This type of muscle contracts to bend a limb at a joint
a muscle that extends or straighten a limb or body part is called extensor
Two joint muscles in the upper limb is the wrist and the elbow. Two joint muscles in the lower limb is the ankle and the knee.
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

A muscle that straightens a joint is called an extensor.Extensors are the muscles whose contraction extends or straightens a limb or other part of the body.Extensor muscle
Flexor
Flexion is the medical term meaning bent at the joint. The opposite is extension.
Muscles move body parts by contracting and then relaxing. Your muscles can pull bones, but they can't push them back to their original position. So they work in pairs of flexors and extensors. The flexor contracts to bend a limb at a joint.

Triceps does not help to bend your arm. It helps to straighten your upper limb across the elbow.
