Question

question 16 1 pts the more muscle fibers contracting at the same time, the stronger the contraction of the entire muscle. the number of muscle fibers contracting depends on how many motor units are conducted. inactivated. recruited. retained. question 17 1 pts which subtype of fibrous joints is found only in the skull? suture syndesmoses gomphoses synovial question 18 1 pts which structure allows the electrical signals to travel along the sarcolemma and move deeper into the cell? myosin actin transverse tubule sarcoplasm

Explanation:

• Question 16: The number of muscle - fibers contracting depends on the recruitment of motor units. When more motor units are recruited, more muscle fibers contract, leading to a stronger muscle contraction.
• Question 17: Sutures are a subtype of fibrous joints that are found only in the skull. They are immovable joints that hold the skull bones together.
• Question 18: Transverse tubules (T - tubules) allow electrical signals to travel along the sarcolemma and move deeper into the muscle cell, facilitating the synchronized contraction of muscle fibers.

Answer:

• Question 16: C. recruited
• Question 17: A. suture
• Question 18: C. transverse tubule
