| 4813515259 | Neuron | 1) a nerve cell; the basic building block of the nervous system 2) a nerve cell |  | 0 |
| 4813518850 | Sensory Nerurons | 1) neurons that carry incoming information from the sensory receptors to the brain and spinal cord. 2) sends information to brain | 1 | |
| 4813522768 | Motor Neurons | 1) neurons that carry outgoing information from the brain and spinal cord to the muscles and glands. 2) controls movement | 2 | |
| 4813524251 | Interneurons | 1) neurons within the brain and spinal cord that communicate internally and intervene between the sensory inputs and motor outputs. 2) controls decisions | 3 | |
| 4813524914 | Dendrite | 1) the bushy, branching extensions of a neuron that receive messages and conduct impulses toward the cell body. 2) part of neuron that gets messages and starts the next signal |  | 4 |
| 4813527155 | Axon | 1) the extension of a neuron, ending in branching terminal fibers, through which messages pass to other neurons or to muscles or glands 2) part of neuron that sends electricity to branches |  | 5 |
| 4813528720 | Myelin Sheath | 1) a layer of fatty tissue segmentally encasing the fibers of many neurons; enables vastly greater transmission speed of neural impulses as the impulse hops from one node to the next 2) covers axons |  | 6 |
| 4813533884 | Action Potential | 1) a neural impulse; a brief electrical charge that travels down an axon. 2) firing of neuron | 7 | |
| 4813537608 | Threshold | 1) a level of stimulation required to trigger a neural impulse. 2) energy that starts it but it cannot be stopped | 8 | |
| 4813538599 | Synapse | 1) the junction between the axon tip of the sending neuron and the dendrite or cell body of the receiving neuron. The tiny gap at this junction is called the synaptic gap or synaptic cleft. 2) space between neurons |  | 9 |
| 4813540922 | Neurotransmitters | 1) chemical messengers that cross the synaptic gaps between neurons. When released by the sending neuron, neurotransmitters travel across the synapse and bind to receptor sites on the receiving neuron, thereby influencing whether that neuron will generate a neural impulse. 2) chemicals used to message other neurons |  | 10 |
| 4813553370 | Reuptake | 1) a neurotransmitter's reabsorption by the sending neuron. 2) a neurotransmitters going back to original neuron | 11 | |
| 4813605247 | Endorphins | 1) "morphine within" - natural, opiatelike neurotransmitters linked to pain control and pleasure 2) chemical that controls pain and pleasure | 12 | |
| 4813612713 | Nervous System | 1) the body's speedy, electrochemical communication network, consisting of all the nerve cells of the peripheral and central nervous systems. 2) a fast network of neurons | 13 | |
| 4813614446 | Central nervous system | 1) the brain and spinal cord 2) brain and backbones |  | 14 |
| 4813616619 | Peripheral Nervous System | 1) the sensory and motor neurons that connect the central nervous system (CNS) to the rest of the body. 2) neurons branching off the spinal cord |  | 15 |
| 4813617805 | Nerves | 1) bundled axons that form neural "cables" connecting the central nervous system with muscles, glands, and sense organs 2) a group of neurons | 16 | |
| 4813619808 | somatic nervous system | 1) the division of the peripheral nervous system that controls the body's skeletal muscles. Also called the skeletal nervous system 2) controls voluntary movement like waving your hand |  | 17 |
| 4813621428 | Autonomic nervous system | 1) the part of the peripheral nervous system that controls the glands and the muscles of the internal organs (such as the heart). Its sympathetic division arouses; its parasympathetic division calms. 2) controls involuntary movements like heart beats and digestion |  | 18 |
| 4813644473 | Sympathetic Nervous System | 1) the division of the autonomic nervous system that arouses the body, mobilizing its energy in stressful situations 2) part of nervous system that gives us energy to fight or flight |  | 19 |
| 4813625722 | reflex | 1) a simple, autonomic response to a sensory stimulus such as the knee-jerk response. 2) involuntary response to something | 20 | |
| 4813623441 | Parasympathetic Nervous System | 1) the division of the autonomic nervous system that calms the body, conserving its energy. 2) part of nervous system that calms you down |  | 21 |
| 4813626983 | endocrine system | 1) the body's "slow" chemical communication system; a set of glands that secrete hormones into the bloodstream. 2) a slow system using hormones to communicate to each other |  | 22 |
| 4813628745 | Hormones | 1) chemical messengers that are manufactured by the endocrine glands, travel through the bloodstream, and affect other tissues 2) messengers of the endocrine system | 23 | |
| 4813634807 | Adrenal Glands | 1) a pair of endocrine glands that sit just above the kidneys and secrete hormones (epinephrine and norepinephrine) that help arouse the body in times of stress. 2) glands that produces adrenaline |  | 24 |
| 4813630599 | Pituitary Gland | 1) the endocrine system's most influential gland. Under the influence of the hypothalamus, the pituitary regulates growth and controls other endocrine glands. 2) the master gland of the endocrine system |  | 25 |
| 4843538719 | Biological Psychology | 1) a branch of psychology that studies the links between biological (including neuroscience and behavior genetics) and psychological processes. 2) study of human body in psychology (what does the body do) | 26 |
