Summary
Highlights
The deep femoral vein and its branches (medial and lateral circumflex femoral veins) are discussed. The great saphenous vein and small saphenous vein, significant superficial veins, are also presented, noting the great saphenous vein's use in coronary artery bypass grafts.
The video introduces the focus on arteries and veins of the upper and lower limbs, using a wire man model for anatomical orientation. It starts with the subclavian artery, followed by the axillary artery and its various branches like the thoracoacromial, lateral thoracic, superior thoracic, subscapular, and circumflex scapular arteries.
Continuing from the axillary artery, the video moves to the brachial artery, highlighting its branches including the anterior and posterior circumflex humeral arteries, deep brachial artery, and superior and inferior ulnar collateral arteries.
The brachial artery then splits into the radial and ulnar arteries. Key branches discussed are the common interosseous artery (splitting into anterior and posterior interosseous), ulnar recurrent artery, and radial recurrent artery. The video then details the superficial palmar arch, common palmar digital arteries, proper palmar digital arteries, deep palmar arch, dorsal carpal arch, dorsal metacarpal arteries, and dorsal digital arteries of the hand.
The tutorial shifts focus to the lower limb arteries, starting from the abdominal aorta's bifurcation into the common iliac arteries, which then divide into external and internal iliac arteries. The primary focus is on the external iliac artery.
The external iliac artery transitions into the femoral artery. Important branches covered are the deep femoral artery, lateral circumflex femoral artery, and medial circumflex femoral artery. Lesser branches like the descending genicular and various superior/inferior genicular arteries are also mentioned.
The femoral artery leads to the popliteal artery, which then branches into the anterior tibial artery, posterior tibial artery, and fibular (peroneal) artery. Recurrent tibial arteries are also identified.
Tracing the anterior tibial artery into the foot, the dorsalis pedis artery is shown, leading to the arcuate artery, dorsal metatarsal arteries, and dorsal digital arteries. This section emphasizes the dorsal aspect of the foot.
The video then explains the plantar aspect of the foot, originating from the posterior tibial artery, which divides into the medial and lateral plantar arteries. These form the plantar arch, giving rise to plantar metacarpal and plantar digital arteries. It's noted that this section is harder to visualize on the model.
The tutorial transitions to the veins of the upper limb, starting with the subclavian vein, its tributaries (external jugular, vertebral, internal jugular veins), and its continuation into the axillary vein. Key superficial veins are the cephalic vein (thumb side) and the basilic vein (pinky side).
The brachial vein is introduced as a deeper vein. The median cubital vein, which connects the cephalic and basilic veins in the antecubital region, is highlighted. The median antebrachial vein, radial vein, and ulnar vein are also identified. The palmar venous arch and dorsal venous arch (connecting cephalic and basilic veins on the dorsum of the hand) are explained, along with dorsal metacarpal and dorsal digital veins.
The video then covers the lower limb veins, beginning with the inferior vena cava, which bifurcates into common iliac veins, then external and internal iliac veins. The external iliac vein leads to the femoral vein.
The femoral vein receives blood from the popliteal vein, which is fed by the anterior tibial vein, fibular (peroneal) vein, and posterior tibial vein. In the foot, the dorsalis pedis vein is shown, supplied by the dorsal venous arch, which further receives blood from dorsal metatarsal and dorsal digital veins. The plantar veins (medial and lateral plantar veins forming the plantar venous arch) and their tributaries (plantar metatarsal and plantar digital veins) are mentioned as difficult to visualize but important.
