Study Notes
Neurotransmitters and Cholinergic Functions
- Acetylcholine (ACh) is the neurotransmitter responsible for parasympathetic and cholinergic nerve actions.
- It plays a role in regulating various bodily functions, including gut motility, heart rate, and muscle contraction.
Pharmaceuticals and Therapeutic Applications
- Bethanechol is used to stimulate gut motility in cases of ileus, a condition characterized by bowel obstruction.
- Organophosphates have the capacity to bind covalently to acetylcholinesterase, causing generalized cholinergic stimulation and paralysis of motor function.
- Pilocarpine is used to treat glaucoma by increasing the secretion of exocrine glands and decreasing intraocular pressure.
