Document Summary

Module 3. 2: how the nervous system works: cells and neurotransmitters 01/24/17. Neurons: one of the major types of cells found in the nervous system, that are responsible for sending and receiving messages throughout the body. Cell body: part of a neuron that contains the nucleus that houses the cell"s genetic material. Dendrites: branches radiating from the cell body that receive messages from other cells and transmit those messages toward the rest of the cell. Axon: transports information in the form of electrochemical reactions from the cell body to the end of the neuron. Neurotransmitters: chemicals that function as messengers 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 cord towards muscles in order to control flexion and extension.
