|Label the Brain Anatomy Diagram | |

|Instructions: Read the definitions below, then color and label the brain anatomy diagram. | |

|Try to do it from the description—without a book, use it only if you need to. | |

| | |

|Cerebellum - the part of the brain below the back of the cerebrum. It regulates balance, posture, movement, and muscle | |

|coordination. | |

|Corpus Callosum - a large bundle of nerve fibers that connect the left and right cerebral hemispheres. | |

|In the lateral section, it looks a bit like a "C" on its side. | |

|Frontal Lobe of the Cerebrum - the top, front regions of each of the cerebral hemispheres. | |

|They are used for reasoning, emotions, judgment, and voluntary movement. | |

|Medulla Oblongata - the lowest section of the brainstem (at the top end of the spinal cord); | |

|it controls automatic functions including heartbeat, breathing, etc. | |

|Occipital Lobe of the Cerebrum - the region at the back of each cerebral hemisphere that contains the centers | |

|of vision and reading ability (located at the back of the head). | |

|Parietal Lobe of the Cerebrum - the middle lobe of each cerebral hemisphere between the frontal and occipital lobes; | |

|it contains important sensory centers (located at the upper rear of the head). | |

|Pituitary Gland - a gland attached to the base of the brain (located between the Pons and the Corpus Callosum) | |

|that secretes hormones. | |

|Pons - the part of the brainstem that joins the hemispheres of the cerebellum and connects the cerebrum with the cerebellum. | |

|It is located just above the Medulla Oblongata. | |

|Spinal Cord - a thick bundle of nerve fibers that runs from the base of the brain to the hip area, | |

|running through the spine (vertebrae). | |

|Temporal Lobe of the Cerebrum - the region at the lower side of each cerebral hemisphere; | |

|contains centers of hearing and memory (located at the sides of the head). | |

The Brain Game

(Adopted from Rod Plotnik)

Directions: Read the following scenarios and explain the area of the brain that is affected.

|Scenario |What area? |

|Walking down a dark New York street late at night you suddenly feel the metal barrel of a pistol press against your head behind | |

|your ear and hear the instructions “Don’t move a muscle while I slip your wallet out of your pocket”. Unfortunately you do | |

|move, the gun is fired and the bullet enters the brain. Breathing and heart beat stop almost immediately. Where is the bullet?| |

|“Little Mo” was extremely short for his age. His doctors concluded the brain was not stimulating the proper release of hormones| |

|necessary for growth. What area of the brain are they probably focusing on? | |

|You’re in the Dome parking lot at 2 AM when a guy in a hockey mask holding a long-bladed knife jumps out at you. What system of| |

|nerves would arouse your body to action? (be specific) | |

|On Justin’s 21st birthday he & his buddies celebrated a bit too much. When the police stopped his car Justin’s speech was | |

|slurred, he couldn’t walk a straight line or balance on one foot. He nearly missed his face altogether when asked to touch his | |

|nose while his eyes were closed. The impaired functioning of what part of Justin’s brain is responsible for these difficulties | |

|with motor coordination and balance? | |

|Uncle Ed suffered a stroke which damaged a portion of his cortex. He shows some weakness and partial paralysis of his right | |

|leg. What area of his cortex was affected by the stroke? (be specific) | |

|Paul suffered from encephalitis (a brain infection) while in college. He received good medical attention but still the | |

|infection took its toll on certain parts of his brain, so that now Paul cannot store new long-term memories. What part of the | |

|brain did the encephalitis damage? | |

|Leon’s car was broadsided by a semi causing Leon’s head to smash against the driver’s side window damaging his temporal lobe | |

|cortex. What ability may be affected? | |

|Jeff suffered serious injuries when his car crashed but he was still able to crawl out of the car and pull his sister out as | |

|well. Name ONE of the transmitters that helped him function in this situation and tell how. | |

|Wayne has been diagnosed as a paranoid schizophrenic. What neurotransmitter change seems to underlie schizophrenia? | |

