Nervous System Overview
Division of the nervous system that consists of special senses that we are aware of.
Such as touch, taste, hear, smell, and see
what is somatic sensory division
where local potentials occur
** extra 100 points if you can tell me where action potentials are sent from
what is dendrites
** what is the trigger zone
Name the 2 neuroglia that are a part of the peripheral nervous system
what are
1) Satellite cells
2) schwann cells
neural circuit that requires 1 presynaptic neuron, and multiple postsynaptic neurons
diverging circuit
neuron shape that has no axon
what is anaxonial
this is the connection between an axon and a dendrite
Characteristic that describes local potentials as getting weaker as they get further away from the source
decremental
neuroglia that is responsible for moving around cerebrospinal fluid
what is ependymal cells
reverberating circuit
Division of the nervous system that is considered to be the fight or flight division.
**Extra 100 points if you can name what it is a subdivision of
**what is visceral motor division
out of,
- excitatory post synaptic potential
- inhibitory post synaptic potential
which one makes the neuron become more negative
IPSP
Tell me whether local and action potentials are excitatory or inhibitory
1) Action potentials
2) local potentials
1) excitatory
2) both
responsible for creating myelin
* extra 100 points if you can tell me the cell that cleans and organizes the nervous system
what is oligodendrocytes
** what is microglia
what is a collection of neurons that form a network for all emotions, images, and memory traces
engram ( memory)
Neurons that take information to the brain.
** extra 100 points if you can name whether it is efferent or afferent
* what is afferent
what is known as the chemical key for action potentials to flow down an axon
what is ligand gated channel
which phase of a refractory period can another action potential be sent, but it has to be extremely strong in order to occur
relative refractory period
responsible for covering the brains surface to monitor pH levels and regulating blood
what is astrocytes
what can be defined as making it easier for neurotransmitters to cross a synapse
synaptic potentiation
which disease of the nervous system is linked to decreased levels of acetylcholine
** extra 200 points if you can name the other disease and how it happens.
what is altzheimers
** Neurotransmitter dopamine is severely depleted causing rapid motor movements
during neural coding, quantitative information considers brightness, loudness, and intensity of your environment. Which characteristic makes more action potentials the more intense it gets
firing frequency
Summation where multiple stimuli are being sent down the same presynaptic neuron rapidly to reach the postsynaptic neuron
** extra 200 points to the team that can tell me the other type and how it works
temporal summation
** Spatial summation
- stimuli being sent down multiple presynaptic neurons reaching the postsynaptic neuron at the same time slowly
True or false, then correct it if false
The neuroglia that coils around axons acting as a multilayered myelin sheath sheath is a satellite cell.
false
schwann cell
which form of long term memory can be described as remembering motor skills and activities of daily living
