Neuron

• Neurons are responsible for transmitting information throughout the body
• Neurons receive, process, and transfer info.
• There are three types of neurons: sensory (afferent), motor (efferent), and interneurons.
• The nervous system is made up of neurons that transmit electrical signals to other cells or organs.
• Sensory neurons carry sensory information from the environment and sends the signal to the brain.
• Motor neurons communicate information from the brain to tissues and organs throughout the body, allowing for movement.
• Interneurons transmits information between the sensory and motor neurons
• This is a Sensory neuron

  
• This is a Motor Neuron

  
• This is an interneuron

  
• Dendrites are small threads around the main body of the neuron. They receive information from other neurons.
• The Soma (cell body) is the largest part of a neuron. It is responsible for chemical processing.
• An Axon is a long thin thread that carries information away from the cell.
• This is a Soma

  
• This is a Dendrite

  
• This is an axon

  
• The Myelin Sheath protects and insulates the Axon. It keeps the electrical impulses inside the axon and speeds up the transmission of impulses.
• What is the purpose of the myelin sheath?

  The myelin sheath speeds up travel time of electrical impulses
• What keeps the electrical impulse inside the axon?

  Myelin Sheath
• What is the purpose of a dendrite?

  They receive information from other neurons
• This is a myelin sheath

  
• axon terminals release neurotransmitters into the synaptic gap. This information is picked up by dendrites of the next neuron.
• What is the purpose of an Axon Terminal?

  Releases neurotransmitters into synaptic gap
• Nodes of Ranvier let in positive particles to push ions in and out
• Nodes of Ranvier are gaps between myelinated axons and are filled with gap junctions.
• This is a Node of Ranvier

  
• Dendrites receive messages from other neurons and pass them on to the cell body.
• The synaptic gap (synapse) is a gap between neurons where neurotransmitters are released.
• The synaptic gap is responsible for the transmission of information from one neuron to another.
• Neurotransmitters are chemicals that transmit information from one neuron to another across the synapse.
• Neurotransmitters are chemicals that are released from the presynaptic neuron and bind to receptors on the postsynaptic neuron
• What is a neuron

  Neurons are nerve cells that transmit information throughout the body.
• What is the function of a neuron in the Nervous System

  Transmits information/electrical impulses throughout the body.
• What is a synaptic gap?

  The gap between neurons where neurotransmitters are released.
• This is a synaptic gap
