    In this lecture, we are going to look at the superficial structures and cutaneous innervations of the upper limb. So we are going to look at the fascia of the upper limb. This connective tissue layer. We'll look at the superficial and deep fascia. We'll then look specifically at an example we'll look at the brachial fascia. We'll then look at the venous drainage. We will look at the cephalic vein, the basilic vein and how they run into the axillary vein and we will also look at the communication between the two known as the median cubital vein. We'll then look at the cutaneous innervation of the upper limb. We'll look at the dermatomal distribution and then we'll move on to some specific cutaneous nerves. So here we can see we have got both an anterior and a posterior view of the upper limb. And we can see that covering all of these muscles which we are go in to detail, is a white glistening layer and this is the deep fascia. We have deep fascia and we call it deep fascia. Because we also have superficial fascia and the superficial fascia which we can't see on these pictures because that lies deep to the skin and the skin has been removed. The deep fascia is what we can see surrounding the muscles, on the superficial fascia is this loose connective tissue and fatty layer. So we can't see that because it has been removed. But it is made up of loose connective tissues and varying amounts of fats. The superficial fascia lies deep to the skin and it is therefore pierced by cutaneous nerves that supply the skin and also superficial veins. Lying between the superficial fascia and the skeletal muscle, biceps brachii for example we have the...

    Precise enunciation, simplified explanations, attention grabbing
    By Steven S. on 24. March 2017 for Cutaneous Innervation and Venous Drainage of Upper Limb

    Doctor James offers precise simplified explanations which are easy to understand and it is easy to remain concentrated throughout the lecture. I liked the way he helped me draw a mental picture of the venous system of the upper limb from the hand to the heart. I would recommend this video to people who are considering taking the USMLE step 1

    very good lecture
