MeSH definition : A specific subtype of muscarinic receptor that has a high affinity for the drug PIRENZEPINE.
It is found in the peripheral GANGLIA where it signals a variety of physiological
functions such as GASTRIC ACID secretion and BRONCHOCONSTRICTION. This subtype of
muscarinic receptor is also found in neuronal tissues including the CEREBRAL CORTEX
and HIPPOCAMPUS where it mediates the process of MEMORY and LEARNING.;
