Which artery is located in the upper arm and can be felt on the inside of the upper arm?

1. Carotid artery

2. Radial artery

3. Femoral artery

4. Brachial artery

The correct answer is: Brachial artery

The brachial artery is the correct choice as it is the major blood vessel supplying blood to the arm and can be palpated on the inside of the upper arm, specifically in the area between the biceps and triceps muscles. It is the continuation of the axillary artery after it passes the lower border of the teres major muscle and runs down the arm, where it eventually bifurcates into the radial and ulnar arteries at the elbow. Understanding the location and function of the brachial artery is crucial for those in emergency medical situations because it is commonly used for taking blood pressure readings and assessing circulation in the arm. Its palpable nature in the upper arm provides a practical site for medical professionals to assess vascular conditions or perform diagnostic procedures.
