Neurotransmitter Receptors Flashcards
1
Q
What are the types of Neurotransmitter Receptors?
A
- Ionotropic
- Metabotropic
2
Q
What are Ionotropic receptors?
A
Ligand-gated ion channels
3
Q
When Ionotropic receptors open they allow for
A
Ions pass
4
Q
What kind of potentials are found in Ionotropic receptors?
A
Graded potentials, which are brief and local
5
Q
With Ionotropic receptors, the target cells are usually excited if
A
Na+ or Ca2+ passes through
6
Q
Metabotropic receptors function to
A
Activate secondary messengers in the neuron
7
Q
What is the function of secondary messengers?
A
They affect behavior of ion channels and change activities of proteins in neurons
8
Q
How is the response of target cells with Metabotropic receptors?
A
Is slow but has amplified effects due to the secondary messenger systems
