2023年10月30日 · Flexion ( or palmar flexion) at the radioulnar joint is described as the movement in which the palmar aspect of the hand moves towards the forearm in the sagittal plane. During flexion, the scaphoid and lunate bones glide over the concave articular surface of the distal radius in a posterosuperior direction.

The interphalangeal joints of the hand are the hinge joints between the phalanges of the fingers that provide flexion towards the palm of the hand. There are two sets in each finger (except in the thumb, which has only one joint):

2016年8月10日 · Movement at both the radiocarpal and midcarpal joints is necessary to achieve the full range of motion (ROM) of the wrist, which has been classified as a condyloid joint with 2 degrees of freedom. 3 Motions present at the wrist include flexion, extension, abduction (radial deviation), and adduction (ulnar deviation).

2023年11月3日 · Palmaris longus is the most superficial muscle of the superficial forearm flexors, found deep to the forearm skin. It sits between the flexor carpi radialis and flexor carpi ulnaris muscles, superficial to the flexor digitorum superficialis muscle.

The wrist includes three joints: the distal radioulnar joint, the radiocarpal joint and the midcarpal joint. The movements at the wrist are flexion and extension, radial and ulnar deviation and pronation and supination (at the distal radioulnar joint). Optimal wrist function requires adequate range of motion.

2001年11月27日 · MP flexion occurs when activity in the FDS or FDP flexes the MP joint. The extensor mechanism is not 'stretchy.' When the digits flex (at the MP, PIP, or DIP joints), passive tension in the lateral bands and central slip pull the hood distally.

2017年8月1日 · Flexion: bending the wrist towards the palm. Muscles include: Flexor Carpi Ulnaris (prime mover), Flexor Carpi Radialis (prime mover), Palmaris longus (tightens the skin and fascia in the palm), Flexor Digitorum Superficialis (finger flexor, assists only).

2023年8月14日 · The motions of the flex carpal radialis muscle and the flexor carpal ulnaris muscle will equilibrate and manifest as palmar flexion. The action created by the flexor pollicis longus muscle is entirely on the thumb.

2024年12月31日 · The wrist, thenar, palmar, and digital flexion creases are skin flexion lines seen near synovial joints. These creases provide “folding points” in the skin, similar to the creases in a road map. Two creases are present over the proximal interphalangeal (PIP) joints, which account for the increased angles of flexion at these joints. By
