A. Posterior TibialisExplanation
The correct answer is Posterior Tibialis because it is the muscle located on the posterior side of the tibia bone. It originates from the back of the shin bone and inserts into the bones of the foot. This muscle is responsible for inversion and plantar flexion of the foot, as well as supporting the arch of the foot.Rate this question:

- E.
Eversion of the foot
Correct Answer(s)
B. Accelerate plantarflexion
D. Inversion of the footExplanation
The concentric function of the muscle shown above is to accelerate plantarflexion and inversion of the foot. This means that when the muscle contracts, it helps to point the foot downwards (plantarflexion) and turn the sole of the foot inward (inversion).Rate this question:

(All of the above)
Correct Answer(s)
A. Eccentrically decelerate eversion
C. Eccentrically decelerate plantarflexion
D. Isometrically Stabilize the arch of the footExplanation
The muscle shown in the question is responsible for eccentrically decelerating eversion and plantarflexion, as well as isometrically stabilizing the arch of the foot. This means that the muscle helps to control the movement of the foot during these actions, preventing them from occurring too quickly or forcefully. Additionally, the muscle provides stability to the arch of the foot, helping to maintain its shape and support the body's weight during activities. Therefore, all of the given options are correct.Rate this question:

- E.
(None of the Above)
Correct Answer
D. Isometrically stabilse the arch of the footExplanation
The correct answer is "Isometrically stabilize the arch of the foot." This means that the muscle shown in the question is responsible for maintaining the stability of the arch of the foot without any movement. It does not decelerate plantarflexion or inversion of the foot, and it does not stabilize the foot and ankle complex.Rate this question:

Eccentrically decelerates ankle dorsiflexion
- B.
Eccentrically decelerates inversion of the foot
- C.
Eccentrically decelerates dorsiflexion
- D.
Isometrically stabilizes the foot and ankle complex
- E.
Eccentrically decelerates eversion of the foot
Correct Answer(s)
B. Eccentrically decelerates inversion of the foot
C. Eccentrically decelerates dorsiflexion
E. Eccentrically decelerates eversion of the footExplanation
The muscle shown above is involved in eccentrically decelerating three different movements of the foot: inversion, dorsiflexion, and eversion. Eccentric contraction occurs when a muscle lengthens while under tension, acting as a brake to slow down a movement. In this case, the muscle is working to slow down the movements of inversion (turning the foot inward), dorsiflexion (bringing the foot upward), and eversion (turning the foot outward). This muscle also isometrically stabilizes the foot and ankle complex, meaning it contracts to maintain stability and prevent excessive movement in the joint.Rate this question:

(None of the Above)
Correct Answer
B. SoleusExplanation
The correct answer is Soleus. The muscle shown in the image is the soleus muscle. It is located in the lower leg and is one of the muscles that make up the calf. The soleus muscle works together with the gastrocnemius muscle to help flex the foot and provide power for movements such as walking, running, and jumping.Rate this question:

The Biceps Femoris Long Head, Semimembranosus, and Semitendinosus muscles all have the integrated function of decelerating hip flexion. This means that they help to slow down or control the movement of the hip joint when it is being flexed. On the other hand, the Biceps Femoris Short Head does not have this function, suggesting that it is not involved in decelerating hip flexion.Rate this question:
- 22.
What integrated eccentrical function does the Biceps Femoris Long Head and Short Head have in common?
Correct Answer(s)
Decelerates tibial internal rotationExplanation
The Biceps Femoris Long Head and Short Head both have the integrated eccentric function of decelerating tibial internal rotation.

Correct Answer
C. 4Explanation
The gluteals, which are part of the hip musculature, are divided into four sections. These sections include the gluteus maximus, gluteus medius, gluteus minimus, and tensor fasciae latae. Each section has its own specific functions and plays a role in hip movement and stability.Rate this question:

E. (All of the Above)Explanation
The gluteals are a group of muscles located in the hip region. The gluteus maximus is the largest muscle in this group and is responsible for hip extension. The gluteus medius, both posterior and anterior portions, are smaller muscles that assist with hip abduction and rotation. The gluteus minimus is also a smaller muscle that assists with hip abduction. Therefore, all of the options listed - gluteus maximus, gluteus medius (posterior), gluteus minimus, and gluteus medius (anterior) - are part of the gluteals.Rate this question:

D. Integrated Isometrical stabilization of the lumbo-pelvic-hip complexExplanation
The gluteal muscles, including the gluteus maximus, medius, and minimus, perform the function of integrated isometrical stabilization of the lumbo-pelvic-hip complex. This means that they work together to provide stability and support to the lower back, pelvis, and hip joints during movement. They help maintain proper alignment and prevent excessive movement or rotation of these areas, which can help prevent injuries and improve overall movement efficiency.Rate this question:

B. Concentrically accelerates hip extension and external rotation
D. Eccentrically decelerates hip flexion and internal rotation
E. Decelerates tibial internal rotation via the iliotibial bandExplanation
The Gluteus Maximus is responsible for concentrically accelerating hip extension and external rotation, meaning it helps to move the hip joint backward and rotate it outward. It also eccentrically decelerates hip flexion and internal rotation, meaning it helps to slow down the movement of the hip joint as it bends forward and rotates inward. Additionally, the Gluteus Maximus plays a role in decelerating tibial internal rotation by using the iliotibial band to prevent excessive inward rotation of the shin bone.Rate this question:
-
- 36.
The Gluteus Minimus performs the same functions as the (blank).
Correct Answer(s)
Explanation
The Gluteus Minimus performs the same functions as the Gluteus Medius. Both muscles are located in the buttocks and are responsible for abduction, or moving the leg away from the midline of the body. They also assist in stabilizing the pelvis during walking or standing on one leg.Rate this question:
