Flexion and extension

Some movements of synovial joints are flexion and extension. Flexion decreases a joint angle; for example - bending of the elbow. Extension is a movement that straightens the joint. It normally will return the body part back to zero position. For example, straightening the elbow can be an example of extension. Hyperextension is extending a joint beyond the zero position.

This image shows some examples of the movements of joints and their terminology. Flexion and extension refer to the bending and stretching of joint while hyperextension refers to the stretching of a joint past anatomical position. Dorsiflexion and plantar flexion refers to the flexing and pointing of the foot, respectively. Adduction and abduction refers to the movement towards and away from the midline of the body, respectively.

Special movements of the foot can be classified as dorsiflexion, plantar flexion, inversion, and eversion. Dorsiflexion is a movement in which the toes are elevated. Plantar flexion is pointing the toes downward; it can be compared to pressing a gas pedal. Inversion is the medial movement of the soles and eversion is moving the soles laterally.
