In anatomy, flexor is a muscle that contracts to perform flexion (from the Latin verb flectere, to bend),[1] a movement that decreases the angle between the bones converging at a joint. For example, one's elbow joint flexes when one brings their hand closer to the shoulder, thus decreasing the angle between the upper arm and the forearm.
Flexors
Upper limb
- of the humerus bone (the bone in the upper arm) at the shoulder
- of the forearm at the elbow
- of carpus (the carpal bones) at the wrist
- of the hand
Lower limb
Hip
The hip flexors are (in descending order of importance to the action of flexing the hip joint):[2]
- Collectively known as the iliopsoas or inner hip muscles:
- Anterior compartment of thigh
- Rectus femoris (part of the quadriceps muscle group)
- Sartorius
- One of the gluteal muscles:
- Medial compartment of thigh
Without the iliopsoas muscles, flexion in sitting position is not possible across the horizontal plane.[2]
