Nervous System • Purpose: Controls thoughts and voluntary/involuntary movements • Central Nervous System: Brain and Spinal Cord • Peripheral Nervous System: Nerves that transmit messages from the CNS to other organs
Neurons • Neurons are specialized cells that store information and carry messages within the nervous system • Cell body: contains nucleus and other organelles • Dendrite: branchlike extensions that receive messages from neighboring cells • Axon: long extension that carries electrical messages away from the cell body and pass them to other cells
Neurotransmitters • Chemical signals of the nervous system

Types of neurons • Sensory neurons: detect stimuli and transfer signals to the brain and the spinal cord (CNS) • Interneurons: receive signal from sensory neurons and relay them within your brain to pass on to motor neurons • Motor neurons: pass information from the nervous system to other tissues in the body (PNS)
