| Question | Answer |
|---|---|
| Name 5 things that can be found in a synaps | Ions channel, synaptic vesicles calcium ions, postsynaptic membrane, synaptic cleft |
| Neurotransmitters are released at the | axon terminal |
| the rough ER of the cell | nissl bodies |
| Conducts impulses toward the nerve cell body | dendrites |
| conducts impulsed away from the nerve cell body | Axon |
| Numerous nerve impulses arriving at a synapse at closely timed intervals exert a cumulative effect | Temporal summation |
| an insufficient stimulus | subthreshould stimulus |
| any stmulus below this intensity will result in no response in a neuron | Theshold stimulus |
| Auditory area is in the | Temporal lobe |
| primary sensory cortex is in the | parietal lobe |
| Somatic motor cortex is in the | Frontal lobe |
| Motor speech area is in the | Frontal lobe |
| Premotor area is in the | Frontal lobe |
| Visual area is in the | Occipital lob |
| Language/speech comprehension area is in the | Temporal lobe |
| Taste (gustatory) area is in the | Parietal lobe |
| Seat of intelligence, abstract reasoning is in the | Frontal lobe |
| Ciliated CNS neurologia that play an active role in moving the cerebrospinal fluid are called | ependymal cells |
| The sheath of Schwann is also called the | neurolemma |
| An excitatory neurotransmitter secredted by motor neurons innervating skeletal muscle is | acetylcholine |
| The period after an initial stimulus when a neuron is not sensitive to another stimujlus is the | refractory period |
| The part of a meuron that conducts impulses away from its cell body is called | axon |
| the role of acetylcholinesterase is to | destroy ACh a bried perion after its release by the axonal endings |
| collections of nerve cell bodies outside the central nervous sysytem are called | ganglia |
| a neuron that has as its primary function the job of connecting other neurons is | association neuron (inter neuron) |
| Which of these ions is actively transported through the cell membrane to establish a restion potential | Na |
| an action potential | is essential for impulse propagation |
| Meuroglia that control the chemical environment around neurons by buffering potassium and recapturing meurotransmitters are | astrocytes |
| An inhibitory postsynaptic potential (IPSP) is associated with | hyperpolarization |
| The brain stem consists of the | midbrain medulla and pons |
| Spinocerebellar tracts | carry proprioceptive inputs to the cerebellum |
| The subarachnoid space lies between what two layers of meninges | arachnoid and pia |
| the cedrbrospinal fluid is pormed mostly by | the choroid plexuses |
| the central sulcus separates which lobes | frontal from parietal |
| the hypothalamus | is the thermostat of the body since is regulates temperature |
| An individual accidentally transected the spinal cord between T1 and L1. Ths would result in | paraplegia |
| Two terms for trhe massive mototr tracts serving voluntary movement are | pyramidal and corticospinal |
| kAn individuyal who could trace a picture of a bicycle withe his or her finger byt coule not recognize it as a bicycle is most likelyt to have sustained damage to the | visual association area |
| name three structures of the limbic system | hippocampus, cigulate gyrus, and amygdaloid necleus |
| Normal cerebrospinal fluid contains | flucose, potassium, protein |
| Huntingtons's disease | has symptoms that are the opposite of parkinson's disease |
| Declarative memory is | the ability to learn specific information |
| White matter (myelinated fibers) is found in what locations | copus callosum, corticospinal tracts, outer surface of the spinal cord |
| Loss of ability to perform skilled motor activities such as piana playing with no paralysis or weakness is specific muscles might suggest damage to the | premotor cortex |
| what is the cauda equina and why is it given this name | nerves exiting the spinal cord, looks like a horses tail |
