  1. Acetylcholine plays two key roles in the body:

    1. At neuromuscular junctions, it is the primary neurotransmitter responsible for triggering muscle contractions. When released from a motor neuron, acetylcholine binds to nicotinic receptors on muscle fibers, initiating muscle contraction.
    2. In the brain, acetylcholine acts as a neurotransmitter involved in many cognitive functions, including:
    • Learning and memory formation
    • Attentional processes
    • Sensory perception
    • Motivation and arousal

    Acetylcholine is particularly important in the hippocampus and cerebral cortex regions related to learning, memory storage, and retrieval. Alzheimer’s disease is associated with a deficiency of acetylcholine.
