Study Notes
Cholinergic Receptors Subdivided
- Cholinergic receptors are divided into two types: muscarinic and nicotinic.
Muscarinic Receptors
- Respond to muscarinic substances and acetylcholine (ACh).
- Subtypes include:
- M1: nerve endings
- M2: heart and some nerve endings
- M3: smooth muscle, glands, and endothelium
Nicotinic Receptors
- Respond to nicotine and acetylcholine (ACh).
- Subtypes include:
- NN: autonomic ganglia, causing secretion of epinephrine
- NM: neuromuscular end plate, causing contraction of skeletal muscle
