Question

which of the following is a muscle contraction cycle in which muscle tension increases to its maximum due to successive stimulations with no time for relaxation?

a.) hypertonia
b.) complete tetanus
c.) twitch
d.) incomplete tetanus

Explanation:

Analyze the physiological definitions of the options

• Hypertonia: An abnormal increase in muscle tension and a reduced ability of a muscle to stretch, typically caused by injury to motor pathways in the central nervous system.
• Complete Tetanus: A smooth, sustained muscle contraction that occurs when the frequency of stimulation is so high that the muscle does not have time to relax at all between stimuli, leading to maximum tension.
• Twitch: A single, rapid contraction and relaxation cycle of a muscle fiber in response to a single stimulus.
• Incomplete Tetanus: A state of sustained but oscillating muscle contraction where the muscle undergoes rapid cycles of contraction followed by partial relaxation between successive stimuli.

Match the question criteria to the correct term

• The question describes a cycle where muscle tension increases to its maximum due to successive stimulations with no time for relaxation.
• This matches the definition of Complete Tetanus (also known as fused tetanus).

Answer:

• a.) Hypertonia
• b.) Complete Tetanus (Correct answer)
• c.) Twitch
• d.) Incomplete Tetanus
