Innere Hüftmuskulatur

The video tutorial provides an in-depth look at the inner hip muscles, focusing on the iliacus, psoas major, and psoas minor. It explains the anatomy, origins, and functions of these muscles, highlighting the iliopsoas as a key flexor in the hip joint. The tutorial also covers the lumbar plexus and the role of the psoas minor in hip stabilization.

Which muscles are often grouped together as the iliopsoas muscle?

• Psoas minor and adductors

• Iliacus and psoas major

• Iliacus and adductors

What is the primary function of the iliopsoas muscle?

• Flexion of the elbow

• Rotation of the shoulder

• Flexion of the hip joint

• Extension of the knee

Where do the iliacus and psoas major muscles attach?

• Greater trochanter of the femur

• Lesser trochanter of the femur

• Acetabulum of the pelvis

• Ischial tuberosity

Which nerve is associated with the iliopsoas muscle?

• Tibial nerve

• Obturator nerve

• Rotation of the lumbar spine

• Flexion of the knee

• Stabilization of the pelvis and hip joint

• Extension of the hip joint

Which structure does the psoas minor muscle attach to?

• Greater trochanter

• Acetabulum

• Eminentia Ileo Pubica
