Neurovasculature of the Posterior Compartment of the Forearm

00:01 So, the arteries and nerves within this space, we've spoken about these at length in terms of the radial nerve contributing to this.

00:08 And here, we can see the radial nerve that gives rise to as number of branches as it runs distally.

00:13 We've got the superficial branch of the radial nerve that runs towards the hand but we've also got this deep branch and that gives rise to the posterior interosseous nerve which we've seen supplying a lot of the muscles within this region.

00:27 We've got the posterior interosseous artery that's also appearing from this region.

00:31 And we've got the anterior interosseous artery as well.

00:34 And these are emerging from the anterior compartment of the forearm, passing through apertures within the interosseous membrane to help supply this posterior compartment.

00:45 I appreciate that's been a whirlwind tour of muscles within the forearm.

00:50 There are a lot of muscles. The attachments, their origins, their insertions are all very detailed and again, please refer to your own learning objectives and curricular to know what you know need to know about these muscles.

01:03 Break the video down into the anterior and posterior compartments and even maybe the superficial, middle, and deep layers where they exist.

01:11 Consolidate your understanding. Good luck.
