Document Summary

3. 2 how the nervous system works: cells and neurotransmitters. Neurons cells found in the nervous system responsible for sending and receiving information throughout the body. Responsibility is to fire receive input from one group of neurons and transmit that information to other neurons. Cell body contains the nucleus that houses the cell"s genetic material. Dendrites branches from the cell body that receives messages from other cells and transmits those messages towards the rest of the cell. Axon hillock impulses from cells travel across the neuron to the base of the body known as the axon hillock. Axon transports information in the form of electrochemical reactions from the cell body to the end of the neuron. Neurotransmitters found in vesicles that act as a messenger allowing neurons to communicate with each other. Sensory neurons receive information from the bodily senses and bring it towards the brain. Motor neurons carry messages away from the brain and spinal chord towards muscles.
