Knee & Hip Flexion

The given answer, "Hip Ad-ductors," is correct because the muscles listed, including Adductor Brevis, Pectinus, Adductor longus, Adductor magnus, and Gracilis, are all hip adductor muscles. These muscles are responsible for bringing the thigh towards the midline of the body, or in other words, moving the leg inward. Therefore, they are correctly classified as hip adductors.

The rectus femoris, vastus medialis, vastus lateralis, and vastus intermedius are all muscles located in the thigh. These muscles are responsible for extending the knee joint, which means they help straighten the leg. Therefore, they are correctly classified as knee extensors.

The given correct answer is "Hip Extensors". The muscles listed in the question, including Biceps Femoris (LH), Glutus Maximus, Semitendinosus, and Semimembranosus, are all muscles that contribute to hip extension. Hip extension refers to the movement of the hip joint where the leg moves backward, away from the body or extends behind the body. These muscles work together to perform this action, allowing us to move our leg backward or extend it behind us.

The rectus femoris, sartorius, and iliopsoas are all muscles that contribute to hip flexion. Hip flexion refers to the movement of bringing the thigh towards the abdomen or bending at the hip joint. These muscles work together to flex the hip joint and allow for movements such as lifting the leg or bringing the knee towards the chest. Therefore, the correct answer is "Hip flexors."

The correct answer is Knee Flexors because the muscles mentioned in the question (Semitendinosus, Semimembranosus, Biceps Femoris) are all muscles that are responsible for flexing the knee joint. These muscles work together to bend the knee and bring the lower leg towards the back of the thigh.

The correct answer is Hip AB-ductors. The gluteus medius and tensor fascia latae are both muscles that are responsible for hip abduction. Hip abduction refers to the movement of the leg away from the midline of the body. These muscles work together to stabilize the pelvis and control the movement of the leg during activities such as walking, running, and jumping.

The muscles listed, including the piriformis, gemelli, obturators, and quadratus femoris, are all responsible for hip external rotation. These muscles work together to rotate the hip joint outward, away from the midline of the body. Therefore, the correct answer is "Hip external rotators."

The gluteus minimus is a muscle located in the hip region. Its primary function is to internally rotate the hip joint. This means that when the gluteus minimus contracts, it causes the thigh bone to rotate inward. Therefore, the correct answer is "Hip Internal rotators."
