Pressure e. Reflex center – for coughing‚ sneezing‚ swallowing‚ and vomiting Pons (bridge) is where two respiratory centers are lodge in which works with those in the medulla to regulate breathing. Midbrain runs from the pons to the hypothalamus enclosing the cerebral aqueduct which is the tunnel connecting the 3rd and 4th ventricles.

Nervous System: an extensive network of specialized cells that carries information to and from all parts of the body. Neuron: the basic cell that makes up the nervous system and that receives and sends messages within that system. Dendrites: branchlike structures that receive messages from other neurons. Soma: the cell body of the neuron responsible for maintaining the life of the cell. Axon: tubelike structure that carries the neural message. Glial cells grey fatty cells that provide support for
