Abstract:
Acetylcholine (ACh) is a leading regulatory neurotransmitter in the nervous system, which functions both directly and as modulator of other neurotransmitters. It is found in the central and peripheral nervous system, as well as in the autonomic system-both sympathetic and parasympathetic. In the central nervous system (CNS), ACh functions not only as a neurotransmitter, but also as a modulator of cognitive functions, including long-term and short-term memory, limbic activation, and alertness. No process in the mammalian body can commence without its participation.

Cholinergic Receptors: Nicotinic
There are two types of nicotinic receptors: neuromuscular (NM/NM/N1) and neuronal (NN/NN/N2). The two families differ based on their location and selectivity to...
Cholinergic Receptors: Muscarinic
The subtypes M1, M3, and M5 couple with the Gq subunit and activate the phospholipase C (PLC) activity, mobilizing intracellular Ca2+....
Chemical Synapses
Because chemical synapses depend on the release of neurotransmitter molecules from synaptic vesicles to pass on their signal, there is an approximately one millisecond delay between when the axon potential reaches the presynaptic terminal and when the neurotransmitter leads to opening of postsynaptic ion channels. Additionally, this signaling is...

At the neuromuscular junction, these agents work by inhibiting the breakdown of acetylcholine, allowing it to remain bound to the receptor and bind to nearby receptors. This process leads to repetitive firing of the endplate, causing muscle...
