ANATOMY

Detailed explanation-1: -Flexion – bending a joint. This occurs when the angle of a joint decreases. For example, the elbow flexes when performing a biceps curl. The knee flexes in preparation for kicking a ball. Extension – straightening a joint.

Detailed explanation-2: -Flexion is the medical term for bending an arm or leg. Techically speaking, it’s a physical position that decreases the angle between the bones of the limb at a joint. It occurs when muscles contract and move your bones and joints into a bent position.

Detailed explanation-3: -Flexion – bending. This occurs when the angle between the articulating bones is decreased. For example, by bending the knee and bringing the heel of the foot to the bottom. The angle between the tibia and the femur (at the back of the knee) has decreased, therefore, flexion has taken place at the knee joint.

Detailed explanation-4: -In the limbs, flexion decreases the angle between the bones (bending of the joint), while extension increases the angle and straightens the joint.

Detailed explanation-5: -Hinge joints, such as at the knee and elbow, allow only for flexion and extension. Similarly, the hinge joint of the ankle only allows for dorsiflexion and plantar flexion of the foot.
