Question
a knife wound penetrates the superficial vein that terminates in the axillary vein. The blood vessel from which the bleeding occurs is :a) median cubital veinb) basilic veinc) dorsal venous archd) cephalic vein
Solution
The answer is b) basilic vein.
Here's the step-by-step reasoning:
-
The axillary vein is located in the armpit (axilla). It receives blood from the basilic vein and the cephalic vein.
-
The cephalic vein runs up the lateral side of the arm, from the hand to the shoulder, where it empties into the axillary vein.
-
The basilic vein runs up the medial side of the arm, from the hand to the axilla, where it also empties into the axillary vein.
-
The median cubital vein is a superficial vein of the upper limb. It does not directly terminate in the axillary vein.
-
The dorsal venous arch is a superficial vein in the hand. It does not directly terminate in the axillary vein.
-
Given the information in the question, if a knife wound penetrates a superficial vein that terminates in the axillary vein, the most likely vein affected would be the basilic vein, as it is a superficial vein that directly terminates in the axillary vein.
