Neurogenesis in the course of life by Marly De Barillas https://padlet.com/lamarly89/ij59gj2h82z8 By studying the neuron and synapses we can understand how the brain works to control all the functions of the body, thanks to the network of nerves that move as a root throughout the body. This myriad of fiber is responsible for absolutely every action that we do. en-us 2018-06-26 23:04:14 UTC 2023-05-16 16:14:11 UTC hello@padlet.com https://padlet-assets.s3.amazonaws.com/icons/Lightdecrease.png The nerves... lamarly89 https://padlet.com/lamarly89/ij59gj2h82z8/wish/268656320 Collect information and sensations from the environment and send it to the brain through the nerve cells.]]> 2018-06-26 23:14:59 UTC https://padlet.com/lamarly89/ij59gj2h82z8/wish/268656320 The human being lamarly89 https://padlet.com/lamarly89/ij59gj2h82z8/wish/268656891 Possesses  approximately 100 billion neurons in the brain.

The mental life of the human being involves the activity of the neurons system, specially the brain.

Each neuron has about 40,000 separate connections.

The body and mind work through the enormously complex interaction of signal between neurons.

  • Cell body: contains the nucleus being the genetic material.

    • Dendrites: are large numer of extesions.  Chemical messages from other neurons are received.

    • Axon: extension that is different from all the other cells. It transmits an electrochemical signal to other neurons.

    • Myelin: covers the electrical impulses.

    • Node of Ranvier: are the spaces between the myelin coating on the neuron`s axon.

    • Axon terminal: this is where the electrochemical  signal that has traveled the lenght of the axon becomes a chemical message that travels to the next neuron.

  • Multipolar: are the major neurontype found the CNS. 
  • Bipolar: are found in the retina of the eye and the olfactory system.
  • Unipolar: extends from the cell body and then branches into 2 more parts that extend in opposite directions.

    Motor Neuron relays messages from the brain or spinal cord to the muscles or organs.

    Interneurons relay messages from sensory neuron to the motor neuron.]]>     2018-06-27 00:25:57 UTC https://padlet.com/lamarly89/ij59gj2h82z8/wish/268662715     Neurons work through networks lamarly89 https://padlet.com/lamarly89/ij59gj2h82z8/wish/268663956 Synapse is the meeting point between two neurons.  It is what allows you to learn and remember.

    Some of your synapses are:
    Electrical:  inmediate group text.
    Chemical: they take more time to be received and read, but they`re used more often and are more easier to control.

    Neurotransmitters: chemical whose main function is the transfmission of information from one neuron to another through synapses. They are the most important substances in the synapses.

If you are doing exercise, sleeping, eating, learning, or even just feeling an emotion, a million of neurons are working for you. We have to thank God for our extraordinary body.]]> 2018-06-27 01:31:36 UTC https://padlet.com/lamarly89/ij59gj2h82z8/wish/268669332
