muscle fibers so i guess it controls muscle movement.

Front 13

Noradrenaline:

Back 13

NT controls arousal levels, influences learning and memory.

Front 14

Glutamate:

Back 14

NT for rapid transmission of information in the brain, critical for memory and learning.

Front 15

Serotonin:

Back 15

NT that controls mood and many mechanisms of sleep.

Front 16

What is a neuron made up of:

Back 16

sodium, potassium, chloride and anions.