|Siggy the Rat had a stimulating electrode implanted in his brain. Siggy presses a bar to activate that electrode-something he | |

|would rather do than eat, sleep or have sex. Sometimes he presses 7000 times/hr. What is Siggy’s electrode stimulating? | |

|Brett was a superior student and had a full scholarship, but following a head injury he can no longer plan, organize or follow | |

|through with tasks necessary for school. (In addition he no longer shows concern for others or for common social courtesies. | |

|He’s rude and disinhibited.) Where was his injury? | |

|Jan suffered a concussion in a car accident. Since that day she has notice a dramatic decrease in her sexual libido, a lack of | |

|appetite and an absence of thirst. She never thinks of having a drink until her lips actually dry and crack. What part of her | |

|brain might have been affected by the car accident? | |

|Philip is hooked on cocaine. What neurotransmitter seems most closely related to the pleasure such drugs produce and their | |

|addictive qualities? | |

|Grandma Mary had a stroke, which impaired her ability to speak fluently although she can move all the necessary muscles. What is| |

|the most likely location of her brain damage (be specific)? | |

|Some individuals who are blind have biorhythms and sleep/waking cycles that are very different than normal. The area of the | |

|brain responsible for these cycles malfunctions without normal visual input. What region is this? | |

|Michael J. Fox has Parkinson’s disease, a motor disorder related to the death of cells in a part of the brain called the | |

|_______. | |

|Gwen’s brain has a congenital anomaly (a difference in brain anatomy that she was born with) - it lacks the main connection | |

|between the right and left hemispheres. What was Gwen born without? | |

|Sara’s grandfather has developed Alzheimer’s disease. What can you tell her about probable changes in his brain chemistry? | |

|You’re taking a short cut thru a back yard to get to your car and encounter two unrestrained Dobermans who begin pursuit. You | |

|run faster than you have ever run before, and dive into your car just in the nick of time. It takes 10 minutes for your pulse | |

|and breathing to slow down to normal. What part of the nervous system slows heart rate and breathing down to normal afterwards?| |

|Amy was having a really bad week. On Monday her vision got blurrier and blurrier until she could no longer see at all. On | |

|Tuesday she found she couldn’t hear. On Wednesday her sense of taste went. On Thursday she lost her sense of touch. Her CAT | |

|scan revealed a single brain tumor was probably producing all of these deficits. What single part of the brain in involved in | |

|all of these sensory processes? | |

|Pete was struck by lightening when he insisted on finishing his 18 holes of golf despite the lightening packed thunderstorm. He| |

|was looking down; lining up a long putt shot and the bolt of lightening struck the rear of his head, frying his occipital lobes.| |

|What aspect of behavior is likely to be impaired if Pete survives? | |

|Dana is taking Prozac to help control her depression. Prozac works by increasing the availability of what neurotransmitter? | |

|disorder that is caused by the degeneration of neuron’s that would normally produce _____________. | |

|Margie suffered damage to part of the surface of her brain after being struck by a golf club let loose by an irate golfer that | |

|had just sliced a key drive. As a result Margie has loss some sensory awareness of her left leg. Where is Margie’s brain | |

|damage (be specific). | |

|Your grandmother has begun to lose her spatial abilities—she gets lost in the neighborhood where she has spent her whole life, | |

|she can no longer read a map, she can’t put dishes or clean laundry away because she no longer knows where things go in her home| |

|of 40 years. What part of the brain mediates these perceptual/spatial abilities? | |

|After falling through the ice on a local pond little Johnny was trapped under the icy water for 10 minutes before the rescuers | |

|got him out. They were able to resuscitate his pulse and breathing but he did not regain consciousness for days. Disturbance | |

|of what specific part of Johnny’s brain might have resulted in an inability of the brain to regulate normal alertness? | |

|Jeanette suffers from focal epilepsy (seizures localized in just one part of the brain). Her seizures are triggering extreme | |

|emotions- most often extreme fear followed by a rage response. What part of the brain is being affected? | |

| | |
