Gracilis: 1 of 5 Leg Adductor Muscles

We're back with another leg Adductor Muscle also known as one of your groin muscles: Gracilis!
The other Adductor Muscles are: Adductor Longus, Adductor Brevis, Adductor Magnus, & Pectinius!

Muscle Attachments

Origin: Anterior body and the inferior ramus of pubis 
Insertion: Pes Anserine Tendon (insertion) *

Muscle Action(s) :

Adduction of the thigh @ the hip joint
Flexion of the thigh @ the hip joint
Medial Rotation of the thigh @ the hip joint
Flexion of the leg @ the knee joint

the above image shows hip AND knee flexion.

*pes anserine insertion in an area just below knee - onto the tibia (lower leg bone)

Three muscles attach to the Pes Anserine Tendon : Gracilis, Sartorius, & SemiTendonosis 
(one of the hamstrings - yet to be covered!)

Pes Anserine actually roots back to the word "goose foot" because of three-pronged display of these 3 muscle tendons inserting!
