Question

The correct sequence in which the branches of femoral artery arise from main trunk is:
(A). Pudendoepigastric trunk
(B). Anterior femoral artery
(C). Saphenous artery
(D). Deep femoral artery
Choose the correct answer from the options given below:

• A. (A), (B), (C), (D).
• B. (A), (D), (B), (C).
• C. (A), (B), (D), (C).
• D. (A), (C), (B), (D).

Hint:

To remember this vascular branching order from proximal to distal, use the mnemonic:
Pudendoepigastric \(\rightarrow\) Deep femoral \(\rightarrow\) Anterior femoral \(\rightarrow\) Saphenous.

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
The external iliac artery continues into the thigh as the femoral artery after passing through the vascular lacuna.
Tracing the sequential branching of the femoral artery from proximal to distal is a key part of regional hindlimb anatomy.

Step 2: Detailed Explanation:
Let us trace the major branches arising from the external iliac and femoral trunk in order from proximal (closest to the body) to distal (farthest):
1. Pudendoepigastric trunk (A): This is the most proximal branch listed, typically arising at the transition zone from the deep femoral artery or directly from the trunk near the vascular lacuna.
2. Deep femoral artery (D): This major artery branches off early in the proximal thigh to supply the deep adductor muscles of the hip.
3. Anterior femoral artery (B): Also known as the lateral circumflex femoral artery, this branches off next to supply the quadriceps femoris muscle group on the cranial aspect of the thigh.
4. Saphenous artery (C): This is a distal branch that arises near the knee joint, traveling superficially down the medial side of the leg to supply the skin and distal foot.
This proximal-to-distal sequence corresponds to the order: (A) \(\rightarrow\) (D) \(\rightarrow\) (B) \(\rightarrow\) (C).

Step 3: Final Answer:
The correct sequence is (A), (D), (B), (C). This corresponds to option (B).
