Question:
- Which type of contraction allows a muscle to produce tension without changing the angle of a skeletal joint or moving a load?
- A. All of the muscle fibers in a specific muscle
- B. A motor neuron and the muscle fibers it innervates
- C. The sarcomere and its associated sarcolemma
- D. A functional group of sarcomeres
- E. A packet of actin and myosin microfilaments
Answer
C. The sarcomere and its associated sarcolemma
In general this falls under isometric type of contraction where the type of strength training in which the joint angle and muscle length do not change during contraction
Explanation
In general, the type of contraction can be categorized as an isometric contraction which is known to occur when the muscle produces tension without changing the angle of a skeletal joint. in addition, this type of contraction involve the sarcomere shortening and increasing muscle tension and not moving load because the force produced cannot overcome the resistance that is usually provided by the load
