BRAIN What is the corpus callosum? The band of axons connecting the left and right hemispheres of the cerebral cortex. Why might neurosurgeons sever it in patients? Epileptic seizures. This part of the brain is responsible for arousal/wakefulness? Reticular formation. It is in which portion of the brain? Hindbrain. What does aphasia mean? Language impairment. This term describes the brain’s ability to change and adapt after damage. Plasticity. This part of the brain is most associated with memory. Hippocampus. This part of the brain is most associated with the emotion of fear/aggressiveness. Amygdala. This part of the brain is most associated with motivation like hunger, thirst and sex drive, AND controls the pituitary gland. Hypothalamus. Which portion of the brain do these three areas reside in? Limbic system. This is the part of the brain that, when damaged, would result in an inability to speak with more than a couple words. Broca’s area. This part of the brain literally translates to “little brain.” Cerebellum. What does this part of the brain control? Motor control/balance. This part of the brain is associated with reading. Angular gyrus. Which brain imaging technique requires a radioactive dye be introduced first? PET scan. Surgical destruction of the brain is called what? Lesioning. What does an EEG measure? Electric activity of brain OR brain waves. What is the “master gland” for the body? Pituitary. These glands are responsible for metabolism, among other things. Thyroids. This part of the brain is the “switchboard.” Thalamus. Which of the senses does it not control? Smell. Visual information is associated with this lobe. Occipital. Audio information is associated with this lobe. Temporal. CELLS The body of a nerve cell is also known as what? Soma. What term would be used to describe the resting state of a neuron? Polarized. This part of the axon terminal is where neurotransmitters are stored. Synaptic vesicle. What is the gap between two neurons called? Synapse OR Synaptic gap. What are the cells called that exist to support neurons and create myelin? Glial cells. Is it possible for different strengths of neural impulses? No! This term describes why axons don’t allow in any ion. They’re selectively permeable. NERVOUS SYSTEM Which division of the nervous system controls our glands? Autonomic. Which division of the nervous system controls our conscience movement? Somatic. This branch of the nervous system is responsible for fight or flight. Sympathetic. Which of the following body parts has the greatest amount of brain tissue associated with it? Arms, Legs, Wrists, Tongue The central nervous system consists of what? Brain and spinal cord. What type of neuron allows you to feel a stubbed toe? Sensory neuron. DRUGS/NEUROTRANSMITTERS This is the process where neurotransmitters go back into the releasing neuron. Reuptake. This neurotransmitter is responsible for motor control/movement. Acetylcholine (ACh). The body’s primary inhibitory neurotransmitter is called this. GABA. This term means endogenous morphine. Endorphin. Which neurotransmitter is largely responsible for alertness and arousal? Epinephrine. This is the opposite of inhibitory. Excitatory. What does an agonist do? Mimics behavior or neurotransmitter (a drug that “fits in and opens the same keyhole”). Heroin would be an agonist for this. Endorphin. GABA is an inhibitory neurotransmitter. Is it possible to have a GABA agonist? Yes!
