Neuros Body Function

The purpose of synapses is to pass chemical signals to one neurons to another one. Synapse is defined as a "where a presynaptic terminal ends in close proximity to a receiving dendrite (NIDA. 1996. 43)." The brain is an organ that controls different functions of the body. Neurons controls body functions, behaviors, and emotions but exactly how do neurons do this? First, let's define neuron. "A neuron is a specialized cell that can produce different actions because of its precise connections with other neurons, sensory receptors, and muscle cells (NIDA. 1996. 42)." Neurons have different processes or fibers called dendrites. Neurons fulfill body functions, behaviors, and emotions by passing signals across the synapse from one neuron to the next one. "Neurons from new synapses or strengthen synaptic connections in response to life experiences (NIDA.1996. 43)." Basically, the author is saying that life …show more content…
The difference between excitatory and inhibitory neurotransmitters are excitatory neurotransmitters lead to changes that generate action potential in a responding neuron. Inhibitory neurotransmitters block the changes that cause action potential to be generated in the responding cell. The function of receptors are to bind a specific chemical substance. An example of this would be, "...a dopamine but does not bind other neurotransmitters such as serotonin" (NIDA. 1996. 47)." The blood brain barrier protects neurons and glial cells from substances that could harm them in the brain. The functions of the blood brain is to keep out harmful substances that include toxins. The blood brain barrier will not allow most drugs in but it will allow drugs that are fat soluble. The types do drugs that can do this is drugs that have been abused and drugs that treat mental neurological illness. "The blood brain barrier is important for maintaining the environment of neurons in the brain... (NIDA. 1996.
