Which types by activity muscle fiber type contract at different speeds?
Correct Answer
A. Skeletal muscle
Explanation
Skeletal muscle fibers contract at different speeds. This is because skeletal muscles are responsible for voluntary movements and need to be able to generate quick and powerful contractions. They contain two main types of muscle fibers: slow-twitch (Type I) fibers and fast-twitch (Type II) fibers. Slow-twitch fibers contract slowly and are fatigue-resistant, making them suitable for endurance activities. Fast-twitch fibers contract rapidly and generate more force, but they fatigue quickly. This allows skeletal muscles to adapt to different activity levels and perform a wide range of movements efficiently.
2.
Which muscle is this?
Correct Answer
B. Gluteus maximus
Explanation
The correct answer is Gluteus maximus. The gluteus maximus is the largest muscle in the buttocks and is responsible for hip extension, thigh abduction, and thigh external rotation. It is an important muscle for activities such as walking, running, and climbing stairs. The other options, gluteus minimus and gluteus medius, are also muscles in the buttocks but they have different functions.
3.
And this one?
Correct Answer
C. Gluteus minimus
Explanation
The gluteus minimus is a small muscle located in the buttocks region. It is responsible for abduction and medial rotation of the hip joint. The other options, gluteus medius and gluteus maximus, are also muscles in the buttocks, but they have different functions. The gluteus medius is involved in abduction and stabilization of the hip, while the gluteus maximus is the largest muscle in the buttocks and is responsible for hip extension and external rotation. Therefore, the correct answer is gluteus minimus.
