7 Σεπ 2024 · Flexion refers to a movement that decreases the angle between two body parts. Flexion at the elbow is decreasing the angle between the ulna and the humerus. When the knee flexes, the ankle moves closer to the buttock, and the angle between the femur and tibia gets smaller.
For the vertebral column, flexion (anterior flexion) is an anterior (forward) bending of the neck or body, while extension involves a posterior-directed motion, such as straightening from a flexed position or bending backward.
20 Ιουλ 2023 · Flexion, or bending, involves decreasing the angle between the two entities taking part in the movement (bones or body parts). In contrast, extension , or straightening, involves increasing the respective angle.
Flexion describes a bending movement that decreases the angle between a segment and its proximal segment. Extension is the opposite of flexion, describing a straightening movement that increases the angle between body parts

24 Φεβ 2023 · Dorsiflexion and plantar flexion are movements at the ankle joint, which is a hinge joint. Lifting the front of the foot, so that the top of the foot moves toward the anterior leg is dorsiflexion, while lifting the heel of the foot from the ground or pointing the toes downward is plantar flexion.
30 Οκτ 2023 · The main action of the ankle joint is to allow dorsiflexion and plantar flexion of the foot, as well as some degree of pronation and supination with subtalar and midtarsal joints. The joint also acts as a shock absorber as the heel strikes the ground during the first phases of gait.
