Adductor longus, Adductor brevis, Adductor magnus, Gracilis, Obturator externus

Medial thigh muscles

Obturator nerve

The Medial thigh muscles are generally innervated by ___

Adductor longus

Most anterior muscle in the adductor group

Adductor longus

Fan-shaped muscle

Adductor longus

Forms the medial border of the femoral triangle

Adductor longus

From the body of pubis, inferior to pubic crest

Adductor longus

Inserted to Middle third of linea aspera of femur

Obturator nerve

Innervation of Adductor longus

Adductor longus

Adducts thigh

Adductor brevis

Shortest muscle in the adductor group

Adductor brevis

The anterior and posterior divisions of the obturator nerve pass anterior and posterior to this muscle

Adductor brevis, Gracilis

From body and inferior ramus of pubis

Adductor brevis

From to Pectineal line inserted to proximal part of linea aspera of femur

Obturator nerve

Innervation of Adductor brevis

Adductor longus, Adductor brevis

Innervated by Anterior Obturator nerve

Adductor magnus

Largest, most powerful muscle in the adductor group

Adductor magnus

Comprised of an adduction portion and a hamstring portion

Adductor magnus

Has an adductor hiatus, seen distally for the passage of neurovascular structures as it descends from the anterior to posterior part of the knee

Adductor magnus

Adductor portion is innervated by the obturator nerve

Adductor magnus

Hamstring is innervated by the tibial division of the sciatic nerve

Adductor of Adductor magnus

From inferior ramus of pubis and ramus of ischium

Hamstring of Adductor magnus, Semimembranosus, Semitendinosus

From ischial tuberosity

Adductor of Adductor magnus

Inserted to Gluteal tuberosity, Linea aspera, and Medial supracondylar line

Hamstring of Adductor magnus

Inserted to Adductor tubercle of femur

Obturator nerve

Innervation of Adductor of Adductor magnus

Sciatic nerve

Innervation of Hamstring of Adductor magnus

Adductor magnus

Adducts thigh by the adductor part flexing thigh and the Hamstring part extending thigh

Adductor hiatus

An opening or aperture at the distal part of adductor magnus

Adductor hiatus

Found between the insertion of the adductor part and insertion of the hamstring part of the adductor magnus

Adductor hiatus

Located just lateral and superior to the adductor tubercle of the femur

Adductor hiatus

Functions as a passage of neurovascular structures

Adductor hiatus

Transmites femoral artery and femoral vein from adductor canal (anterior part of the thigh) to the popliteal fossa (posterior to the knee)

Gracilis

Most medial, superficial, and weakest muscle in the adductor group

Gracilis

The only adductor to cross both the hip and the knee

Pes anserinus

The Gracialis, Sartorius, and Semitendinous have a common insertion on the tibia:___

Pubis

Origin of Gracilis

Gracilis

Inserted to superior part of medial surface of tibia

Gracilis

Adducts thigh, flexes leg, helps rotate leg medially

Semitendinosus, Sartorius, Gracilis

Muscles inserting on Pes anserinus

Obturator externus

Flat, Fan-shaped, deep muscle

Obturator externus

For external rotation of the hip

Obturator externus

Can act as both adductor and abductor of flexed hip

Obturator externus

From Margins of obturator foramen and obturator membrane

Obturator externus

Inserted to Trochantic fossa of femur

Obturator externus

Laterally rotates thigh, Steadies head of femur in acetabulum
