Temporal summation and spatial summa-Description of tetany

Question

Write down the differentiation between temporal summation and spatial summation of the muscle fibers? Give a brief description of tetany?

Answer 1

Spatial summation is recruiting of newest muscle fibers to raise the muscle strength. Temporal summation takes place when a muscle fiber is incessantly excited to contract without being capable to conclude relaxation.

Permanence of a muscle fiber under a constant state of the contraction by temporal summation is recognized as tetany (e.g., clinical situation of patients contaminated by toxin of tetanus bacteria). Tetany ends when all accessible energy for contraction is spent or when stimulus ceases.
