This question is a three part question. When answering each of the three parts of this question, please be sure to properly label your answers to include “1”, “2”, and “3” so as to ensure your instructor can determine the individual answers to each of the three parts. If you do not label your answers to the individual parts of the question, then no credit shall be awarded. PART 1: Identify the structure labeled “A” in the image below at left.  PART 2: Give the specific name of both the arteries and the veins that penetrate the depth of the structure labeled “A” in the image below at left.  PART 3: Identify the structure labeled “B” in the image below at right.

This question is a two part question. When answering each of the two parts of this question, please be sure to properly label your answers to include “1” and “2” so as to ensure your instructor can determine the individual answers to each of the two parts.
