Term: Acetylcholine (ACh)
Definition (Myers): A neurotransmitter that, among its functions, triggers muscle contraction.
Definition (alternative): a neurotransmitter found in both the central nervous system and the peripheral nervous system. ACh plays an important role both in learning and memory and in sending messages from motor nerves to muscles, especially in the heart, bladder and stomach. It also affects glands. *
Contextual explanation: In addition to its vital role in learning and memory, ACh is the messenger at every junction between a motor neuron and skeletal muscle. When ACh is released to our muscle cells, muscle contracts. If the transmission of ACh is blocked, our muscles cannot contract. An undersupply of these neurotransmitters marks Alzheimer's disease. In present technology, botulin is used to smooth wrinkles by paralyzing underlying facial muscles (botox).
