Introduction: Brain Pop “Nervous System”

The Central Nervous System Notes The nervous system is the control center for the entire body. The Nervous System is made up of the: 1. Brain 2. Spinal Cord 3. Neurons

Brain The brain is an organ of soft nervous tissue contained in the skull of vertebrates, functioning as the coordinating center of sensation and intellectual and nervous activity.

Spinal Cord The spinal cord is the cylindrical bundle of nerve fibers and associated tissue that is enclosed in the spine and connects nearly all parts of the body to the brain, with which it forms the central nervous system.

Neurons Neurons or nerve cells are specialized cells that make up your nervous system.

Neurons Neurons carry electric signals called impulses from one part of the body to another. Dendrites receive impulses while axons carry impulses away from the soma or cell body.

Label the Neuron using the following terms: Soma, Axon, Dendrite, Myelin Sheath, axon terminal. AXON MYELIN SHEATH DENDRITE SOMA AXON TERMINAL

Nervous System When an impulse reaches the axon terminal chemicals called neurotransmitters, are released into the synapse to stimulate other neurons that carry the message to the rest of your body.

Sensory Neurons Sensory neurons transmit signals from sense organs like eyes, ears and skin to the spinal cord and brain.

Motor Neurons Motor neurons transmit signals from the central nervous system to your muscles telling them to move.

Interneurons Interneurons like messengers, transmit signals between your sensory and motor neurons.

Sensory Information Sensory information processing by the brain as: 1. Memories (store information) 2. Immediate Behavioral Responses (immediate use)

Short-Term Memory Short-term memory is the capacity for holding, but not manipulating, a small amount of information in mind in an active, readily available state for a short period of time.

Long-Term Memory Long-term memory refers to the storage of information over an extended period. If you can remember something that happened more than just a few moment ago whether it occurred just hours ago or decades earlier, then it is a long- term memory.

Short Term vs. Long Term Short Term Memory Stores information for a few seconds or minutes. You brain is meant to hold an average of 7 items at a time, just enough for a phone number, but not so great for a credit card. Long Term Memory Requires an effort to retain. Motivation to remember if it is meaningful to you, you need it, or it is emotional.
