The humerus doesnt flex. bones dont flex. but the muscles on top are called biceps.
Latissimus dorsi
a bone
gastrocin
The subscapularis muscle originates on the anterior surface of the scapula and inserts on the proximal anterior humerus. Its function is to rotate the head of the humerus medially.
flexes the big toe
deltoid
The gastrocnemius (plantar flexes the foot) is the muscle which is opposite of the tibialis anterior dorsiflexor of the foot).
The biceps brachii muscle.
This muscle flexes and adducts the humerus. It is also a synergist of the pectoralis major
The gastronemius muscle is one of the calf muscles and it plantar flexes the foot or flexes the knee.
The structure connecting the pectoral muscle to the humerus is
The humerus is one of the bones in your arm.
gastrocin
it flexes and rotates the head
sternocleidomastoid
quadricep
i THE ILIOPSOAS
Abductor muscle - moves a limb away from the midlineAdductor muscle - moves a limb towards the midlineExtensor muscle - increase the angle at a joint - extends a limbFlexor muscle - decreases the angle at a joint - flexes a limbPronator muscle - turns a limb to face downwardsSupinator muscle - turns a limb to face upwardsRotator muscle - rotates a limbIn the human body, these are the responsible muscles.*Muscles which move the thigh and their action*Gluteus maximus - Extends and rotates thigh laterally.Adductor longus - Adducts, medially rotates and flexes the thighAdductor brevis - Adducts, laterally rotates and flexes the thighAdductor magnus - Adducts, flexes, laterally rotates and extends the thigh.Rectus femoris - Extends knee and flexes hipVastus lateralis - Extends kneeVastus medialis - Extends kneeVastus intermedius - Extends kneeSartorius - Flexes knee. Flexes hip and rotates femur laterallyBiceps femoris - Flexes leg and extends thighSemitendinosus - Flexes leg and extends thighSemimembranosus - Flexes leg and extends thigh
