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.
Test your knowledge about the action of parasympathetic drugs and acetylcholine on various organs and systems in the body. Learn about the effects on the eyes, heart rate, salivary secretion, intestinal motility, bronchial secretion, and blood pressure, as well as the uses of cholinergic agonists like carbachol and bethanechol chloride.
