Youth Protection Training. Youth Protection training is designed to help you keep our youth safe from abuse. You will learn the Boy Scouts of America's Youth Protection Guidelines, signs of abuse, and how to report suspected abuse. After each section of material, you will answer questions about that section's topic.
1. How Nerve Cells Work Nerve cells process and transmit information by electrical and chemical signalling. Chemical signalling occurs via synapses, in a process known as synaptic transmission. This is a process where the axon terminal of one cell impinges upon a dendrite or soma of another [or less commonly to an axon].
Nerve cells need to be able to send messages to each other quickly and clearly. One way that nerve cells communicate with their neighbors is by sending a burst of small neurotransmitter molecules. These molecules diffuse to the neighboring cell and bind to special receptor proteins in the cell surface. These receptors then open, allowing ions to flow inside. The process is fast because the small neurotransmitters, such as acetylcholine or serotonin, diffuse rapidly across the narrow synapse between the cells.
