Document Summary

**chapter 1 material is straight from the textbook. Two main parts of the nervous system. Central nervous system: brain and spinal cord. Peripheral nervous system: comes off the spinal cord (ex. temperature, muscle movements) Dendrite: tree like branches that receive messages from the neurons. Neurotransmitters: chemicals that transmit information to and from neurons. Axon: tube like structures that carry messages to the cell. Neuron: nerve cells found throughout the body and brain that send and receive messages. Brain stem (controls fundamental biological function breathing) Medulla, pons, and cerebellum (regulate breathing, heart beat, and motor control) Cerebellum is like a little brain itself and has a lot to do with movement (if its damaged you might have difficulty balancing) Thalamus (relay station, directing nerve signals that carry sensory information to the cortex) Thalamus, hypothalamus, reticular formation, cerebellum, bran stem, pons, medulla. Amygdala, the cingulate gyrus, and the hippocampus deals primarily with emotions and impulses.
