Presentation transcript:

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

Types of Neurons Sensory neurons Interneurons Motor neurons

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)
