Which term relates to the arm (brachium), as in the brachial artery?

• A. Brachial
• B. Carotid
• C. Antecubital
• D. Blood Pressure

Answer: (A)

In anatomy, many terms come from Latin roots that name locations on the body. The root brachium means arm, so terms built from brach- or brachial describe structures in the upper limb. The brachial artery is the main blood vessel of the upper arm, running through that region and supplying the arm with blood. That makes the term that relates to the arm the brachial. Carotid refers to the neck area (carotid arteries in the neck). Antecubital describes the front of the elbow, not the arm as a whole. Blood pressure is a measurement, not a location or region of the body.
