Practice examination for the second hourly in BISC/PSYC 230. The following T/F and fill-in questions have been used in the past in this course. The answers are given at the end of the exam text. Answers are provided for many but not all of the questions. Please don’t ask for the missing answers; there is a great deal of data that indicate that students learn better (actually, much better) when they find answers for themselves. 1. T     F Von Frey was wrong about free nerve endings being exclusively for pain  perception.  But it does appear that about 1/3 of these endings are for pain. 2. T     F Pain messages from the body to the brain are thought to travel through the  dorsal columns of the spinal cord. 3. T     F Individuals who have suffered amputation of limbs often suffer from a  condition called “hallucinatory pain syndrome.” 4. T     F chronic pain in amputated limbs by cutting the dorsal columns of the spinal cord. 5. T     F to suppress transmission of pain information.  They called the neural substrates for this  process a “pain gate.” 6. T     F Pain gates have been found in the brain stem and in the thalamus, and  electrical stimulation of these sites can reduce the suffering from painful stimulation in  animals and humans. 7. T     F Enkephalin is a pituitary hormone that functions as a morphine-like analgesic. 8. T     F From birth, some individuals have no sensitivity to pain stimuli.   Because they  are oblivious to injury, they most often die from engaging in dangerous activities that  result in lethal damage to their bodies or brain. 9. T     F Yogi have developed the ability to control a number of autonomic functions,  such as heart rate, skin temperature, and bleeding.    Greene speculated that their ability to  ignore pain might be related to their control over the autonomic nervous system. 10. T     F It is now known that “c” fibers pass into the sympathetic chain, which could be  a source of sensory input to the autonomic control systems of the brain. 11. T     F Low testosterone levels are the major cause of erectile dysfunction (ED).
