Within the brain, the autonomic nervous system is regulated by the hypothalamus. Autonomic functions include control of respiration, cardiac regulation (the cardiac control center), vasomotor activity (the vasomotor center), and certain reflex actions such as coughing, sneezing, swallowing and vomiting.he autonomic nervous system is unique in that it requires a sequential two-neuron efferent pathway; the preganglionic neuron must first synapse onto a postganglionic neuron before innervating the target organ.
Plates at our planet s surface move because of the intense heat in the Earth s core that causes molten rock in the mantle layer to move. It moves in a pattern called a convection cell that forms when warm material rises, cools, and eventually sink down.
Geologists think that movement ofconvection currents in the mantle is the major force taht causes plate motion. Suring subduction, gravity pulls one edge of a plate down into the mantle. The rest of theplate also moves This slow movement is similar to what happens in a pot of soup when gravity causes the cooler, denser soup near the surface to sink.
