Question

The force of muscle contraction is controlled by multiple motor unit summation or recruitment.

True / False

Answer 1

The correct answer is - true.

Step-by-step explanation:

Muscle contraction is essential for the all type of the movements in the body which is controlled by the two proteins namely, tropomyosin and troponin on the actin filament actions.

The motor neurons that brings the signals from the CNS transmit is signal in the form of chemicals at neuromuscular junction. It involves the motor neurons in multiple that brings the signals by their recruitment or summation.

Thus, the correct answer is - true.

Answer 2

True.

Step-by-step explanation:

Muscle is one of the mist important tissue of our body as it helps in the coordinating and body movement. Three different types of muscle are cardiac muscle, smooth muscle and skeletal muscle.

The muscle contraction result in the particular movement of the body parts. The muscle contraction requires different sarcomere unit and proteins like actin and myosin. The different motor units are involved in the process of summation of the muscle contraction.

Thus, the correct answer is true.
