Study Notes
Receptors and Ion Channels
- Nicotinic receptors are directly coupled to ion channels.
Muscarinic Receptors
- Muscarine is an alkaloid that can bind to muscarinic receptors.
Electrical Excitability
- Ligand-gated receptors are responsible for the electrical excitability of nerve and muscle cells.
G-Protein Coupled Receptors
- Metabotropic receptors are coupled to G-proteins.
N1 Receptors
- N1 receptors are located in the brain, specifically in the nucleus accumbens and amygdala.
