21. Surgical cutting or destruction of central nervous tissue is now rarely used in the treatment of pain. 22. Consequently, fluid builds inside the brain, causing pressure that dilates the ventricles and compresses the nervous tissue . 23. In bilaterally symmetrical animals, nervous tissues concentrate at the anterior region, forming structures responsible for information processing. 24. The ectoderm, on the other hand, gives rise to the epidermis, the nervous tissue , and if present, nephridia. 25. Ganglioneuromas most frequently occur in the abdomen, however these tumors can grow anywhere sympathetic nervous tissue is found. 26. The epidemic was traced to protein feed supplements infected with brain and nervous tissue extracted from sick cows. 27. Neuronal NOS ( nNOS ) produces NO in nervous tissue in both the central and peripheral nervous system. 28. This is the most common form of autowaves in biological media, such as nervous tissue , or the myocardium. 29. This influences various homeostatic processes of the nervous tissue including volume regulation and the control of blood flow. 30. Strong electric currents may cause a localized lesion in the nervous tissue , instead of a functional reversible stimulation.
