Nociception

Week 7 FPP Assignment Kelsy Weavil Q1. (1a) Outline the processes of nociception: Nociception is a neural process that senses and responds to harmful stimuli, for instance in this scenario Linda rolling her ankle. Nociceptive pain comes from an actual or potential mechanical or chemical stimuli that causes injury to non-neural tissue, this is due to the activation of nociceptors. (1) Nociceptive pain has 5 phases: Transduction, Conduction, Transmission, Modulation, and Perception. • Transduction

Monoamines in Nociception Serotonin (5-HT) and norepinephrine are primary neurotransmitters of the monoamine pathway and have been implicated in chronic pain (Bardin, 2011). These monoamines, particularly in areas such as the PAG, form a depression-pain interface. The PAG takes information sent from the amygdala, neocortex, and hypothalamus, processes the information, and then sends the modified signals to the brainstem, particularly the RVM (Millan, 2002). Approximately 20% of the neurons within

speaking, a complex sensory modality that is essential in the fight for survival. (Patel, N.B. 2010) It is thought to be a defence mechanism designed by the body, for triggering behavioural reflexes that defend against further noxious stimuli. Nociception is a neural mechanism brought about by the presence of tissue damaging stimulus however, it does not reach consciousness and therefore the perception of pain may range. This range extends from the inability to perceive pain regardless of stimuli

The Perception of Pain in Conjunction to the Mind and Body The Perception of Pain in Conjunction to the Mind and Body Pain is something that connects all of us. From birth to death we can identify with each other the idea and arguably the perception of it. We all know we experience it, but what is more important is how we all perceive it. It is known that there are people out there with a ‘high’ pain tolerance and there are also ones out there with a ‘low’ pain tolerance, but what is different

The reception of pain in the peripheral nervous system to the perception of the same in the brain, and the corresponding generation of response behaviours, is achieved through several pathways. These different nociceptive pathways kick-off in a similar manner in which a pain signal coming from the skin, for instance, travels up a sensory nerve fibre made up of axons located in the spinal ganglion. The axons then enter the spinal cord, upon which they immediately divide into the upward and downward

Acute pain is a sudden onset of an unpleasant sensation and is usually sharp in quality. It serves to alert the body that something is wrong. There are many factors that could cause acute pain such as surgery, broken bones, dental work, burns, cuts, labor, or childbirth to name a few (Acute, 2014). Pain is the response triggered by the nervous system in response to tissue damage or damage to the body. Microscopic pain receptors, called nociceptor, within the skin register this occurrence and become

Endodontic pain in the context of oro-facial pain. Endodontic pain is typically derived from noxious insults to the pulp and peri-radicular tissues and the inflammation which follows. Nociceptors of the pulp and peri-radicular tissues have their cell bodies located in the trigeminal ganglia. When these primary afferent nociceptors experience membrane depolarization due to a noxious stimulus, they send an action potential to the second-order neurons whose cell bodies reside in the medulla. The second-order

Related Case Mrs. Smith signs in the emergency room with chest pain. Several nurses rush to get her vitals, blood samples to send to the lab, and obtain an EKG. While performing an assessment on Mrs. Smith, the nurse inquires about the amount of time she has been feeling this way. Mrs. Smith replies " My sister passed away 2 weeks ago and I have been having this chest pain ever since". After the physician reviews over all of Mrs. Smith 's lab and radiology test results, he informs her that she

In a literal translation fibromyalgia means muscle fiber pain. It is a chronic pain disorder that causes pain and tenderness in the muscle to the touch. By affecting the way your brain processes pain signals, researchers believe that fibromyalgia amplifies those sensations. Robert Bennett MD, explains that different parts of the brain are involved in pain reactions. Pain sensation is necessary; it serves as a reflex to avoid discomfort. This unconscious reflex of avoidance causes the brain to swiftly
