The flexion (from Latin flectere ' to bend' , ' to bend', 'to twist') is the flexion of a joint . The opposite movement is called extension .
In the wrist , flexion (movement towards the palm ) is usually referred to as palmar flexion , and in the ankle joint (movement towards the sole of the foot) as plantar flexion . The term inclination or ventral flexion is usually used for the spine .
Excessive flexion is called hyperflexion .
A skeletal muscle that flexes a joint is called a flexor or flexor . In some anatomical muscle names, especially muscles of the forearm and lower leg , the term occurs explicitly as a second part of the name , e.g. B. Flexor hallucis longus muscle ('long flexor of the big toe').
