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.

Answer the following questions using a minimum of five (5) academic references (you many not use Wikipedia, blogs, or
other informal sources.) Use APA format in-text citations in your answers and include a reference page.

Question 1
 What serosal cavities have been penetrated by the first arrow?
 Explain the location, the microscopic cellular components of the serous membrane, and the purpose of
the serous membrane.

Question 2
 Describe the Autonomic Nervous System and explain how the patient’s ANS reacts to the arrow attack
and how it will affect the patient’s vital signs (P, BP, R, T).
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.
Question 4
 Describe the cardiovascular system and explain how both the pulmonary and systemic circuits will be
affected by both arrows.
 Include the effect on the Hematocrit and Hemoglobin values.
Question 5
 Identify the possible neuromuscular effects of the second arrow and explain your reasoning.
 Describe the components of a neuromuscular junction including key organelles.
Question 6
 Identify and describe the three labeled tissue types found in the tracheal slide (Slide 2) below. Include
the subcategories and cellular components for each tissue type.
 How will the injuries affect this area?
