neural components Flashcards
1
Q
depolarization
A
-membrane potential changes
-muscle contracts
2
Q
repolarization
A
-muscle relaxes
3
Q
refectory period
A
-the brain will be able to perceive nerve impulses as separated events since there is a time lag between them
4
Q
summation
A
contraction before previous contraction relaxed
5
Q
tetany
A
If the frequency of these contractions increases to the point where maximum tension is generated and no relaxation is observed
6
Q
doublets
A
firing initially fast rates
