The synapse

Question 1

What is a synapse?

Answer 1

Information transmit between synapses.

Where the pre sends signal to the post synapse.

Question 2

Two types of synapse

Answer 2

Electrical synapse

Chemical synapse

Question 3

Electrical synapse

Answer 3

Pas electrical signals between pre- and post-synapses

The electrical current (action potential) opens Ion channels, and ionic current flows through connexon channels and sends signal over the gap junction.

Question 4

Chemical synaps

Answer 4

AP arrives at pre-synapse and depolarization opens Ca2+ channels.

Influx of Ca2+ causes vesicles to fuse and transmitter is released into synaptic cleft (via. Exocytosis)

Binds to receptors on postsynaptic membrane and open/close channels

Postsynaptic current then excitatory or inhibitory the postsynaptic potential

Question 5

Two types of synaptic vesicles

Answer 5

• Small clear with Neurotransmitters

- Larger ones with chemicals in them.

Question 6

Neurotransmitters are mainly produced within

Answer 6

Pre Synapse

Question 7

SNARE complex

Answer 7

Molecular mechanisms of exocytosis during neurotransmitter release
