Meet FLEXOR DIGITORUM PROFUNDUS! Our second last Wrist Flexor muscle:
This
muscle spreads over a large portion of your ULNA bone (one of two
forearm bones - the one on the pinky side!) > and then just above the
wrist it SPLITS into FOUR tendons > which then extend to the tips of
all your fingers (except the thumb)
Official Attachment Points:
Origin: Anterior & medial surfaces of the proximal 3/4 of the ulna.
Insertion: by 4 tendons into the bases of the distal phalanges of fingers 2-5.
The four tendons pass through the carpal tunnel of the
wrist! (If you're reading this you're probably on the computer right
now! And FLEXOR DIGITORUM PROFUNDUS is busy at at work helping you to
scroll and type your heart out!
MUSCLE ACTIONS!
1. Assists in WRIST FLEXION
2. FLEXES the 2nd - 5th fingers
Most of our 'activities of daily living' involve FLEXION of the fingers/hands/wrist.
This encourages a curled up position of the hand and a
tightening in the wrist & forearm that can result in tingly or numb
fingers.
This tightness can travel up the
arm to the shoulder as of course everything is connected ! If this
numbness/tingly finger feeling rings true for you (or a loved one!) come
on down to Sage wellness where we can 'clean things up' and explore the
issue further! In the meantime - play with gently bending each finger
back - giving each individual a nice stretch!
