1The major coordinating system of the body is the [blank_start]nervous system[blank_end].
- Anervous system
2The major functional unit of the nervous system is the:
- ANeuron
- BBrain
- CNeuroglia
- DAxon
3Axons cannot regenerate in the peripheral nervous system
- ATrue
- BFalse
4The nervous system is divided into the [blank_start]central[blank_end] nervous system and the [blank_start]peripheral[blank_end] nervous system.
- Acentral
- Bperipheral
5The peripheral nervous system is composed of [blank_start]cranial[blank_end] nerves (originate directly from the brain) and [blank_start]spinal[blank_end] nerves (emerge from the spinal cord).
- Acranial
- Bspinal
6The peripheral nervous system is divided into the
- ASympathetic and parasympathetic nervous system
- BCentral and peripheral nervous system
- Cafferent and efferent nervous system
- Dautonomic and somatic nervous system
- Enone of the above
7Afferent nerves conduct impulses towards the central nervous system
- ATrue
- BFalse
8Efferent nerves are also referred to as sensory nerves.
- ATrue
- BFalse
9The two cell types in the nervous system are [blank_start]neurons[blank_end] and [blank_start]neuroglia[blank_end].
- Aneurons
- Bneuroglia
10Neuroglia produce the blood brain barrier.
- ATrue
- BFalse
11Neuroglia provide several function and structural supports to neurons. Place a check beside the functions neuroglia provide.
- AProduce the blood brain barrier
- BProduce myelin sheaths
- CConduct action potentials
- DBuffer ion and neurotransmitter concentrations
- EImmune response of the nervous system
- FModulate growth of developing neurons
- GModulate effectiveness of neural communication by monitoring electrical activity of neurons
- HRelease calcium
- IRelease sodium
12Neurons reproduce in the central nervous system.
- ATrue
- BFalse
13Neurons communicate via [blank_start]action potentials[blank_end].
- Aaction potentials
14The cell body manufactures proteins for cell function.
- ATrue
- BFalse
15The sodium/potassium pump brings sodium into the cell and potassium out of the cell.
- ATrue
- BFalse
16Label the action potential events.
- AResting Membrane Potential
- BDepolarization
- CAfter hyperpolarization
- DNa+ channels close, K+ channels open
- EK+ channels close, Na+ channels open
- FThreshold
- GRepolarization
17The four events in an action potential, in order, are:
1) [blank_start]Initiation[blank_end]
2) [blank_start]Depolarization[blank_end]
3) [blank_start]Repolarization[blank_end]
4) [blank_start]Refractory Period[blank_end]- AInitiation
- BFiring
- CDepolarization
- DExcitation
- ERepolarization
- FInhibition
- GRefractory Period
- HPositive period
18During the absolute refractory period, it is impossible to generate a second action potential because
- AThe cell is already depolarized past the threshold
- BThe cell membrane is too negative to reach the threshold
- CThere is not enough K+ in the cell
- DIn order to have summation reach threshold, you need more time
19Temporal summation is
- AInput from multiple synapses all at the same time
- BInput from a single synapse over time
20The process of an action potential being conducted along the length of an axon and by 'jumping' from one Node of Ranvier to the next is called [blank_start]saltatory conduction[blank_end].
- Asaltatory conduction
