Instructions: Address each question below as it relates to the case study given.

A patient was brought to the Emergency Department by ambulance with two arrow wounds. One arrow is still in the patient on the left side; entering anteriorly between the 7th and 8th ribs in a 15 degree angle, the arrow head protruding posteriorly. The second wound is located in the posterior cervical triangle.

Question 3

• Describe the trajectory of the first arrow using directional terms and anatomical planes.
• Identify and describe the organs and any other membranes that may have been affected by the first arrow.
