Anatomy & Components of the Femoral Triangle (~8:13 @ top - INFERIOR Epi. A.)

The video tutorial provides an in-depth exploration of the femoral triangle, a key anatomical region in the lower extremities. It begins with an introduction to the lower extremities and the femoral triangle, followed by a detailed explanation of its boundaries, including the inguinal ligament, sartorius muscle, and adductor longus. The tutorial then discusses the contents of the femoral triangle, such as the lateral femoral cutaneous nerve, femoral nerve, artery, and vein. It also covers the femoral sheath and the arterial supply, including the common femoral artery and its branches. Finally, the video explains the venous drainage system, highlighting the great saphenous vein and the profunda femoris vein.

What is the femoral triangle primarily used for in anatomical studies?

• To study the anatomy of the upper extremities

• To understand the placement of structures beneath the inguinal ligament

• To identify the location of the heart

• To examine the structure of the skull

Which muscle forms the lateral boundary of the femoral triangle?

• Pectineus

• Sartorius

• Adductor longus

• Iliopsoas

What is the role of the lateral femoral cutaneous nerve?

• To drain lymph from the thigh

• To supply blood to the thigh

• To supply sensory input to the superficial structures of the thigh

• To supply motor input to the thigh

Which structures are contained within the femoral sheath?

• Femoral nerve and artery

• Common femoral artery, common femoral vein, and lymphatic vessels

• Sartorius and adductor longus muscles

• Lateral femoral cutaneous nerve and genitofemoral nerve

What is the source of the common femoral artery?

• Superior epigastric artery

• Common iliac artery

• Internal iliac artery

• External iliac artery

Which artery is known as the deep artery of the thigh?

• Common femoral artery

• Lateral femoral circumflex artery

• Superficial femoral artery

• Profunda femoris artery

What is the primary function of the superficial femoral artery?

• To supply blood to the abdominal wall

• To supply blood to the knee and lower leg

• To supply blood to the head and neck of the femur

• To supply blood to the thigh

Which vein is responsible for returning blood from the lower leg to the common femoral vein?

• Medial femoral circumflex vein

• Lateral femoral circumflex vein

• Great saphenous vein

• Profunda femoris vein

Where does the great saphenous vein dump its blood?

• Into the profunda femoris vein

• Into the popliteal vein

• Into the common femoral vein

• Into the external iliac vein

What happens to the common femoral vein as it crosses the inguinal ligament?

• It becomes the popliteal vein

• It becomes the external iliac vein

• It becomes the great saphenous vein

• It becomes the internal iliac vein
