Adductor Longus Muscle - Origin, insertion, innervation and function - Anatomy | Kenhub

Summary

In this tutorial by Matt from Kenhub, the anatomy and function of the adductor longus muscle are explored. As part of the inner hip musculature, the adductor longus plays a crucial role in adducting the hip joint and supporting flexion. Originating from the superior pubic ramus and inserting at the linea aspera, it is innervated by the obturator nerve. The video highlights the adductor longus's importance in activities like crossing legs and balancing the pelvis during movement. Kenhub offers an engaging alternative to traditional textbooks, promoting interactive learning through videos, quizzes, and an anatomy atlas.

Takeaways

• 😀 The adductor longus is part of the inner hip musculature, playing a crucial role in hip movement.
• 😀 It originates from the superior pubic ramus and pubic symphysis, inserting at the linea aspera of the femur.
• 😀 Distally, the adductor longus forms an aponeurosis that extends to the vastus medialis muscle.
• 😀 The muscle is primarily innervated by the obturator nerve, which travels through the obturator canal.
• 😀 The femoral artery and vein, along with the saphenous nerve, run within the adductor canal, located between key thigh muscles.
• 😀 The main function of the hip adductors is to facilitate the adduction of the hip joint.
• 😀 The adductor longus also supports hip flexion and is actively engaged when crossing legs.
• 😀 These muscles play an essential role in balancing the pelvis during activities like standing and walking.
• 😀 The tutorial promotes Kenhub as an engaging alternative to traditional textbooks for learning anatomy.
• 😀 Viewers are encouraged to explore more resources such as videos, quizzes, and an anatomy atlas on the Kenhub platform.

Q & A

What is the primary focus of this tutorial?

The tutorial focuses on the anatomy and function of the adductor longus muscle.

Where are the hip adductors located?

The hip adductors are part of the inner hip musculature, extending from the lower pelvic bone to the femur and knee region.

How does the adductor longus muscle contribute to the thigh?

The adductor longus shapes the surface anatomy of the medial thigh and plays a role in the adduction of the hip joint.

What is the origin and insertion of the adductor longus?

The adductor longus originates at the superior pubic ramus and pubic symphysis, and it inserts at the linea aspera.

What is the function of the vastoadductorial membrane?

The vastoadductorial membrane is an aponeurosis formed distally by the adductor longus that extends to the vastus medialis muscle.

Which nerve innervates the adductor longus muscle?

The obturator nerve, which arises from the lumbar plexus, innervates the adductor longus muscle.

What is the significance of the adductor canal (Hunter’s canal)?

The adductor canal is a space that contains the femoral artery and vein, as well as the saphenous nerve, located between the adductor magnus, adductor longus, and vastus medialis muscles.

What is the primary function of the hip adductors?

The main function of the hip adductors is to facilitate the adduction of the hip joint.

How do hip adductors assist in everyday movements?

Hip adductors, including the adductor longus, are particularly engaged when crossing one’s legs and help in balancing the pelvis during standing and walking.

What resources does Kenhub offer for learning anatomy?

Kenhub offers videos, interactive quizzes, articles, and an atlas of human anatomy to enhance the learning experience.
