Passing backward to the upper border of the interosseous membrane, it divides into two branches, the posterior interosseous arteries.

By exercising individual fingers and thumb in adduction and abduction motion in pronation position, interosseous ] muscles will gain strength.
24.
It serves for the attachment of the interosseous membrane, which separates the extensor muscles in front from the flexor muscles behind.
25.
Where it lies upon the abductor pollicis longus and the extensor pollicis brevis, it is accompanied by the dorsal interosseous nerve.
26.
This has classically been attributed to arterial disruption, but may also occur after events that produce venous congestion with elevated interosseous pressure.
27.
As opposed to carpal tunnel syndrome, the AIN has no sensory fibers and therefore no numbness associated with the Anterior Interosseous Syndrome.
28.
It is continuous below with the interosseous ligament of the tibiofibular syndesmosis, and presents numerous perforations for the passage of small vessels.
29.
At the lower part of the forearm it anastomoses with the termination of the volar interosseous artery, and with the dorsal carpal network.
30.
The first dorsal metacarpal artery arises directly from the radial artery before it crosses through the two heads of the first dorsal interosseous muscle.
