In each blank, try to type in the
word that is missing. If you've
typed in the correct word, the
blank will turn green.
If your not sure what answer should be entered, press the space bar and the next missing letter will be displayed. When you are all done, you should look back over all your answers and review the ones in red. These ones in red are the ones which you needed help on. Question: Answer: an electrically excitable cell that processes and transmits information by and chemical signaling Question: Answer: The body of an organism, exclusive of the germ cells. Question: DendriteAnswer: fiber that conducts toward the cell body of the neuron Question: SynapseAnswer: the junction between two neurons (axon-to-dendrite) or between a neuron and a muscle; "nerve impulses cross a through the action of neurotransmitters" Question: neuronAnswer: A multipolar neuron is a type of neuron that possesses a single (usually long) axon and many , allowing for the integration of a great deal of information from other neurons. These dendritic branches can also emerge from the nerve cell body Question: Bipolar Answer: A cell is a type of neuron which has two extensions. Bipolar cells are specialized sensory neurons for the transmission of special senses. As such, they are part of the sensory pathways for smell, sight, taste, hearing and vestibular functions. Question: Unipolar Answer: A unipolar neuron is a type of neuron in which only one protoplasmic process (neurite) extends from the cell body. Most neurons are multipolar, generating dendrites and an axon. Question: Anaxonic Answer: A nervous system neuron that has many processes but no apparent axon. Question: Schwann Answer: any cell that covers the nerve fibers in the peripheral nervous system and forms the myelin Question: sheathAnswer: medullary sheath: a layer of myelin encasing (and ) the axons of medullated nerve fibers Question: Electrical Answer: called the electrostatic potential) at a point in space is electrical potential energy divided by charge that is associated with a static (time-invariant) field. Question: CurrentAnswer: a flow of electricity through a conductor; "the current was in amperes" Question: PolarizedAnswer: is a property of certain of waves that describes the orientation of their oscillations. Question: Answer: a neurochemical that transmits nerve impulses across a Question: Answer: a monoamine neurotransmitter found in the brain and essential for the normal functioning of the nervous system; as a drug (trade names Dopastat and Intropin) it is used to treat shock and hypotension Question: Answer: a neurotransmitter involved in e.g. and depression and memory Question: Somatic Answer: Any in which the effectors are skeletal muscles, eg, the patellar reflex, the flexor or withdrawal reflex, the crossed extensor reflex, the plantar reflex, the abdominal reflexes, etc. Question: reflexAnswer: Reflesxes within the organs Question: MeningesAnswer: meninx: a membrane (one of 3) that envelops the brain and cord Question: Dura Answer: the outermost (and toughest) of the 3 Question: Gray Answer: greyish nervous tissue containing cell as well as fibers; forms the cerebral cortex consisting of unmyelinated neurons Question: White Answer: whitish nervous tissue of the CNS consisting of and their myelin sheaths Question: CerebrumAnswer: anterior portion of the brain consisting of two ; dominant part of the brain in humans Question: CerebellumAnswer: a major of the vertebrate brain; situated above the medulla oblongata and beneath the cerebrum in humans Question: GyrusAnswer: a fold or elevation in the surface of the brain Question: Answer: (anatomy) any of the narrow grooves in an organ or tissue especially those that mark the convolutions on the of the brain Question: BrainstemAnswer: the part of the brain continuous with the spinal cord and comprising the medulla oblongata and pons and and parts of the hypothalamus Question: CortexAnswer: cerebral cortex: the layer of neurons (the grey matter) forming the cortex of the cerebrum Question: Blood-brain Answer: a mechanism that creates a barrier between brain tissues and circulating blood; serves to protect the central nervous system; "the brain was protected from the large molecules of the virus by the -brain barrier" Question: oblongataAnswer: lower or hindmost part of the ; continuous with spinal cord Question: ThalamusAnswer: large egg-shaped structures of grey matter that form the dorsal subdivision of the Question: HypothalamusAnswer: a basal part of the governing autonomic nervous system Question: lobeAnswer: that part of the cortex in either hemisphere of the brain lying in the back of the head Question: lobeAnswer: that part of the cerebral in either hemisphere of the brain lying below the crown of the head Question: lobeAnswer: that part of the cerebral in either hemisphere of the brain lying directly behind the forehead |
