Solutions 2024/2025
1. To be classified as a neurotransmitter, a molecule - ANS -1. must
be released by the presynaptic action potential
2. must have a postsynaptic receptor
2. Name the types of neurotransmitter - ANS -peptides, gases and
lipids, purines, amino acids biogenic amines and acetylcholine
3. What are the most common neurotransmitters in the CNS? - ANS
-1. Glutamate (excitatory)
2. GABA (inhibitory)
4. The action of a neurotransmitter depends on its? - ANS -
Receptor
5. Ionotropic - ANS -opens up a channel
, 6. Metabotropic - ANS -doesn't open a channel instead it activates a
G protein to perform a cascade
7. Is acetylcholine's effect on nicotinic receptors to depolarize
skeletal muscle cells inhibitory or excitatory? - ANS -excitatory
8. Is acetylcholine's effect on muscarinic receptors hyper polarize
cardiac muscle cells inhibitory or excitatory? - ANS -inhibitory
9. Summation - ANS -adding of all of the signal
10. Temporal summation - ANS -one neuron over a long period
of time
11. Spatial summation - ANS -all of the neurons at one
particular time
