|
The membrane of the neuron suddenly becomes more permeable to ______ than to potassium.
|
Sodium
|
|
|
Whats the deference between Depolorization ad Hyperpolarization?
|
Hyperpolarization means that the neuron is much more permeable to potassium then usual. And depolarization is Excess positive ions are found inside the nerve cell.
|
|
|
Explain the synapse.
|
The synapse is a space between a neurons axon and its target, also can be called the "Synaptic Cleft."
|
|
|
After acetylcholine has moved across the membrane it needs to be?
|
Re-absorbed, or broken down by cholinesterase.
|
|
|
Inhibitory transmitters cause k+ to?
|
Leak out hyperpolorizing the membrane.
|
|
|
What does "summation" mean?
|
The sum effect of all neurotransmitters acting on the neuron.
|
|
|
Which cells make up the myelin sheath?
|
Schwann cells
|
|
|
What is the Neurilemma?
|
Is a protective membrane that helps in regeneration of a neuron not found in grey matter
|
|
|
All paths must incliude 3 seperate things, they are?
|
Reception
Transmission Processing |
|
|
Whats is the difference between depolarization and repolarization?
|
Depolaization is when the neuron is stimulated enough to cause Na+ gates to open, the other is for sodium.
|
|
|
Explain receptions?
|
Reception refers to dendrites being stimulated by an enviroment factor and starting an impulse.
|
|
|
Explain the all or none theory?
|
The neuron either responds fully or not at all.
|
|
|
Explain the synapse.
|
The synapse is a space between a neurons axon and its target, also can be called the "Synaptic Cleft."
