Which one of these is true

Wave summation= when the impulses arrive at different places on the neurone at the same time

Tetanic contraction= single twitches and not sustainable

Spatial summation= when the impulses arrive at the same time but at different places on the neurone

Tetanic contraction= a weak contraction that is sustainable and links with Spatial Summation
