| The ulnar nerve also innervates the adductor pollicis and first dorsal interosseous muscles, which allow pinch. |
|
| These arteries supply the interosseous muscles and bones and the second, third, and fourth lumbrical muscles. |
|
| It is innervated by the anterior interosseous nerve and may be represented as the tibialis posterior of the leg. |
|
| These vessels anastomose with the radial recurrent and the interosseous recurrent arteries, respectively. |
|
| It may join the radial artery at the wrist, or if the radial stops short of the carpus the posterior interosseous artery may replace it. |
|
| The sacroiliac ligament is a strong interosseous connection between the sacrum and ilium on the posterior surface. |
|
| It is attached to the cuboid by an interosseous ligament and to the cuboid and navicular bones by the strong bifurcate ligament. |
|
| The dorsal interosseous muscles are larger than their plantar counterparts, are four in number, and fill the intermetatarsal spaces. |
|
| Still more rarely, it gives rise to the interosseous artery or a vas aberrans. |
|
| The palmer interosseous muscles adduct the fingers toward the axial line or the middle digit, and the dorsal interosseous muscles are abductors of the fingers. |
|
| The anterior compartment is defined by the tibia, interosseous septum, fibula, and a line of fascia extending from it in an anterolateral direction. |
|
| It is innervated by the anterior interosseous branch of the median nerve. |
|
| The first dorsal interosseous muscle inserts into the extensor expansion. |
|
| In some cases, the arch is reinforced or completed by a large median artery, arising frequently from the common interosseous, or from an enlarged metacarpal artery. |
|
| Finally, the remaining ligament of the syndesmosis is the interosseous ligament. |
|
| Interosseous ligaments refer to ligaments connecting carpal bones, whereas extraosseous ligaments connect the ulna and radius to the carpal bones. |
