Question
minute amounts of botulin, a chemical produced by bacteria, and works by blocking the release of a specifie neurotransmitter from motor neurons, causing muscle paralysis. This neurotransmitter is called 29. A student had injections of Botox in an attempt to eliminate facial wrinkles. Botox contains a. dopamine b, acetylcholine GABA d. 30. James Olds and Peter Milner located reward or pleasure centers in which of the following brain structures? a. hypothalamus b. cerebellum c. medulla d. amygdala 31. To demonstrate that brain stimulation can make a rat behave aggressively, a neuroscientist should electrically stimulate the rat's a reticular formation b. c. d. amygdala cerebellum medulla 32. As a result of a stroke, a patient sustained damage to the motor cortex and now has paralysis of the right hand. Was the damage to the motor context located in the left or right hemisphere of the cerebral cortex? a. left hemisphere b. right hemisphere 33. When President John F. Kennedy was hit by a sniper's bullet in the back of his head, he died almost instantly because the bullet destroyed the part of his brain called the- controls breathing, heartbeat, and other vital body functions. which a. b. pons medulla c. amygdala d. cerebral cortex 34. Which brain structure processes information from all the senses except smell? a. medulla b. amygdala c. pons d. thalamus _-35. The cerebral cortex is located in the a. hindbrain b. midbrain c. forebrain _36. The association areas of the brain are located in the a. hindbrain b. thalamus c. limbic system d. cerebral cortexExplanation / Answer
Answer-29-(c) acetylcholine
Botulin blocks the release of acetylcholine which is a neurotransmitter at the neuromuscular junction, causing muscle paralysis.
Answer- 30- (a) hypothalamus
Hypothalamus is strongly associated with the center of reward or pleasure because of its connection in the septum.
Answer- 31- (d) amygdala
A neuroscientist should electrically stimulate the rat's amygdala.
Answer-32- (a) left hemisphere
If the stroke occurs to the right side of the brain, the left side will be paralysed while if the stroke occurs to the left side of the brain, the right side will be paralysed.
Answer-33- (a)medulla
The primary function of medulla is to regulate our breathing, heart rate and other body functions. It is located at the junction of the spinal cord and brain.
Answer-34-(d)- thalamus
Thalamus receives information from all the senses except smell. Thalamus organizes all information and trasfer it to higher brain areas.
Answer-35- (c) forebrain
The forebrain is the front portion of the brain. It consists cerebrum or cerebral cortex.
Answer-36- (d) cerebral cortex
Cerebral cortex is the largest portion of the brain and is associated with higher brain functions like thought or action.
