Thanks Synonym, not quite though !
I ended up looking at Gray's Anatomy to find the answer to my question.
The hypothenar group consists of the palmaris brevis, abductor digiti minimi, flexor digiti minimi, and opponens digiti minimi. They are all innervated by the ulnar nerve.
This group of muscles originates at the flexor retinaculum and carpal bones and inserts at the base of the proximal phalanx of the small finger.
What all this means in layman's language is this is the fleshy pad on the side of the hand opposite the thumb and between the wrist and the base of the little finger. An Alternative Site for blood testing as opposed to your fingers. (AST)
It is important to note that when your glucose is changing rapidly, there may be a difference in the glucose readings between your finger and other test sites, like the forearm, upper arm, thigh, calf, and other areas of the hand. Because blood flow to the finger is three to five times faster than other alternate sites, blood samples from the finger may show changes in your glucose sooner than the forearm, upper arm, thigh, calf, and other parts of the hand.
The possible difference in glucose readings between the finger and other alternate sites could delay your detection of hypoglycemia. Vigorous rubbing of the alternate test sites before lancing will help to minimize the difference between finger and other alternate site test results.
Before using Alternate Site Testing (AST) you should always discuss this with your HCP.
Clear as mud........ :wink:
