Anatomy Q3
Arteries of the Appendicular Region
| Term | Definition |
|---|---|
| R & L Common Iliac arteries | terminal branches of the aorta; branch into the external & internal iliac arteries |
| AG - Common Iliac* | runs along the superior medial border of the psoas major muscle toward the lower extremity |
| AG - External Iliac | along the inferior medial border of the psoas major muscle |
| AL - External Iliac | it passes obliquely, inferiorly & laterally along the border of the psoas major muscle from the bifurcation of the common iliac to a point beneath the inguinal ligament |
| What artery does the external iliac become? | femoral |
| AG - Femoral Artery* | located through the center of Scarpa's triangle bound laterally by the sartorius muscle & medially by the adductor longus muscle |
| AL - Femoral Artery | begins at a point behind the inguinal ligament and ends at the opening of the adductor magnus muscle |
| LG - Femoral Artery | a line drawn on the surface of the thigh from the center of the inguinal ligament to a point on the medial condyle of the femur |
| AG - Popliteal Artery | a continuation of the femoral artery and is located at the back of the knees; descends from the opening of the adductor magnus muscle to the lower border of the popliteus muscle, passing behind the knee joint; divides into the P & A Tibial arteries |
| AL - Popliteal Artery* | begins at the opening of the adductor magnus muscle & terminates at the inferior border of the popliteus muscle |
| LG - Popliteal Artery | a line drawn through the center of the popliteal space parallel to the long axis of the lower extremity |
| Ag - Anterior Tibial Artery | inferior & lateral edge of the tibia; originates at the bifurcation of the popliteal artery at the lower border of the popliteal space; becomes the dorsalis pedis |
| AL - Anterior Tibial Artery | beings at the inferior border of the patella to the anterior surface of the ankle joint |
| LG - Anterior Tibial Artery* | a line drawn from the lateral border of the patella to the anterior surface of the ankle joint |
| AG - Dorsalis Pedis Artery* | a continuation of the anterior tibial artery & lies between or in the groove between the tendon of the extensor hallucis longus muscle & the tendon of the extensor digitorum muscle on the dorsal surface of the foot |
| LG - Dorsalis Pedis Artery | a line drawn from the center of the anterior surface of the ankle joint to a point midway between the big toe & 2nd toe |
| Arcuate Artery | top of the foot (tongue of the shoe) |
| AL - Posterior Tibial Artery | begins at the inferior border of the popliteal space and ends at the origin of the abductor hallucis muscle |
| LG - Posterior Tibial Artery* | a line drawn from the center of the popliteal space to a point midway between the medial malleolus & the calcaneus bone |
| AG - Posterior Tibial Artery | the groove behind & below the medial/inner malleolus; begins at the lower border of the popliteal space opposite the interval between the tibia and fibula |
| AL - Right Subclavian Artery | begins at a point behind the sternoclavicular articulation and extends to the lateral border of the 1st rib |
| A: - Left Subclavian Artery | begins at the level of the 2nd costal cartilage and extends to the lateral border of the 1st rib |
| Vertebral Arteries | 1. paired - left & right 2. supply the posterior regions of the brain 3. pass through the foramen magnum & join to become the basilar artery |
| Basilar Artery | an unpaired artery that ascends along the ventral midline of the brain to connect with the Circle of Willis; formed by the joining of the vertebral arteries |
| AG - Axillary Artery* | along or just behind the medial border of the coracobrachialis muscle |
| AL - Axillary Artery | begins at the lateral border of the 1st rib & extends to the lower border of the tendon of the teres major muscle |
| LG - Axillary Artery | a line drawn through the center of the base of the axillary space & parallel to the long axis of the upper extremity when abducted |
| AG - Brachial Artery | lies posterior to the medial border of the belly of the biceps brachii muscle |
| AL - Brachial Artery | begins at the lower border of the tendon of the teres major muscle & extends just inferior to the antecubital fossa |
| LG - Brachial Artery | a line drawn from the center of the base of the axillary space to the center inner bend of the antecubital fossa |
| AG - Radial Artery | located just lateral to the tendon of the flexor carpi radialis muscle |
| AL - Radial Artery | from a point just inferior to the antecubital fossa to the palm of the hand |
| LG - Radial Artery | a line drawn from the center of the antecubital fossa to the center of the base of the index finger |
| Radial Artery | becomes the Deep Palmar Arch, which then branches into the Digital Arteries |
| AG - Ulnar Artery* | lies lateral to the tendon of the flexor carpi ulnaris muscle, between the tendons of the flexor carpi ulnaris & the flexor carpi digitorum superficialis |
| AL - Ulnar Artery* | extends from the antecubital fossa to the palm of the hand |
| LG - Ulnar Artery* | a line drawn from the center of the antecubital fossa to a point between the 4th & 5th fingers |
| Ulnar Artery | becomes the Superficial Palmar Arch which branches into the Digital Arteries |
