1. Susan Smith is a participant in an Anatomy and Physiology lab class. Susan walked into lab today
carrying a bagged lunch that she brought to eat following class. She has long blonde hair that is not
pulled back. Today in class, you are reviewing basic microscopy and you notice that Susan's microscope
is partially hanging off the edge of her lab bench. Given what you learned from the lab video, list two lab
safety concerns you notice in the above scenario.
Answer: Susan brought food into the lab; Susan did not pull her hair back; Susan does not have the
microscope safely secured on the lab bench.
2. Describe the position of a subject's body when they are in anatomical position.
Answer: When a person is standing in anatomical position, they are standing upright with feet flat on
the ground. Head is facing forward. Arms are at the sides with palms facing forward.
3. When comparing the relationship of the eyes to the occipital (back portion) region of the head, which
of the following terms best describes the occipital region?
• a. Ventral
• b. Dorsal
• c. Anterior
• d. Posterior
• e. a. and c.
• f. b. and d.
Answer: f. b. and d. (The occipital region is both dorsal and posterior to the eyes.)
4. When looking at the body in anatomical position, which of the following statements best describes
the relationship of the leg to the ribs?
• a. The leg is distal to the ribs
• b. The leg is inferior to the ribs
• c. The leg is lateral to the ribs
• d. The leg is superficial to the ribs

Answer: Proximal.
11. The elbow is ________ to the wrist.
Answer: Proximal.
12. The nose is ________ to the ears.
Answer: Medial.
13. In anatomical position, the palms face ________.
Answer: Forward (anteriorly).

17. When you are looking at a slide through the microscope, which adjustment knob should you use
first?
Answer: Coarse adjustment knob (to bring the specimen into rough focus).
18. List two pieces of personal protective equipment (PPE) commonly required in lab.
Answer: Lab coat, safety goggles, gloves (any two).
19. What should you do if you accidentally break a glass slide?
Answer: Notify the instructor and dispose of the glass in a designated sharps container; do not pick up
with bare hands.

24. The ________ controls the amount of light passing through the specimen.
Answer: Iris diaphragm.
25. Once you move to the 40x objective, you should only use the ________ adjustment knob.
Answer: Fine.
26. What is the function of immersion oil when using a 100x objective?
Answer: Immersion oil reduces light refraction and improves resolution.
27. Which part of the microscope holds the slides in place?
Answer: Stage clips (or mechanical stage).
28. Before putting the microscope away, you should always ________.
Answer: Turn the light off, lower the stage, and set the lowest objective (4x) in place.
29. If a specimen appears too dark, you should ________.
Answer: Open the iris diaphragm or increase the light intensity.

________ lens by the magnification of the ________ lens.
Answer: Ocular; objective.
