Expository, descriptive, narrative, and persuasive are four different types of writing that are used to convey information to the reader. Each type of writing serves a specific purpose and can be identified by the way the information is presented.
Expository writing is used to explain or inform the reader about a particular topic. It is written in a clear and concise manner and presents information objectively, without expressing the writer's personal opinions or feelings. Expository writing is often used in academic settings, such as in textbooks or research papers, and is characterized by its use of factual evidence and logical reasoning to support the ideas being presented.
Descriptive writing is used to describe a person, place, thing, or event in detail. It is characterized by the use of vivid and sensory language, which helps the reader to visualize and understand the subject being described. Descriptive writing is often used in creative writing and in literature, such as in novels or short stories, and is meant to evoke emotions and create a sense of atmosphere for the reader.
Narrative writing is used to tell a story or relate an experience. It is characterized by the use of chronological events and includes a plot, characters, and a resolution. Narrative writing often includes elements of descriptive writing, as the writer must describe the setting, characters, and events in order to tell the story effectively. Narrative writing is often used in fiction and non-fiction, such as in novels, short stories, and biographies.
Persuasive writing is used to persuade the reader to adopt a certain point of view or take a specific action. It is characterized by the use of logical arguments, evidence, and appeals to emotion in order to convince the reader. Persuasive writing is often used in advertising, political speeches, and legal briefs, and requires the writer to carefully craft their message in order to effectively persuade their audience.
In conclusion, expository, descriptive, narrative, and persuasive writing are all important tools that can be used to convey information and ideas to the reader. Each type of writing serves a specific purpose and can be identified by the way the information is presented. Understanding the differences between these types of writing and how to use them effectively is an important skill for any writer to have.
How Can Gate Control Apply to Your Labor Pain?
Pain from a broken bone, stubbing your toe, or burning your forehead with a curling iron are examples of this type of pain. Therefore, when you work with patients or clients in pain, consider the many factors that contributes to their problem. The theory is even used to explain the benefits of dance and music for relieving labor pain. Dull, achy, sharp, stabbing, shooting, burning, or a numb sensation are some of the words patients use to describe their pain. So next time you smack that funny bone, pay attention to how the sensation changes as you vigorously rub it.
Pain and the Brain: What Is the Gate Control Theory?
So going back to the knife cut example, two people with the same degree of injury might experience and respond very differently. These same signals will activate the inhibitory interneurons, keeping the gate closed to any pain. Although historically, there have been many ways of explaining the origin and maintenance of pain, modern theories follow a biopsychosocial model. Can you actually reduce the amount of pain you experience just by being calm, cool, and collected? Pain signals are carried on unmyelinated smaller nerve fibers called Type C. The inhibitory interneuron decreases the chances that the projection neuron will fire. The sensations picked up by the large type A fibers will quickly move to the spinal cord and pass by the inhibitory interneurons which will deactivate the projection neurons that would allow pain signals to move to the brain.
When it comes to nerves that pick up information from the body and send signals to the brain, there are two primary afferent axons that are known as A and C fibers. The information is produced and reviewed by over 200 medical professionals with the goal of providing trusted, uniquely informative information for people with painful health conditions. Which is the first gateway to the heart? The A type neurons are associated with signals of touch, pressure, and temperature information. The gate control theory of pain is a scientific theory about the psychological perception of pain. Without even thinking about it, you rub your elbow. A fibers come in two types: A-delta and A-beta.
In contrast, In fact, there are many different types of pain. This message allows the brain to identify the potential damage. Other factors that have been found to exacerbate pain are cognitive e. The gate control theory of pain perception is a psychological theory that started in 1960 by the studies of Wall and Melzak. Scheman points out, body parts themselves do not feel pain; only the brain can do that.
The first type of nerve fibers have nothing to do with pain at all: these are large nerve fibers large-diameter sensory fibers that send information to the brain about touch, pressure, or vibration. Instead, there is a neurological gate inside the spinal cord that the pain signals encounter. In this lesson, we will discuss the gate control theory of pain, but before we do that, you need to have an understanding of what pain is. Patients are treated with the assumption that pain is present when they say it is and on the level that they say it is. However, this explanation is incomplete because the brain also gets to decide how the transmissions from the nociceptors are interpreted, which also are processed in the spinal cord.
Small and large nerve fibers synapse on projection cells P to the brain and on inhibitory interneurons I within the dorsal horn of the spinal cord. According to the theory, pain is a function of the balance between the information traveling into the spinal cord through large and small nerve fibers. Is one person faking how much pain they actually experienced? All of the A fibers are myelinated, while the C fibers are unmyelinated. . Â Plus, not everyone is convinced that the gate control theory of pain is valid. Although the theory accounts for phenomena that are primarily mental in nature — that is, pain itself as well as some of the psychological factors influencing it — its scientific beauty is that it provides a physiological basis for the complex phenomenon of pain. Increasing activity of the transmission cells results in increased perceived pain.
Closed gates might mute or prevent pain messages entirely, resulting in the person experiencing little or no pain. When an input to the transmission cells is allowed, an open "gate" describes that enables pain sensation. Given the information about the size and myelination, the A type of nerve fibers will carry signals of touch, pressure, and temperature to the brain much more rapidly than the C type fibers carrying pain signals. When someone gets hurt, the damaged tissues in the injury containing peripheral nerves transmit pain signals through the peripheral nervous system up to the spinal cord and the brain. It starts from zero and is increased until the stimulation becomes annoying to the patient. More Chronic Pain Info The brain commonly blocks out sensations that it knows are not dangerous, such as when the feel of tight-fitting shoes that are put on in the morning has all but vanished by the second cup of coffee. These pool the results from a number of smaller papers on a given topic, aiming to discern patterns among the data.
The Gate Control Theory of Pain: How Your Nervous System Controls Your Perception of Pain
The theory combined previous notions of pain, and attempted to answer questions on why we may perceive pain to different degrees. For example, two people can experience the same level of intense heat on their hand, yet one feels more pain than the other. Feelings like fear, anxiety, depression and a tendency to catastrophize or to imagine the worst all play a role in the way you feel physical pain. With this finding, pain research began to move toward the spinal column. No one wants to sit through a tattoo twice a week.
There are subsets of each of these types, such as A-alpha, A-beta, and A-delta. Gate Control Theory of Pain Example If there are signals carried on the larger type A nerve fibers associated with touch, pressure, or temperature changes, then those signals will reach the projection neurons rapidly and allow the signals to go forward to the brain. They go block the transmission of the nerve message and you will then feel more peaceful. The gentle stimulation of the massage is an attempt to override the pain stimulation by shutting the gate. Overusing opioids can lead to an increased sensitivity to pain over time. Focus your attention on the feeling of the ground under your feet or the feeling of the clothes touching your body. You cannot walk over to a hot stove, take a few deep breaths, and place your hand on the stove expecting no pain.
