This assignment delves into the critical role of neurotransmitters in nerve transmission, explaining the process from action potential to the release of neurotransmitters from vesicles. It highlights how these chemical messengers influence signal transmission by changing cell permeability and either stimulating or inhibiting message transmission. The assignment also discusses Alzheimer's disease, detailing how it disrupts neurotransmitter function, leading to memory impairment and cellular degeneration. The breakdown of neurotransmitters and the role of enzymes like acetylcholinesterase are explained, along with the impact of protein misfolding in Alzheimer's. The conclusion emphasizes the importance of neurotransmitters in information relay and how specific neurotransmitters influence signals, with the disease affecting the nervous system and causing memory loss. The assignment provides a comprehensive overview of the topic, linking neurotransmitter function to both normal nerve transmission and the pathology of Alzheimer's disease.
