Adductor Magnus - Podcast Version 0:00 / 0:00 1x 0.25x 0.5x 0.75x 1x 1.25x 1.5x 1.75x 2x The adductor magnus is a muscle of the medial compartment of the thigh. It is the largest muscle within this compartment and is comprised of two parts – an adductor component and a hamstring component. Attachments Adductor – Originates from the inferior rami of the pubis and the rami of ischium, attaches to the linea aspera of the femur. Hamstring part – Originates from the ischial tuberosity, attaches to the adductor tubercle and medial supracondylar line of the femur. Actions: Adductor – Adduction and flexion of the thigh Hamstring – Adduction and extension of the thigh. Innervation: Adductor – Obturator nerve (L2-L4) Hamstring part – Tibial component of the sciatic nerve (L4-S3). Blood Supply: Obturator artery, profunda femoris artery and medial circumflex femoral artery By TeachMeSeries Ltd (2026) Fig 1Muscles of the medial thigh.

The adductor brevis and obturator externus attach superiorly in the thigh, and so are not visible in this cross-section.

Learn More Frequent questions What is the adductor magnus muscle? The adductor magnus is the largest muscle in the medial compartment of the thigh, consisting of two distinct parts: an adductor component and a hamstring component. It plays a crucial role in thigh movements, including adduction and flexion. What are the attachments of the adductor magnus? The adductor part originates from the inferior rami of the pubis and the rami of the ischium, attaching to the linea aspera of the femur. The hamstring part arises from the ischial tuberosity and attaches to the adductor tubercle and medial supracondylar line of the femur. What actions does the adductor magnus perform? The adductor magnus facilitates adduction and flexion of the thigh through its adductor component, while its hamstring part is responsible for adduction and extension of the thigh. This dual functionality is important for various movements and stability. What is the innervation of the adductor magnus muscle? The adductor component is innervated by the obturator nerve (L2-L4), while the hamstring part receives innervation from the tibial component of the sciatic nerve (L4-S3). This specific innervation is essential for its motor functions. What is the blood supply for the adductor magnus? The adductor magnus is supplied by the obturator artery, profunda femoris artery, and medial circumflex femoral artery. This vascularisation is vital for delivering oxygen and nutrients to the muscle during activity. Rate This Article
