Study Notes
Classes of Neurotransmitters
- Five major classes include: Acetylcholine, Biogenic Amines, Amino Acids, Neuropeptides, and Miscellaneous.
Acetylcholine Receptors
- Two types of receptors are muscarine and nicotinic.
- Muscarine receptors affect smooth muscles and glands.
- Nicotinic receptors influence skeletal muscles and the central nervous system (CNS).
Nicotine's Action
- Nicotine mimics Acetylcholine by binding to nicotinic receptors, rapidly affecting the nervous system.
Biogenic Amines
- Divided into two classes: catecholamines and serotonin.
- Catecholamines consist of dopamine, norepinephrine, and epinephrine.
- Precursor for catecholamines is tyrosine; serotonin is derived from tryptophan.
Role of Enzymes
- Monoamine oxidase (MAO) is involved with biogenic amines, particularly catecholamines.
- Selective serotonin reuptake inhibitors (SSRIs) target serotonin within biogenic amines.
Drug Effects on Neurotransmitters
- MAOs prevent the breakdown of norepinephrine.
- Benzodiazepines (Benzos) act as agonists on GABA receptors.
- Examples of Benzos include Xanax, Valium, and Ambien.
- SSRIs include medications like Prozac, Paxil, and Celexa.
- Hydrazine, Nardil, and Niamid fall under MAOs.
- Nicotine acts quickly on the CNS, promoting the release of dopamine and endorphins.
Amino Acids as Neurotransmitters
- Benzos affect Amino Acids.
- Glutamate excites the CNS, while gamma-aminobutyric acid (GABA) inhibits it.
- Glycine inhibits the peripheral nervous system (PNS).
Miscellaneous Neurotransmitters
- Examples include ATP, Nitric Oxide (NO), Prostaglandins, Anandamide, and Cannabinoids.
- Neuropeptides are the most common type of neurotransmitters and include Substance P.
