Nociception

1) Nociception defines as the detection mechanisms of noxious stimuli by the primary afferent nociceptors of the peripheral nervous system (National Research Council, 2009), encoding and transferring by the central nervous system (Barrot, 2012). Noxious stimuli activates nociceptors that are in the periphery and enters in the dorsal horn of the spinal cord via dorsal root ganglion, ascends to the thalamus via spinothalamic tract. Nociception can happen without pain. Pain is an unpleasant sensory

to tissue damage; and the anticipation of tissue damage (“potential”). The definition’s footnote also states, “Pain is always subjective,”. Pain is a conscious sensation, and therefore it can be said that pain cannot exist without consciousness. Nociception on the other hand is a

“That’s the thing about pain… it demands to be felt” John Green eloquently states in the tear-jerking novel The Fault in Our Stars. Ask anyone who read the book about the supporting character, charming Augustus Grey, and quickly witness an almost physical wave of acrimony and nostalgia pass over them. Green’s unique ability to demand compassion from the reader through his cleverly compiled diction forces the reader to feel the extreme pain his characters are faced against. Pain brings people together

1. The difference between acute pain and chronic pain is based on their characteristics such as causes, function, and neuron structure. Acute pain travels along the spinothalamic tract to the sensory-motor cortex, as chronic pain is less localized in the anterolateral pathway to the brainstem. The fibers that are used in acute pain are myelinated fibers that carry signals rapidly, and when there is no stimulation the signal stops. Unlike chronic pain where the fibers are unmyelinated, carry signals

Physiotherapists frequently use massage to treat pain as it can decrease the effect of nociception and also reduce emotional distress by providing relaxation. However, massage is just one of a range of treatments that physiotherapists can use to treat pain e.g. therapeutic exercise is also used to lessen pain. The four stages of the pain pathway

Introduction In the United States, pain is the most common reason for patients to seek medical attention. According to an Institute of Medicine report in 2011, at least 116 million people in the United States suffer from acute and chronic pain every year, including up to 80% of the elderly population, affecting more American adults than heart disease, diabetes, and cancer combined.1 The national annual economic cost associated with chronic pain is estimated to be $560-635 billion (or $2000 for each

To really delve into the complexity of pain, an experience which is phenomenally unique to each individual, this essay will uncover the multifaceted definition of pain, how patients typically describe their pain, differences between fast and slow pain, different types of pain stimuli, the nerve pathways which carry signals to the brain, pain perception, central sensitisation, the clinical presentation of a person with a hypersensitivity disorder such as fibromyalgia, and finally how this case would

Pain is a sensation that humans feel in a variety of different ways. Humans react to this sensation depending on the type of pain that is felt. Physical pain may result in various forms of impaired daily living, given the severity of the injury the person has suffered, or the amount of pain being experienced. Emotional pain may become just as inhibiting as physical pain and may also impact daily functioning. Since many have experienced the same type of pain, whether it is physical or emotional

Research shows that fish respond to painful stimuli in a manner that is not just a simple reflex. In the article “Hooked on a Myth” by Victoria Braithwaite, biologists say “We shouldn’t be so quick to believe that fish don’t feel pain.” The Standing Committee of the European Convention for the Protection of Animals Kept for Farming Purposes explains, "The skin of the fish is the first line of defence against disease and provides protection from the environment. It contains sensory receptors for touch
