What is the difference between SNS and PSNS? Include physiological function and neuronal structure

What is affected by the electrical signal sent by the third structure? (This will be the fourth structure in the arc.) Where is the cell body of the fourth structure located? What is affected by the electrical signal sent by the fourth structure? (This will be the fifth structure in the arc.) What does the fifth structure do in response to that electrical signal and how does this action protect you? Describe a situation where a reflex arc would be activated that is not described in your lesson. Assume that the reflex arc has five components to it. Please choose a reflex that involves a body part below the neck. (If you have trouble with this, do an internet search for information on reflex arcs.)

What is a protein kinase, and what is its role in a signaltransduction pathway?
