© 2026 Assignment
Receptor Type: Ligand-Gated ion Channel Ans: Nicotinic
Guru01 - Stuvia
Receptors
Expert
Molecular Events: Opens Na+ channels on post-synaptic
neuron; Produces EPSP; Propagates Action Potential Ans:
Nicotinic Neuronal (Nn)
Location:CNS; Autonomic NS Ganglia Ans: Nicotinic Neuronal
(Nn)
CNS Effects: Memory, Cognition, Analgesia Ans: Nicotinic
Neuronal (Nn)
Peripheral Effects: Propagates Action Potential Ans: Nicotinic
Neuronal (Nn)
Molecular Events: Opens Na+, K+ Channels at Neuromuscular
Junction; Activates Motor Endplate Potential Ans: Nicotinic -
Skeletal Muscle (Nm)
Location: Skeletal Muscle Ans: Nicotinic - Skeletal Muscle
(Nm)
, 2
CNS Effects: None Ans: Nicotinic - Skeletal Muscle (Nm)
Somatic Effects: Contraction of Skeletal Muscle Ans: Nicotinic
- Skeletal Muscle (Nm)
Molecular Events: Activates Phospholipase C to produce
second messengers IP3 and DAG; IP3 -> Ca/CalModulin Kinase;
DAG -> Protein C Kinase; Final result is Activation via
Phosphorylation Ans: Muscarinic type 1 (M1), Muscarinic type
3 (M3)

Expert
CNS Effects: Memory, Cognition, etc. Ans: Muscarinic type 1
(M1)
Autonomic Effects: Production of HCl Ans: Muscarinic type 1
(M1)
Receptor Type: G-Protein Coupled of the Gi Type Ans:
Muscarinic type 2 (M2)
MolecularEvents:(1) B-G subunit->K+Efflux-> Hyper-
polarization; (2) Alpha-Subunit->Inhibition of Adenylate
Cyclase; Final Result is inhibition of Depolarization and
Depletion of cellular CAMP Ans: Muscarinic type 2 (M2)
Location:(1)Heart: SA Node, AVNode; BundleofHis;(2)
Presynaptic membrane of Autonomic Ganglia Ans: Muscarinic
type 2 (M2)
AutonomicEffects: Reduction of heart rate (negative
chronotropy),Reduction of contractility (negative ionotrophy),
Reduction of impulse conduction in myocardium (negative
