Official Attachment points!
ORIGIN(s): this muscle actually comes from two different spots close to the elbow:
a) common flexor tendon which attaches to the medial epicondyle of the humerus!
a) common flexor tendon which attaches to the medial epicondyle of the humerus!
b) 'posterior surface of proximal half of ulnar shaft' (back of the elbow then half-way down the forearm - along the ulna) !
INSERTION: the muscle tendon continues and attaches onto a small wrist bone called the Pisiform**
*the ulna is one of two forearm bones - its the one on the pinky side!
** the Pisiform is that bump on the pinky side of the wrist > just above the wrist crease - can you feel it?
a) FLEXES the hand a the WRIST joint (aka wrist flexion)
b) ADDUCTS the hand aka ADDuction (tipping hand Towards the midline of the body as opposed to Away which would be ABDuction.
c) - also assists in FOREARM FLEXION because this muscle crosses the elbow joint.
If you want to FEEL your own FLEXOR CARPI ULNARIS: look
at your hand - palm up > locate the wrist bone PISIFORM (that bump
on the pinky side of your wrist!) > slide your thumb OFF pisiform
moving up the arm (ulnar side) WHILST ADDUCTING the hand > It is the
act of Adduction that will contract and help you to feel FLEXOR CARPI
ULNARIS !!
