In the image described, the artery being palpated lies posterior to the medial malleolus and anterior to the Achilles (calcaneal) tendon. This is the classic anatomical location for palpation of the posterior tibial artery.

Posterior tibial artery is palpated:
- Behind the medial malleolus
- Anterior to the calcaneal tendon
- Best felt with slight inversion of the foot to relax the flexor retinaculum

Other options:

1. Dorsalis pedis artery: Palpated on the dorsum of the foot, lateral to the extensor hallucis longus tendon—not near the medial malleolus.
2. Popliteal artery: Palpated in the popliteal fossa, behind the knee—not near the ankle.

3. Anterior tibial artery: It courses in the anterior compartment and becomes dorsalis pedis distally—again not behind the medial malleolus.

Here is a concise table showing different arteries and their palpation locations for quick clinical reference:

Artery	Palpation Location
Radial artery	Lateral aspect of the wrist (thumb side), just lateral to the flexor carpi radialis
Ulnar artery	Medial aspect of the wrist, lateral to the flexor carpi ulnaris tendon
Brachial artery	Medial to biceps tendon in antecubital fossa OR mid-arm medial groove
Axillary artery	Deep in the axilla, against the humerus
Carotid artery	Medial to sternocleidomastoid at level of thyroid cartilage
Femoral artery	Midpoint of inguinal ligament (between ASIS and pubic symphysis)
Popliteal artery	Deep in popliteal fossa with knee flexed, between hamstring tendons
Posterior tibial artery	Posterior to medial malleolus, between medial malleolus and Achilles tendon
Dorsalis pedis artery	Dorsum of foot, lateral to extensor hallucis longus tendon
Temporal artery	Anterior to the ear, above the zygomatic arch
