Where is the radial artery located?

The radial artery is situated in the lower arm, specifically along the lateral (thumb side) aspect of the forearm. It is a major blood vessel that supplies oxygenated blood to the hand and wrist. The radial artery is easily palpated at the wrist, making it a common location for checking pulse and assessing blood circulation. Understanding the anatomical location of the radial artery is essential for medical professionals, particularly for procedures such as taking a pulse or during venipuncture.

In contrast, the upper arm is served by different arteries such as the brachial artery, while the lower leg has arteries like the femoral and popliteal arteries. The neck contains carotid arteries, which are responsible for supplying blood to the brain. Recognizing these differences is crucial for accurately identifying the correct answers in anatomical questions.
