Anatomical Guide for the Popliteal Artery
Opening of adductor magnus to lower popliteus
A continuation of the femoral artery and is located at the back of the knees It descends from the opening of the adductor magnus muscle to the lower border of the popliteus muscle, passing behind the knee joint. Just below the knee joint it divides into the posterior and anterior tibial arteries.

Anatomical Guide for the Anterior Tibial Artery
Inferior and lateral edge of the tibia Originates at the bifurcation of the popliteal artery at the lower border of the popliteal space. At its point of termination, it becomes the dorsalis pedis artery.

Anatomical Guide for the Dorsalis Pedis Artery
Between extensor hallucis longus tendon & extensor digitorum tendon
Is a continuation of the anterior tibial artery and lies between or in the groove between the tendon of the extensor hallucis longus muscle and the tendon of the extensor digitorum muscle on the dorsal surface of the foot.
Linear Guide for the Dorsalis Pedis Artery
Anterior ankle joint - between 1st and 2nd toe
A line drawn from the center of the anterior surface of the ankle joint to a point midway between the big toe and adjacent toe (between 1st and 2nd toe).
Anatomical Limits for the Posterior Tibial Artery
Inferior popliteal space - beginning adductor hallucis
Begins at the inferior border of the popliteal space and ends at the origin of the abductor hallucis muscle
Linear Guide for the Posterior Tibial Artery
Popliteal space - between medial malleolus & calcaneus
A line drawn from the center of the popliteal space to a point midway between the medial malleolus and the calcaneus bone.
Anatomical Guide for the Posterior Tibial Artery
The groove behind and below the medial/inner malleolus (ankle joint).
Begins at the lower border of the popliteal space opposite the interval between the tibia and fibula.
Anatomical Limits for the Right Subclavian Artery
Behind sternoclavicular articulation - lateral first rib
Begins at a point behind the sternoclavicular articulation and extends to the lateral border of the first rib.
Anatomical Limits for the Left Subclavian Artery
2nd costal cartilage- 1st rib
Begins at the level of the 2nd costal cartilage and extends to the lateral border of the 1st rib.
Branches of the Subclavian Arteries
Upper limbs are supplied by the arteries arising from the subclavian arteries
Vertebral Artery
Internal Thoracic Artery
Thyrocervical Trunk
Costocervical Trunk
Vertebral Arteries
- Paired – right and left
- Provide blood supply to the posterior regions of the brain
- Pass through the foramen magnum and join to become the basilar artery, which is an upaired artery that ascends along the ventral midline of the brain to connect with the Circle of Willis (a cerebral arterial anastomoses, that unites the posterior blood supply of the brain with the anterior blood supply of the brain).
Anatomical Guide for the Axillary Artery
Along or just behind the medial border of the coracobrachialis muscle.
Anatomical Limits for the Axillary Artery
1st rib - teres major tendon
Begins at the lateral border of the first rib and extends to the lower border of the tendon of the teres major muscle.
Linear Guide for the Axillary Artery
Base of axillary space downward
A line drawn through the center of the base of the axillary space and parallel to the long axis of the upper extremity when abducted
Anatomical Guide for the Brachial Artery
Lies posterior to the medial border of the belly of the biceps brachii muscle
Anatomical Limits for the Brachial Artery
Teres major - antecubital fossa
Begins at the lower border of the tendon of the teres major muscle and extends just inferior to the antecubital fossa.
Linear Guide for the Brachial Artery
Base axillary space - antecubital fossa
A line drawn from the center of the base of the axillary space, to the center, inner bend of the elbow (antecubital fossa).
Anatomical Guide for the Radial Artery
