Compartments of leg vessels3/19/2023 ![]() The popliteal vein also travels with the artery in this space and is continuous with the femoral vein. When the femoral artery travels through the opening in the adductor magnus and emerges into this space, it is now called the popliteal artery. This region is called the popliteal fossa. Popliteal artery : Observe the diamond-shaped region at the posterior aspect of the knee, bounded superiorly by the hamstring tendons on each side and inferiorly by the lateral and medial heads of the gastrocnemius.In comparison, the inferior gluteal artery and nerve exit the greater sciatic foramen inferior to the piriformis muscle. The superior gluteal artery and nerve leave the greater sciatic foramen superior to the piriformis muscle. The ligaments of the pelvis for the greater sciatic foramen in the region of the greater sciatic notch of the pelvis and the inferior and superior gluteal arteries and nerves both travel through this foramen.The arteries are branches off of the internal iliac arteries. Together these nerves and vessels supply and innervate the muscles of the gluteal region and lateral thigh. The inferior gluteal nerve and artery travel together, while the superior gluteal nerve and artery travel together. Gluteal Region: Observe the inferior and superior gluteal nerves and inferior and superior gluteal arteries.Posterior Neurovasculature of the Lower Extremity You will view the anterior structures on two of the extremities and posterior structures on the other two extremities. The lower extremity tissue will be positioned with either the anterior side or posterior side up. By following a nerve or artery to a specific muscle, you can determine which artery or nerve it is. Like the previous units, you should use nearby structures as a reference when identifying neurovascular structures of the lower extremity. Lab Activity 1: Lower Extremity Cadaveric Tissue -Arteries and Nerves You should reference the muscle tables posted on Canvas to see the specific muscles innervated by each nerve. In future labs, we will study this more in-depth. ![]() In this lab, we will mention the general area innervated and supplied by these nerves and vessels. Over the next two labs, you will learn about the muscles, and you will make the connection between these nerves and vessels and the muscles they innervate or supply. By the end of the lab today, you should have identified all of the structures on the list using multiple modalities. Keep in mind that all structures are not visible on all tissue or other tools, and that is okay. You will explore the nerves, arteries, and veins of the gluteal region, thigh, leg, and foot. Today you will learn about the neurovasculature of the lower extremity. Describe the veins of the lower extremity and identify the regions drained by each vein.Describe the arteries of the lower extremity and identify the regions supplied by each artery.Identify the muscles and sensory regions innervated by each nerve of the lower extremity.Explain the anatomy of the nerves of the lower extremity.
