5 important questions on Leeswerk boeken - Neurosciences

What are membrane differentiations?

Something that is seen in chemical synapses. Exist of:
- active zone in the presynaptic neuron (the place where neurotransmitter is stored and released) 
- Postsynaptic density - membrane with the neurotransmitter receptors

What is the difference between axodendritic synapse, axosomatic synapse and an axoaxonic synapse?

Axodendritic = postsynaptic membrane is on another axon
Axosomatic = postsynaptic membrane is on the cell body
Axoaxonic = postsynaptic membrane is on another axon

(Axospinous = presynaptic axon contacts a postsynaptic dendritic spine)

What is the difference between Gray's type I and II synapses (or asymmetrical vs symmetrical synapses)?

Asymmetrical/Gray's type I = membrane thickness is not the same for the pre- and postsynaptic membrane
Symmetrical/type II = same thickness

What can be said about the generation of AP at neuromuscular junctions?

An AP in the motor axon always causes an AP in the muscle cell

Which neurotransmitters are mainly responsible for transmitting in the CNS? And which NT is released at the neuromuscular junction?

CNS = glutamate, GABA or glycine
Neuromuscular junction = ACh
