Nervous System 10 Jeopardy Template

Basic Structure and Function	Nervous Tissue	Function	Action Potential	Communication Between Neurons
100 neurons and glial cells What are two basic types of cells in CNS and PNS?	100 from dendrites, across the cell body and down the axon What direction does an action potential move along a neuron?	100 graded potential What is a change in the membrane potential that varies in size, depending on the size of the stimulus that elicits it?	100 a ligand (neurotransmitter) What binds to extracellular region of ligand-gated channel?	100 depolarizing and hyperpolarizing What are the two kinds of graded potentials?
200 dendrites What part of neuron receives most of the input from other neurons?	200 insulation and myelination What functions do oligodendrocytes and Schwann cells have in common?	200 threshold What is the membrane voltage at which an action potential is initiated?	200 large negative proteins, chloride ions and nucleic acids inside cell What keeps a cell membrane negatively polarized?	200 unipolar cell What type of neuron does a generator potential occur in?
300 ganglion What is a cluster of neurons in PNS called?	300 immune surveillance and phagocytosis What is the function of a microglia in CNS?	300 action potential What is a change in voltage of a cell membrane in response to a stimulus that results in transmission of an electrical signal (unique to neurons and muscle fibers)?	300 becomes depolarized (membrane potential moves toward zero) What happens to cell membrane potential as Na+ moves through it?	300 temporal summation What kind of summation is a combination of graded potentials at same location from one input?
400 gray matter What region in brain contains cell bodies, dendrites and unmyelinated axons?	400 line each ventricle in heart Where can ependymal cells be found?	400 a lower motor neuron What does an upper motor neuron contracts?	400 absolute refractory period and relative refractory period What are the two phases of the refractory period?	400 metabolic changes What kind of changes does a metabotropic receptor cause in a cell?
500 somatic nervous system (SNS) What functional division of brain is responsible for conscious perception and voluntary motor responses?	500 myelin sheath What facilitates transmission of electrical signals along the axon?	500 causes contraction of a targeted skeletal muscle What is the function of a lower motor neuron?	500 a myelinated axon What kind of axon does a saltatory conduction travel along?	500 presynaptic element, neurotransmitter, synaptic cleft, receptor proteins, postsynaptic element and neurotransmitter elimination or re-uptake What do all synapses have in common?
