Chapter 12 nervous system suffixes
1. 2 Suffixes with the use of the Nervous System By: Ashley Barreca
2. Taxia Taxia is the internal ordering or arrangement Taxis is movement of an organism in response to an external stimulus. Ataxia is the loss of muscular coordination as a result of damage to the central nervous system, hereditary cerebellarataxiais a nervous disorder of late childhood and early adulthood.
3. Examples Using -taxia Taxiais the suffix of many words: 1. Order; arrangement: stereotaxis. 2. Responsive movement: chemotaxis. 3. Suffix meaning a specific arrangements: is a kind of biotaxis, heterotaxis, homotaxis. 4. Suffixes meaning movement of an organism in response to a stimulus: which is a type of aerotaxis, electrotaxis, geotaxis. Other terms with this suffix are: (acrotaxia, cataxia, diataxia, heterotaxia, prostaxia).
4. -Algesia An analgesic (also known as a painkiller) is any member of the group of drugs used to relieve pain (achieve analgesia). The word analgesic derives from Greek an- ("without") and algos ("pain"). Analgesic drugs act in various ways on the peripheral and centralnervous systems. 1. algesia is a pain sense. 2. excessive sensitivity to pain, a type of hyperesthesia. 3. Hyperalgesia is the extreme sensitivity of pain.
5. Based on a Study(hyperalgesia & analgesia) Action at Central Nervous System Sites in Rat with the use of morphine: Analgesia or Hyperalgesia Depending on Site and Dose Morphine was injected in various subcortical sites in the rat brain. Ten microgramsof morphine in the posterior hypothalamus resulted in siginificantanalgesia, while the same dose injected into the medial septum,the caudate, or the periaqueductal gray matter yielded hyperalgesia. The morphine-produced hyperalgesiawas accompanied by stereotyped violent circular leaps, an effectof morphine not previously reported. Thus, intracerebral injectionsof morphine differ significantly from systemic injections andproduce either analgesia or hyperalgesia, depending on siteand dose. Analgesic drugs act in various ways on the peripheral and central nervous systems;
