  • Structure of a Neuron.

  • The nervous system helps to sense things around us.

  • Neuron is also known as the nerve cell and is the basic building block of the nervous system.

  • Scanning.

  • This is to certify that Mr. Neuron is eligible to transmit messages to the brain.

  • Alert.

  • Receptor.

  • Neurons help in receiving, processing and transmitting information.

  • Thank you for the information.

  • Steam machine.

  • 3 components of neuron.

  • Cell body or soma.

  • Dendrites.

  • Axon.

  • Let us understand each component one by one.

  • Cell body consists of the cytoplasm and the nucleus.

  • Cytoplasm.

  • Nucleus.

  • Dendrites are short projections or extensions that stretch out of the cell body.

  • Dendrites.

  • Axon is a long, thread like projection of the neuron.

  • It has an insulating and protective sheath called myelin sheath.

  • Myelin sheath is made up of fats and proteins.

  • I forgot to check the receptor.

  • The neurons carry messages in the form of electrical signals called nerve impulses.

  • Receptor.

  • Dendrites pick up impulses from receptors and pass it to the cell body.

  • The impulses then travel along the axon.

  • Axon passes these impulses to another neuron through a junction called the synapse.

  • The impulses are carried from one neuron to another.

  • These impulses are finally delivered to the brain or the spinal cord.

  • This is a popcorn, not a cookie.

  • The End.
