DO NOW WEDNESDAY Explain how you think the brain sends and receives messages to and from the body.

PLAN To describe the structure and function of a sensory/motor neuron. To gather and synthesize information that sensory neurons respond to stimuli by sending messages to the brain for an immediate response or for storage as memory. DO PowerPoint Notes over Neurons Color and complete neuron picture

Neurons (Nerve Cells) www.brainpop.com

Characteristics of Neurons Are nerve cells Are the longest cells in the body Function like the wires in electronics Carry messages from the brain to the body or the body to the brain

Structure of a Neuron

Types of Neurons There are two type of neurons: A. Sensory: allow you to sense your environment; carry messages from your body to your brain; connect your brain to your five senses (eyes, ears, skin, tongue, nose) B. Motor: allow you to respond to your environment; carry messages from your brain to your body connect your brain to your muscles to allow movement

Function of Neuron Parts Dendrites: receive the chemical signal (neurotransmitter) from the adjacent nerve cell Cell body: produces the energy and protein that builds and maintains the nerve cell Nucleus: control center of the nerve cell, direct its function Axon: the “wire” of the nerve signal; conducts the electrical impulse Myelin sheath: the fatty insulation that keeps the electrical signal on the axon Axon terminals: send the chemical signal (neurotransmitter) to the next nerve cell or another cell such as a muscle cell

How does a Neuron send a signal? Neurotransmitter chemical signal  dendrites axon  electricity Axon terminals

How does a Neuron send a signal? Dendrites receive neurotransmitter from adjacent neuron. Neurotransmitter generates electrical signal in neuron. Electrical signal travels down axon and axon terminals. Neurotransmitter is released by axon terminals. Neurotransmitter travels across synapse and is received by dendrites of next nerve cell. Steps 1-5 are repeated over and over as message is sent from brain to body (by way of motor neurons) or body to brain (by way of sensory neurons). NOTE: The receiving cell of the neurotransmitter can be a muscle cell if the sending cell is a motor neuron.

What happens then? Once the message reaches its destination, what happens depends upon the destination. If the destination was the brain, then the brain will process the information and send a response message out to a part of the body or may store the information for future use (memory and learning). If the destination was a body part, then that body part will do what was instructed by the brain.
