Cards Term Somatic Nervous System Definition controls the voluntary movement of skeletal muscles Term Autonomic Nervous System Definition Control "smooth muscle" systems, such as digesting, arousal, and heart beat Term Peripheral Nervous System Definition The network of Sensory and motor neurons that connect the Central Nervous System to the body. Includes ANS, and SNS Term Central Nervous System Definition Brain and Spinal cord Term Sympathetic Division----Autonamic System Definition Governs responses to stress under contitions of threat or emergency, when action must be quick and powerfully energized---arousing Term Parasympathetic Definition Monitors the routine operation of the body's internal functions---calming Term Frontal Lobe Definition Reasoning, planning, parts of speech, and problem solving (movement, exectutive controls) Term Parietal Lobe Definition Perception of stimuli related to touch, pressure, temperature and pain (somatosensory) Term Temporal Lobe Definition Perception and recognition of auditory stimuli(hearing and memory) Term Occipital Lobe Definition visual information, color, movement, shape, shading, recognition of human faces, (vision) Term When the brain is damaged, oh goodness!, what will you do??? Definition The brain can change it's functions and shape Term psychosocialdwarfism Definition condition when children don't grow from not feeling other's human touch. Term Cerebrum Definition Largest part of brain responsible for sensing, thinking, learning, emotion, consciousness, and voluntary movement Term Corpus callosum Definition The bridge of fibers in the middle of the brain that passes information between the two cerebral hemispheres Term Thalamus Definition Part of brain that serves as the relay for cortex; handles incoming and outgoing signals---motor controls to muscles and glands Term Hypothalamus Definition Part of brain responsible for regulating basic biological needs; hunger, thirst, temperature control Term Pituitary Gland Definition "Master" gland that regulates other endocrine glands----secretes growth hormones Term Hippocampus Definition Part of limbic system involved in learning and memory Term Pons Definition Part of brain involved in sleep and arousal Term Medulla Definition Part of brain responsible for regulating largely unconscious functions such as breathing and circulation---controls reflexes; vomiting, coughing, sneazing Term Reticular Formation Definition Group of fibers that carry stimulation related to sleep and arousal through brainstem Term Spinal Cord Definition Responsible for transmitting information between the brain and the rest of the body; handles simple reflexes as well Term Cerebellum Definition Structure that coordinates fine muscle movement and balance. Term Amygdala Definition Part of limbic system involved in emotion and aggression Term Sensory Neuron Definition Recieve info. from sensory receptors Term Interneuron Definition transfers and interprets impulses between neurons Term Motor Neuron Definition sends impulses to muscles and glands Term Dendrite Definition Part of neuron that recieves info. Term Soma Definition Part of neuron that integrates info. from dendrites---decides wether or not to fire neural impulses Term Axon Definition Transmits messages to terminal buttons Term Terminal Buttons Definition end of Axon that secretes neurotransmitters in response to impulse. Term Neurotransmitter Definition Chemical messenger that acts within the synapse Term Synapse Definition point at which the neurons interconnect Term Myelin sheath Definition Insulation----speeds up transmission in axon Term Glial Cells Definition Produce myelin sheath, they also provide scaffolding for neurons. There are many more glial cells than neurons 10:1 Term Reuptake Definition process when neurotransmitters are pumped back into the transmitting neuron, otherwise they are broken up by enzymes Term Glutamate Definition main excitatory neurotransmitter in the CNS Term GABA Definition the most common inhibitory neurotransmitter. too much->unmotivated and sluggish; too little->anxiety and epilepsy Term Acetylchlorine Definition neurotransmitter that facilitates some kinds of learning and memory. messenger for motorneurons too, controls muscle contraction. too much->tremors; too little->anxiety and epilepsy Term Norepinephrine Definition neurotransmitter that coincides with heart rate, vigilance, stress, and mood. too much->jittery; too little->unmotivated and sluggish Term Endorphines Definition neurotransmitter that creates pleasure, reduces pain, and influences emotion.too much->feel no pain Term Dopamine Definition neurotransmitter that influences movement, learning, and attention. too much->schizophrenia; too little->parkinson's Term Seratonin Definition neurotransmitters that regulate mood, hunger, sleep, and arousal. too much-> always sleepy; too little->OCD depression, anxiety Term Agonist Definition Drug taht increases the synthesis or release of neurotransmitters; mimics neurontransmitters by fitting into receptors; inhibits reuptake; inhibits the enzymes that break them down. Term Antagonist Definition Drug that interfers with the release of neurotransmitters;occupies and blocks receptors; inhibits the affects of agonist drugs
