Superficial palmar arch – located anteriorly to the flexor tendons in the hand and deep to the palmar aponeurosis. It gives rise to the digital arteries, which supply the four fingers.
What gives rise to the occipital artery?
The occipital artery originates from the posterior surface of the external carotid artery, at the level of the angle of the mandible, and courses posteriorly and upward, being crossed superficially by the hypoglossal nerve.
Which blood vessel gives rise to the dorsalis pedis artery?
The anterior tibial artery is located between the tibia and fibula, and supplies blood to the muscles and integument of the anterior tibial region. Upon reaching the tarsal region, it becomes the dorsalis pedis artery, which branches repeatedly and provides blood to the tarsal and dorsal regions of the foot.
Which artery gives rise to the anterior and posterior tibial arteries?
The posterior tibial artery of the lower limb is an artery that carries blood to the posterior compartment of the leg and plantar surface of the foot. It branches from the popliteal artery via the tibial-fibular trunk.

Which artery gives rise to both the radial and ulnar arteries?
After giving rise to the radial collateral artery, the brachial artery will first give rise to the superior ulnar collateral and then to the inferior ulnar collateral. These arteries course posteriorly and anteriorly to the medial epicondyle of the humerus, respectively.
Is there a right and left occipital artery?
The occipital artery arises from the external carotid artery opposite the facial artery. Its path is below the posterior belly of digastric to the occipital region.

How does occipital neuralgia start?
Occipital neuralgia may occur spontaneously, or as the result of a pinched nerve root in the neck (from arthritis, for example), or because of prior injury or surgery to the scalp or skull. Sometimes “tight” muscles at the back of the head can entrap the nerves.
Which leg has the main artery?
The main artery of the lower limb is the femoral artery. It is a continuation of the external iliac artery (terminal branch of the abdominal aorta). The external iliac becomes the femoral artery when it crosses under the inguinal ligament and enters the femoral triangle.
Is there a dorsalis pedis vein?
In human anatomy, the dorsalis pedis artery (dorsal artery of foot), is a blood vessel of the lower limb that carries oxygenated blood to the dorsal surface of the foot. It is located 1/3 from medial malleolus. … Along its course, it is accompanied by a deep vein, the dorsalis pedis vein.
Where are your main arteries located?
The largest artery is the aorta, the main high-pressure pipeline connected to the heart’s left ventricle. The aorta branches into a network of smaller arteries that extend throughout the body. The arteries’ smaller branches are called arterioles and capillaries.
What are the signs of clogged arteries in your legs?
“But claudication is an indication that narrowed arteries may be reducing blood flow to the legs.” Other signs of poor blood flow in the lower limbs include loss of leg hair and foot ulcers that don’t heal. Tell your doctor if you have fatigue or cramping in the calf, thigh or hip when walking.
What muscles does the posterior tibial artery supply?
The posterior tibial artery passes posterior to the popliteus muscle and pierces the soleus muscle. The posterior tibial artery then descends between the tibialis posterior and flexor digitorum longus muscles. The posterior tibial artery supplies blood to the posterior crural compartment.
Which is bigger ulnar or radial artery?
Results: The mean diameter of the radial artery was 28% larger than that of the ulnar artery in the right arm (p < 0.001) and 26% larger in the left arm (p < 0.001).
How deep down is the radial artery?
The anterior wall of the typical radial artery is 3 mm under the skin, so a lot of depth is not necessary.
What happens if you cut the ulnar artery?
Although it has been noted that the final results of these injuries are mainly dependent on the associated injuries, loss of ulnar or radial perfusion to the hand can lead to cold sensitivity, muscle and bone atrophy, and loss of strength.
