19.The AUTONOMIC NERVOUS system division of the PNS consists of nerves which control all of the involuntarymuscles, organs, glands, and sensory 20.The part of the ANS that is responsible for reacting to stressful events andbodily arousal is called the SYMPATHETIC DIVISION of the nervous system.21.A machine designed to record the brain wave patterns produced by electrical activity of the surface of the brain is called a(n) 22. The part of the lower brain located behind the pons that controls and coordinates involuntary, rapid, fine motor movement is called the 23.The part of the limbic system located in the center of the brain, this structure relays sensory information from the lower part of the brain to the proper areas of the cortex and processes some sensory information before sending it to its proper area and is called the THALAMUS24. The larger swelling above the medulla that connects the top of the brain to the bottom and that plays a part in sleep, dreaming, left–right body coordination, and arousal is called the PONS25. RETICULAR FORMATION is an area of neurons running through the middleof the medulla and the pons, and slightly beyond, that is responsible for 26. The HIPPOCAMPUS is a curved structure located within each temporal lobe, responsible for the formation of long-term memories and the storage ofmemory for location of objects.27.The AMYGDALA is a brain structure located near the hippocampus, responsible for fear responses and memory of fear.
