The following: 1. Nature of muscarinic ACh receptors and role of G-proteins in their functions. 2. Role of stimulation of these receptors in production of hyperpolarization or depolarization. Introduction: Muscarinic ACh (Acetylcholine) receptors are present in smooth muscle, cardiac muscle cells, cells of salivary glands and other endocrine and exocrine glands. They regulate the brain, the cardiaovascular and the digestive system among many other systems. They are not able to directly bind to the ligand and G-proteins (guanyl nucleotide dependent proteins) are required for the functioning of these receptors.

Question

Definition Definition Organ system that helps in the digestion of food by mechanical and biochemical processes. The digestive system breaks down food into simpler components that enable the body to then absorb or transport nutrients. The human digestive system includes the gastrointestinal tract or alimentary canal and the associate glands. The organs of the gastrointestinal tract include the mouth, pharynx, esophagus, stomach, small intestine, and large intestine. The associated glands include salivary glands, liver, gallbladder, and pancreas.
