Synapses

Question 1

Where do synapses carry info from?

Answer 1

Axon terminals of one neuron to a postsynaptic cell

Question 2

What are examples of a post synaptic cell?

Answer 2

Neuron

Cell of organ

Gland

Blood vessels

Muscle

Question 3

What are the different types of synapses?

Answer 3

Axo-somatic (muscle)

Axo-dendritic (dendrite)

Axo-axonic (another axon)

Question 4

Where are the synaptic vesicles?

Answer 4

Inside the pre synaptic terminal

Question 5

What do neurotransmitters do?

Answer 5

Released from pre synaptic terminal

Go through synaptic cleft

Go through post synaptic terminal and open ion channels

Question 6

What are the steps of how neurons communicate?

Answer 6

Action potential reaches pre synaptic terminal

Calcium enters pre synaptic terminal

Vesicles move toward release site

Pre synaptic terminal releases neurotransmitter

Neurotransmitter binds to post synaptic membrane receptor

Membranes channel changes shape and ions enter post synaptic cell

Question 7

Neuromuscular junction steps

Question 8

How is the post synaptic potential excited?

Answer 8

By increased Na+ (depolarization)

Question 9

How is the post synaptic potential inhibited?

Answer 9

Increased chloride (hyperpolarized)

Question 10

Where does an axo-axonic synapse occur?

Answer 10

Between axon of pre synaptic and axon of post synaptic
