If the universal anatomical position were to be changed so that the palms were facing backward, how would this alter your description of the location of the palms and thumbs? a. Changing this position would mean that the palms and thumbs would now be facing posteriorly instead of anteriorly. This would make it difficult when referencing other parts of the body in relation to the hands. 2. Why is it important to have an anatomical position that is universally accepted? a. Describing different parts of the body should be something that is consistent across the world and other countries. It is crucial for doctors, surgeons and Emergency Medical Technicians to have a consistent point of reference in order to determine how they found the patient, what part of the body they are treating, what parts of the body are affected, etc. 3. How would the view of the thoracic cavity along the midsagittal plane be different than if it were viewed along a transverse plane? a. The thoracic cavity contains the heart and lungs. A midsagittal plane divides the body into equal right and left halves. This means that the view would show the heart and lungs essentially cut in half equally among each other. A transverse plane divides the body into superior and inferior parts. In this case, the heart and lungs would essentially be intact and we would be able to get a full anterior and posterior view. 4. Identify the four abdominopelvic quadrants and the organs that are found in each quadrant. a. Right Upper Quadrant (RUQ): large intestine, small intestine, gall bladder, liver b. Left Upper Quadrant (LUQ): stomach, spleen c. Right Lower Quadrant (RLQ): appendix, urinary bladder d. Left Lower Quadrant (LLQ): part of large and small intestine, part of urinary bladder 5. Why is the quadrant system important? a. It can be used to distinguish the basic locations of organs. If a patient complains of tenderness, pain or swelling, having a general understanding of where the organs are located can indicate what organ is being affected and how the patient should be treated. 6. The visceral pericardium covers the heart wall and the parietal pericardium lines the wall of the cavity. Both of these are serous membranes and they are responsible for producing watery fluid. Can you describe the potential problems that can occur if these secreted less watery fluid than normal? a. The fluid is secreted in order to allow the heart to pump properly without any friction. If the serous membranes secreted less fluid than normal, this could potentially lead to heart problems as the heart will continue to pump but with a lot of friction. If there continues to be a high amount of friction, this can lead to cardiac tissues being damaged and serious heart problems can arise. 7. What does it mean for a body to be in anatomical position? What is the importance? a. A body in anatomical position means that it is erect with the palms facing forward (anteriorly). This is important as it serves as a consistent point of reference which is crucial especially for doctors, physical therapists, Emergency Medical Technicians, surgeons, and everyone else in general. 8. Explain the meaning of the underlined anatomical terms. a. In the lower extremity, the rectus femoris muscle lies
anterior to the semitendinosus muscle. This means that the rectus femoris muscle is in front of the semitendinosus muscle. The semitendinosus muscle is found on the posterior side of the lower extremities. b. The liver is
superior to the small intestine. This means that the liver is above the small intestine. Because the small intestine is below the stomach, it is also known as being inferior to the stomach.
9. Describe the difference between a midsagittal plane and a parasagittal plane. a. A midsagittal plane divides the body into equal left and right hemispheres, whereas a parasagittal plane divides the body into unequal left and right parts. ...
