Pain Is Sometimes Known As Ystem (CNS)

Case Study 1
While Amy is cooking dinner for her family, when she is removing the pot Amy accidently touched the burner. Her skin at her finger tips cause her reflexes to take charge and she immediately pulls her finger away from the stove and this is because of what we call the sensory receptors. Our sensory receptors enable us to react to things such as when we go walking sandy beach in bare feet and step on a pointed shells or rock, or some other sharp foreign object and we quickly sit on ground to check if we are bleeding or something got stuck in our feet this is because our bodies identify pain. The pain that Amy experience is because of the brain receiving a signal from the sensory receptors. These neurotransmitters are identified as
Within seconds the CNS responds to the threat, which is Amy’s finger on the hot burner, and returns a signal back to Amy’s hand telling her to pull her finger off from hot burner. The signal sent by Amy’s brain traveled to the peripheral nervous system (PNS) by way of efferent neurons. When Amy pulled her finger from the hot burner it was an automatic response from her body which most likely was involuntary. In addition, when Amy feel the burning and pain sensation, that sent electrical impulses to the brain and back though her PNS, and back to the finer that is why she quickly remove her from the hot burner. Our body takes many components to make things happens. There were two neuron involved, to make the reflex take place which are the afferent and the efferent neurons, function in the procedure are contrary to each other. The afferent neuron which also known as sensory neurons carry the sensory information from our body to CNS (brain and spinal cord), while the efferent neuron also known as motor neurons is responsible for carrying the signal away from CNS. Afferent and efferent neurons are also responsible for voluntary muscle
His family members have noticed that he also has muffled speech and tends to shuffle when he walks. He is diagnosed with Early Onset Parkinson’s disease. According to American Parkinson Disease Association, when an individual age from 21-40 receives a diagnoses of Parkinson’s disease, it is specified as an early onset Parkinson’s disease or young onset Parkinson’s disease, younger people go through different experience because of their extraordinary life conditions (n.a). “It is not fully understood how genetic changes cause Parkinson disease or influence the risk of developing the disorder. Many Parkinson disease symptoms occur when nerve cells (neurons) in the substantia nigra die or become impaired. Normally, these cells produce a chemical messenger called dopamine, which transmits signals within the brain to produce smooth physical movements. When these dopamine-producing neurons are damaged or die, communication between the brain and muscles weakens. Eventually, the brain becomes unable to control muscle movement” (U.S National Library of Medicine, 2012). The structure of a synapse can simply break down. The
