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.
Rationale: Food and drinks are never allowed in the lab
because they can become contaminated or cause accidents.
Long, loose hair must be pulled back to prevent it from
getting caught in equipment or dipping into hazardous
materials. A microscope hanging off the edge of a bench
poses a fall hazard.
,2. Describe the position of a subject's body when they are in
anatomical position.
Answer: Standing upright with feet flat on the ground, head
facing forward, arms at the sides with palms facing forward.
Rationale: Anatomical position is the standardized reference
position used in anatomy. The body is standing upright,
facing forward, with feet slightly apart and flat on the ground.
The arms are at the sides with palms facing forward
(supinated), and the head is level facing forward. This
position allows for consistent use of directional terms.
3. Which anatomical plane best describes a cut that divides
the body into equal left and right halves?
Answer: Mid-Sagittal Plane.
Rationale: The mid-sagittal (median) plane runs exactly
through the midline of the body, dividing it into equal left
and right halves. A general sagittal plane divides the body
into left and right portions but not necessarily equal halves.
4. Which anatomical plane best divides the body into anterior
and posterior portions?
Answer: Frontal Plane.
Rationale: The frontal (coronal) plane divides the body into
anterior (front) and posterior (back) sections. The transverse
plane divides it into superior and inferior sections.
5. Which anatomical plane divides the body into superior and
inferior sections?
Answer: Transverse Plane.
, Rationale: The transverse (horizontal) plane runs
horizontally, dividing the body into upper (superior) and
lower (inferior) portions.
6. When comparing the relationship of the eyes to the
occipital (back portion) region of the head, which term best
describes the occipital region?
Answer: Posterior/Dorsal.
Rationale: The occipital region is at the back of the head, so
it is posterior (or dorsal) to the eyes, which are anterior (or
ventral).
7. When looking at the body in anatomical position, which
statement best describes the relationship of the knee to the
ankle?
Answer: The knee is superior and proximal to the ankle.
Rationale: The knee is above the ankle (superior) and closer
to the trunk than the ankle is (proximal).
8. Which of the following lines the lungs?
Answer: The visceral pleura.
Rationale: The visceral pleura is the serous membrane that
directly covers the lungs. The parietal pleura lines the thoracic
cavity wall.
9. The crus is part of which skeletal division?
Answer: The appendicular division.
Rationale: The crus (leg) is part of the lower limb, which
belongs to the appendicular skeleton.
, 10. Which of the following statements is false?
Answer: The thoracic cavity contains 2 subdivisions.
Rationale: The thoracic cavity actually contains 3
subdivisions: the left and right pleural cavities and the
mediastinum (which contains the pericardial cavity).
11. Describe the supine position.
Answer: Lying on the back, face upward.
Rationale: Supine is a body position where the patient lies
flat on their back with the face and torso facing upward.
12. Describe the proper way to carry a microscope.
Answer: Place one hand under the base while the other hand
braces the arm.
Rationale: This two-handed technique provides stable
support and prevents the microscope from being dropped or
damaged.
13. What portion of the light microscope adjusts the amount
of light that passes through the light source?
Answer: The diaphragm.
Rationale: The diaphragm (or iris) controls the amount of
light passing through the specimen. The illuminator is the
light source itself, and the oculars are the eyepieces.
14. The objective magnification is 4x. The ocular
magnification is 10x. What is the total magnification?
Answer: 40x.
