flexor

Joint-closing muscle type

A flexor is a muscle that bends a joint, drawing two body parts closer together—the opposite of an extensor.

The biceps is a flexor that bends the elbow; the hamstrings are flexors that bend the knee.

The term appears mainly in anatomy and medicine: flexor tendon, flexor injury.
