Why does my palmar interossei hurt?
Palmar interossei are the skeletal muscles of the hand that are responsible for movement of the fingers. Injury to the palmar interossei most frequently occurs due to overuse, such as typing for many hours. Inflammation of the muscles occur, making it difficult or painful to shake hands, type, or wiggle the fingers.
What is the dorsal hand?

What is interosseous muscle?
The interossei muscles are intrinsic muscles of the hand located between the metacarpals. They consist of four (or three) palmar and four dorsal muscles that, respectively. These muscles are responsible for finger adduction and abduction.
Why do we not need a 5th dorsal interossei?
The dorsal interossei muscles are muscles that abduct the second, third and fourth digits. The first digit and the fifth digit have their own abductor muscles in the thenar and hypothenar eminence and so do not have interossei musculature.
How do you strengthen palmar interossei?
Place your hand on a flat surface, with palms facing down. Slowly straighten the fingers as much as you can without straining your joints. Hold for a minute and then release. Repeat five times for each hand.
How many palmar interosseous muscles are there?
four
The palmar interossei are a group of paired intrinsic muscles of the hand located between the metacarpals. They consist of four, and sometimes three, palmar muscles that, adduct fingers. The palmar interossei also assist in flexion of the metacarpophalangeal joints and extension of the interphalangeal joints.
Can the middle finger adduct?
Gross anatomy They adduct the thumb, index, ring and little fingers along the long axis of the middle finger. Just like the dorsal interossei, the tendons pass deep to the transverse metacarpal ligament. There is no palmar interosseous muscle for the third digit as it cannot be adducted towards itself.
What is the function of the palmar interossei?
The palmar interossei are a group of paired intrinsic muscles of the hand located between the metacarpals. They consist of four, and sometimes three, palmar muscles that, adduct fingers. The palmar interossei also assist in flexion of the metacarpophalangeal joints and extension of the interphalangeal joints.
What is the palmar interossei?
The palmar interossei are three muscles located in the hand. They arise from the metacarpal bones of the index, ring and little finger and are innervated by the deep branch of the ulnar nerve. Together, those muscles work together to close your spread fingers.
What is the Order of the 3 palmar interosseous?
I – First Palmar Interosseous (to the index finger). II – Second Palmar Interosseous (to the ring finger). III – Third Palmar Interosseous (to the small finger). • Adducts fingers towards midline (which is the axis of the long finger metacarpal).
What are the músculos interósseos Palmares?
Os interósseos palmares são três músculos localizados no metacarpo. Eles surgem dos ossos do metacarpo dos dedos indicador, anelar e mínimo e são inervados pelo ramo profundo do nervo ulnar. Estes músculos trabalham em conjunto para fechar os dedos abertos.
What nerve innervates the palmar interossei?
Palmar interossei muscles. The palmar interossei are three muscles located in the hand. They arise from the metacarpal bones of the index, ring and little finger and are innervated by the deep branch of the ulnar nerve.
