Which of the following statements best distinguishes between tetanus and treppe?
A) Tetanus is due to repeated stimulation of the muscle; treppe is the result of a single long stimulation of the muscle.
B) Tetanus occurs when stimulation of muscle occurs frequently with little to no relaxation between stimuli; treppe occurs when stimulation of muscle occurs frequently, but complete relaxation occurs between stimuli.
C) Tetanus only occurs in laboratory settings, but treppe occurs all the time in normal muscle activity.
D) Tetanus involves increasing the number of motor units stimulated simultaneously; whereas, treppe involves the repeated stimulation of a single muscle fiber.
Tetanus
A bacterial infection characterized by muscle spasms, often starting in the jaw and then spreading to other parts of the body.
Treppe
A phenomenon observed in muscle physiology whereby the successive contractions become increasingly stronger following a series of stimuli of the same strength.
Motor Units
A single motor neuron and all the muscle fibers it innervates, functioning as a single unit.

Final Answer :
B
Explanation :
Tetanus and treppe both involve muscle responses to stimuli, but they differ in the pattern of stimulation and muscle response. Tetanus occurs with rapid, frequent stimulation that doesn't allow the muscle to relax fully between stimuli, leading to a sustained contraction. Treppe, on the other hand, occurs with stimuli that are frequent enough to cause successive contractions but allow for complete relaxation between them, resulting in gradually increasing strength of contraction.
