Question

question 7 1 pts this arrangement of muscle fascicles tends to be triangular in shape. the pectoralis major is an example of a muscle with this type of muscle fascicle arrangement. parallel bipennate convergent unipennate circular question 8 1 pts the innermost muscle of the abdominal wall is the internal oblique. external oblique. rectus abdominis. transverse abdominis. question 9 1 pts the continuous low level of sustained contraction maintained by all skeletal muscles is muscle summation. posture. tone. tetanus.

Explanation:

• Question 7: Convergent muscle fascicles are triangular - shaped with fascicles converging to a single tendon. Pectoralis major has this arrangement.
• Question 8: The innermost muscle of the abdominal wall is the transverse abdominis. The other muscles (internal oblique, external oblique, rectus abdominis) are more superficial or in different layers.
• Question 9: Muscle tone is the continuous low - level of sustained contraction maintained by all skeletal muscles. It helps in maintaining posture and keeping muscles ready for action.

Answer:

Question 7: C. convergent
Question 8: D. transverse abdominis
Question 9: C. tone
