Transcript of The 3 Types of Neurons

The 3 Types of Neurons Sensory Neuron Scenario Mary-Ann is at a party and there is a DJ there. The DJ puts on a song that Mary-Ann likes and when she hears it, she starts dancing along to it. The sensory neuron in Mary-Ann's ear hears the song and sends a nerve impulse through it. The nerve impulse goes through the dendrite, into the cell body. From there, the impulse travels to the myelin coated axon and jumps over it. After the axon, it reaches the axon tips, where it turns chemical (it was originally electrical). Once the impulse has become chemical, it jumps across the synapse, and once it hits the next neuron, it once again becomes chemical (this cycle continues as long as the impulse is traveling on neurons). Once the nerve impulse gets to the brain, it goes to an interneuron, where Mary-Ann decides whether or not she wants to dance to this song (here is where she also remembers that this is a song she likes). After the interneuron in the brain decides that Mary-Ann will dance to this song, it creates a new nerve impulse that it sends to motor neurons in the leg and arm muscles so she can dance to this song.

The first one is the picture of an interneuron, the second is the sensory neuron, and the last one is a picture of a motor neuron. -they give us information about the outside world through the senses
-this is the the neuron that tells us that there is a stimulus in a scenario by gathering information about your environment
-the main sensory organs that this neuron works from are your eyes, ears, skin, your taste buds, and your nose
-they make a stimulus from the outside world a nerve impulse that they can send to an interneuron in the brain -this neuron resides in the brain
-interneurons are mostly gray
-the decisions you make are made by these neurons, they make you think the way you do
- this is the receptor in a scenario by deciding how to react -this neuron helps you move by working your muscles
-it is the effector in a scenario by reacting to your outside environment
-motor neurons also control your glands, not just your muscles
-every movement you make, every action like moving your eyes, blinking, your heart beating, etc. is made possible with motor neurons (and the other two neurons) How the three work together These 3 neurons work together by gathering information with the sensroy neuron. This neuron keeps the brain and its interneurons up to date on what is going on in the outside world by sending nerve impulses to it. The interneuron receives the information and decides how to react or respond to it. When it decides, it sends another nerve impulse, but to a motor neuron in a gland or muscle so it can carry out what the brain and its internerons wanted it to accomplish.
