MEDICAL PHYSIOLOGY

Detailed explanation-1: -Flexion: Moving the base of the finger towards the palm. Extension: Moving the base of the fingers away from the palm. Adduction: Moving the fingers toward the middle finger. Abduction: Moving the fingers away from the middle finger.

Detailed explanation-2: -Flexion is the strongest movement that the fingers perform and is used during grasp and pinch. Each finger has two muscles involved in flexion; flexor digitorum profundus, which attaches to the distal phalanx, and flexor digitorum superficialis, which attaches to the middle phalanx.

Detailed explanation-3: -The middle joint of the finger is called the proximal interphalangeal joint, or PIP for short. This joint can bend into flexion more than any other joint in the finger-more than 90 degrees in most people. The PIP joint, however, has almost no ability to move into extension.

Detailed explanation-4: -Dupuytren’s contracture is when 1 or more fingers bend in towards your palm. There’s no cure, but your fingers can be straightened if it’s severe.

Detailed explanation-5: -Patients use many terms for finger flexion: bending. making a fist. gripping.
