• Source: List of flexors of the human body

In anatomy, flexor is a muscle that contracts to perform flexion (from the Latin verb flectere, to bend), 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
Pectoralis major
Anterior deltoid
Coracobrachialis
Biceps brachii
of the forearm at the elbow
Brachialis
Brachioradialis
Biceps brachii
of carpus (the carpal bones) at the wrist
flexor carpi radialis
flexor carpi ulnaris
palmaris longus
of the hand
flexor pollicis longus muscle
flexor pollicis brevis muscle
flexor digitorum profundus muscle
flexor digitorum superficialis muscle

Hip


The hip flexors are (in descending order of importance to the action of flexing the hip joint):

Collectively known as the iliopsoas or inner hip muscles:
Psoas major
Iliacus muscle
Anterior compartment of thigh
Rectus femoris (part of the quadriceps muscle group)
Sartorius
One of the gluteal muscles:
Tensor fasciae latae
Medial compartment of thigh
Pectineus
Adductor longus
Adductor brevis
Gracilis
Without the iliopsoas muscles, flexion in sitting position is not possible across the horizontal plane.



Thigh

of thigh at knee (L5-S2)
Biceps femoris
Semitendinosus
Semimembranosus
Gracilis
Sartorius
Gastrocnemius
Popliteus
Plantaris (negligible)
of toes
Posterior compartment of leg
Flexor hallucis longus
Flexor digitorum longus
Flexor digitorum brevis
Quadratus plantae
Flexor hallucis brevis
Flexor digiti minimi brevis
of proximal phalanges at metatarsophalangeal joint
Lumbrical muscle (foot)
Plantar interossei
Dorsal interossei




= Other

=
torso/lumbar vertebrae
Rectus abdominis muscle
neck at atlanto-occipital joint
Longus capitis muscle
Longus colli muscle
