Musculus pectineus

The video tutorial covers the six adductors of the hip joint, focusing on their origin, innervation, and functions. The pectineus muscle is highlighted for its unique origin and dual innervation by the obturatory and femoral nerves. The adductors are essential for movements like adduction, external rotation, and slight flexion of the hip joint, as well as stabilizing the pelvis during walking and standing.

What is the origin of the pectineus muscle?

• Obturatory canal

• Pecten Ossis pubes

• Linea aspera

• Trochanter minor

Which nerve is primarily responsible for the innovation of all hip joint adductors?

• Lumbar nerve

• Obturatory nerve

• Sciatic nerve

• Femoral nerve

What additional role does the pectineus muscle have in terms of nerve representation?

• It is also represented by the obturatory nerve.

• It is also represented by the lumbar nerve.

• It is also represented by the sciatic nerve.

• It is also represented by the femoral nerve.

Which of the following is NOT a function of the hip joint adductors?

• Stabilization of the pelvis

• Flexion of the knee

• External rotation

• Adduction

Why are the hip joint adductors important when walking or standing?

• They aid in ankle rotation.

• They assist in shoulder movement.

• They stabilize the pelvis.

• They help in knee flexion.
