Unit 3 (Localisation) - Neurotransmission

Question 1

Neurotransmitters

Answer 1

Chemicals that transmit information from one synapse to the next

Question 2

Presynaptic Neuron

Answer 2

A neuron that transmits information to another neuron

Question 3

Post-Synaptic Neuron

Answer 3

A neuron that receives information from another neuron

Question 4

Synaptic Transmission

Answer 4

The process of neurons sending information to each other via neurotransmitters

Question 5

Synaptic Vesicles

Answer 5

Small sacs which contains the neurotransmitters - when presynaptic neuron fires, vesicles move toward membrane and release neurotransmitters

Question 6

Synaptic Cleft

Answer 6

The space/gap between neurons in a synapse

Question 7

2 Types of Synapses

Answer 7

Excitory and Inhibitory Synapses

Question 8

Excitory Synapses

Answer 8

Release a neurotransmitter that excites the postsynaptic neuron and allows it to reach its action potential

Question 9

Inhibitory Synapse

Answer 9

Causes the target cell to become inhibited and less likely to fire and reach action potential
