What’s it’s function

Last time I mentioned that I would be talking about how the brain works well to make it less broad i’ll simplify that idea into today’s topic witch is how the brain tells muscles to work. To start let’s go over few vocabulary words.

1. Neuron-
   a specialized cell transmitting nerve impulses; a nerve cell.
2. synapse-
   a junction between two nerve cells, consisting of a minute gap across which impulses pass by diffusion of a neurotransmitter.
3. neurotransmitters-
   a chemical substance that is released at the end of a nerve fiber by the arrival of a nerve impulse and, by diffusing across the synapse or junction, causes the transfer of the impulse to another nerve fiber, a muscle fiber, or some other structure.

Pay attention to these three words because they will be used throughout today’s topic.Now then with those words in mind lets start with the first point of today’s idea of how muscles communicate with the brain. The first, part of this process stars in the brain at the sensory and control cortex’s where your brain tells the body what it’s feeling and how to move. when you go to move say your arm or leg the neurons in the brain send neurotransmitters to synapses where they the are bonded to the receptors of the cell membrane of another neuron. there are different types of neurotransmitters for different functions of you’r body two common ones are serotonin and dopamine. The next step of the process takes place after the neurotransmitters have boded to another cell the receptor of the receiving cell will open up to allow ions or atoms with more or less electrons to enter the cell. Then positively charged ions will enter the cell causing electricity to be made the allowing the signal to be sent to where it needs to go. and that is how the brain communicates with muscles.

tune in next time for the next topic of discussion.
