Nociception :: Biology Essays Research Papers

Nociception chafe is possibly the most repellent wizardrys our senses bed regain. Even though we typic anyy fail to remember what disorder feels like when we be not experiencing it, we sure do not heed to knowledge injure. Despite injures unpleasantness, it has to be comprehended for what it is. Namely, a mechanism that allows us to avoid touch-and-go situations, to prevent go on revile, and to promote the healing run. twinge allows us to re transmit ourselves miscellanea dangerous situations, as we attempt to move away from noxious stimuli that reach suffering. As we attempt to escape stimuli that cause imposition after an initial tease on our clay, pain commode prevent further damage form occurring. Finally, pain promotes the healing process as we take great assistance to protect an injured consistency part form further damage as to minimize the experience of more pain. How is this unpleasant, yet helpful sensation detected? Nociception is the term ordin arily used to refer to the perception of pain. The receptors pertain in pain signal detection are aptly enough referred to as nociceptors - receptors for noxious stimuli. (1) These nociceptors are expel nerve endings that terminate just under the skin as to detect cutaneous pain. Nociceptors are alike placed in tendons and joints, for detection of bodied pain and in frame organs to detect visceral pain. bruise receptors are very numerous in then skin, hence pain detection here is well delimitate and the source of pain can be easily localized. In tendons, joints, and body organs the pain receptors are fewer. The source of pain hence is not readily localized. Apparently, the number of nociceptors also influences the duration of the pain felt. Cutaneous pain typically is of short duration, plainly may be reactivated upon new impacts, small-arm somatic and visceral pain is of longer duration. (2) It is important to note that well-nigh all body meander is fit with nocicept ors. (1, 2) As explained above, this is an important fact, as pain has primary example functions. If we did not feel pain and if pain did not impinge on our well-being, we would not seek help when our body aches. Hence, it makes evolutionary sense for the body to be so well equipped with nociceptors in almost all locations. The most notable exception to this system of logic is the brain. The brain itself has no nociceptors and wherefore is pain insensitive. Why is this all-important bodily structure not equipped with and therefore indirectly protected by nociceptors?Nociception Biology Essays Research PapersNociceptionPain is possibly the most unpleasant sensations our senses can detect. Even though we typically fail to remember what pain feels like when we are not experiencing it, we certainly do not wish to experience pain. Despite pains unpleasantness, it has to be appreciated for what it is. Namely, a mechanism that allows us to avoid dangerous situations, to prevent furt her damage, and to promote the healing process. Pain allows us to remove ourselves form dangerous situations, as we attempt to move away from noxious stimuli that cause pain. As we attempt to escape stimuli that cause pain after an initial insult on our body, pain can prevent further damage form occurring. Finally, pain promotes the healing process as we take great care to protect an injured body part form further damage as to minimize the experience of more pain. How is this unpleasant, yet helpful sensation detected? Nociception is the term commonly used to refer to the perception of pain. The receptors involved in pain detection are aptly enough referred to as nociceptors - receptors for noxious stimuli. (1) These nociceptors are free nerve endings that terminate just below the skin as to detect cutaneous pain. Nociceptors are also located in tendons and joints, for detection of somatic pain and in body organs to detect visceral pain. Pain receptors are very numerous in then skin , hence pain detection here is well defined and the source of pain can be easily localized. In tendons, joints, and body organs the pain receptors are fewer. The source of pain therefore is not readily localized. Apparently, the number of nociceptors also influences the duration of the pain felt. Cutaneous pain typically is of short duration, but may be reactivated upon new impacts, while somatic and visceral pain is of longer duration. (2) It is important to note that almost all body tissue is equipped with nociceptors. (1, 2) As explained above, this is an important fact, as pain has primary warning functions. If we did not feel pain and if pain did not impinge on our well-being, we would not seek help when our body aches. Hence, it makes evolutionary sense for the body to be so well equipped with nociceptors in almost all locations. The most notable exception to this logic is the brain. The brain itself has no nociceptors and therefore is pain insensitive. Why is this all-importa nt structure not equipped with and therefore indirectly protected by nociceptors?
