Synapses

Question 1

What is the synaptic cleft

Answer 1

The gap at the synapse between 2 neurones

When an action potential reaches the synapse itbis transmitted across the synaptic cleft

Question 2

What is the pre synaptic neurone

Answer 2

The neurone before a synapse
Once the action potential reaches the end of the neurone it is transmitted to the post synaptic neurone or to an effector cell

Question 3

What is the synaptic knob

Answer 3

The end of the axon in a pre synaptic neurone
This is where nerve impulses transmit a cross the synaptic cleft
It has many mitochondria for the synthesis of neurotransmitters

Question 4

Synaptic vesicles

Answer 4

In the synaptic knob abs they release neurotransmitters into the synaptic cleft

Question 5

What is the post synaptic membrane

Answer 5

Me take if the post synaptic neurone
It has receptors that have a complementary shape to the neurotransmitters releases by the synaptic vesicles
When the neurotransmitters binds to the postsynaptic membrane the action potential continues
