Gemelli muscles (3D)

The video tutorial explores the jamelli muscles, focusing on their anatomy, innervation, and functions. It explains how these muscles contribute to hip joint movements, such as external rotation and abduction, and their role in stabilizing the hip. The tutorial also highlights the importance of these muscles in activities like walking and martial arts. Through a detailed examination of their origins, insertions, and nerve supply, viewers gain a comprehensive understanding of the jamelli muscles' role in maintaining hip joint health and function.

What is the primary role of the Jamelli muscles in martial arts?

• To increase strength

• To enhance flexibility

• To improve balance

• To aid in hip joint rotation

Where do the superior and inferior Jamelli muscles originate?

• From the ischial spine and ischial tuberosity

• From the femur and tibia

• From the sacrum and coccyx

• From the iliac crest and pubis

Which nerve innervates the superior Jamelli muscle?

• Femoral nerve

• Nerve to the quadratus femoris

• Nerve to the obturator internus

• Sciatic nerve

What is the primary function of the Jamelli muscles?

• Extension of the knee joint

• Flexion of the hip joint

• External rotation of the thigh

• Adduction of the arm

During which phase of walking do the Jamelli muscles play a crucial role?

• Toe-off phase

• Mid-stance phase

• Early swing phase

• Heel strike phase

How do the Jamelli muscles contribute to hip joint stability?

• By enhancing blood circulation

• By reducing muscle fatigue

• By increasing the range of motion

• By supporting the head of the femur within the acetabulum

What movement is described by the abduction of the flexed thigh?

• Rotation around the vertical axis

• Flexion of the knee

• Movement away from the midline of the body

• Movement towards the midline of the body
