Each muscle is surrounded by a connective tissue sheath called the epimysium. ... Within the fasciculus, each individual muscle cell, called a muscle fiber, is surrounded by connective tissue called the endomysium. Skeletal muscle cells (fibers), like other body cells, are soft and fragile.
Answer:
The correct answer is C) Gluteus Maximus (GM)
Explanation:
Another word for the Gluteus Maximus Muscle is the buttock muscles.
The sprinter grabbed the back of his thigh because it starts right on top of the posterior end of the pelvis and extends almost midway into the thigh.
The functions of the Gluteus Maximus include but are not limited to:
- It keeps the leg straight at the hip;
- Most importantly, when the body stoops or bends over, it helps the body regain an upright erect position. It does this by (in conjunction with other muscles) pulling the pelvis backwards.
Because the sprinter injured the GM, he or she will be unable to resume upright position or flex his knee (which exerts pulling stress on the GM) without feeling a great deal of pain.
Cheers!
