What is the action of the adductors?

What is the action of the adductors?

Originating at the pubis and the ischium (lower portions of the pelvis—the hipbone), these ribbonlike muscles are attached along the femur (thighbone). Their primary action is adduction of the thigh, as in squeezing the thighs together; they also aid in rotation and flexion of the thigh.

What is the joint action of the adductor magnus?

Adductor magnus muscle
Insertion Linea aspera and adductor tubercle of femur
Artery Deep femoral artery
Nerve Posterior branch of obturator nerve (adductor) and sciatic nerve (hamstring)
Actions Adduction of hip (both portions) flexion of hip (adductor portion) extension of hip (hamstring portion)

What is the main action of the adductor brevis?

The adductor brevis is a muscle in the thigh situated immediately deep to the pectineus and adductor longus. It belongs to the adductor muscle group. The main function of the adductor brevis is to pull the thigh medially.

What causes tight adductors?

Osteitis Pubis develops when poor biomechanics, the patterns and way you move your body, overload and overburden your adductors. Your overworked adductors become fatigued and dysfunctional. They stiffen, develop trigger points and eventually develop OP.

Which is the primary action of the adductor muscles?

Additionally, adductor brevis assists in flexion and medial rotation of the femur at the hip joint. Primarily, the action of adductor longus is adduction of the thigh at the hip joint. It also assists in flexion and medial rotation of the femur at the hip joint. The primary action of gracilis is adduction of the thigh.

Where is the adductor longus muscle located in the hip?

Adductor longus muscle. It inserts at the medial lip of the linea aspera that belongs to the middle one-third of the femoral shaft. Distally it forms an aponeurosis extending to the vastus medialis muscle (vastoadductorial membrane).

What are the muscles responsible for hip abduction?

Hip abduction is another movement where an altered movement pattern can develop in the hip. The gluteus medius muscle is the primary muscle responsible for hip abduction. The synergist muscles are the psoas, piriformis, TLF, quadratus lumborum and rectus femoris. The hip adductor muscles are the antagonists to the glutues medius.

Where does the adductor longus nerve supply sensation?

The nerve also supplies sensation to the upper medial thigh. The anterior branch runs in front of obturator externus, and runs posterior to adductor longus (which it supplies) and pectineus (supplied by the femoral nerve ). As the nerve passes the hip, it also gives an articular branch to the joint.
