BIO 221 Lab 1 - KEY.docx

Lab 1: Anatomical Scavenger Hunt Source: Cynthia Harley, Ph.D. Name: _____ KEY _____________ Introduction You are allowed to use your books, notes, models, and even the Internet for this exercise. The purpose of this exercise is to make you more comfortable with the anatomical terminology that we learned in chapter 1 and that we will be using throughout the next two semesters. Keep in mind that some terms may be more appropriate than others for the same answer. For example, if I asked where your nose was located relative to your ears, “medial” would be appropriate, but if I asked which plane divides your nose from your ears, you’d say “sagittal.” You can use your existing knowledge of the human body or the anatomical models in Visible Body to answer these questions. Of course, you are also allowed to use the book and class notes. Required Materials  Visible Body’s Human Anatomy Atlas app  Articulated skeleton (optional)  Whole body anatomy model (optional)  Textbook (optional) Anatomical Terminology Questions Answer the following questions and turn in your answers for this week’s lab grade. 1.

What abdominopelvic region is this? ___________ left hypochondriac __________________ 15. A patient who was in a knife fight suffered a 2-inch stab wound to his back. The knife entered through the posterior thorax along the midsagittal plane and entered the posterior aspect. What structure in the posterior aspect would have been injured by this wound? Thoracic vertebrae & spinal cord (most likely) 16. The urinary bladder is found within the _______ hypogastric ____________________ region. 17. The _______ pericardial _______ cavity contains the heart, and it is surrounded by a membrane called the _________ pericardium _______________. 18. Name a structure that is located posterior and inferior to the liver. Kidney (multiple correct possible answers) 19. Name a structure that is on the ventral side of the heart, located more laterally within the axial region. Left lung or left ribs, pectoralis major, mammary gland (multiple correct possible answers) 20. Name a structure that is located toward the dorsal side of the body, lateral and superior to the hamstring but inferior to the heart.
