PORTAGE LEARNING BIOD 151 LAB EXAM
QUESTIONS & ANSWERS (COMPILED FROM
VERIFIED SOURCES)
LAB SAFETY & ANATOMICAL TERMINOLOGY
Question 1
Susan Smith is a participant in an Anatomy and Physiology lab
class. She walked into lab carrying a bagged lunch and has long
blonde hair that is not pulled back. Her microscope is partially
hanging off the edge of her lab bench. List two lab safety
concerns you notice in this scenario.
Answer: Susan brought food into the lab; Susan did not pull her
hair back
Rationale: Food and drinks are never allowed in the lab because
they can become contaminated or cause accidents. Long, loose
hair must always be pulled back to prevent it from getting caught
in equipment or dipping into hazardous materials. Additionally, a
microscope hanging off the edge of a bench poses a fall hazard .
Question 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 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 .
Question 3
Which of the following anatomical planes best describes a cut that
divides the body into equal left and right halves?
Answer: Mid-Sagittal Plane
Rationale: The mid-sagittal (median) plane is a vertical plane that
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 .
Question 4
Which anatomical plane best divides the body into anterior and
posterior portions?
Answer: Frontal Plane
Rationale: The frontal plane, also called the coronal plane, is a
vertical plane that runs from side to side, dividing the body into
anterior (front) and posterior (back) portions .
Question 5
When comparing the relationship of the eyes to the occipital
region of the head, which terms best describe the occipital
region?
Answer: Dorsal and posterior
Rationale: The occipital region is at the back of the head. It is
both dorsal (toward the back) and posterior (behind). Ventral and
anterior refer to the front side of the body .
, Question 6
In anatomical position, are the hands in pronation or supination?
Answer: Supination
Question 7
Which directional term describes the position of the elbow
relative to the shoulder?
Answer: Distal
Rationale: Distal means farther from the point of attachment or
the trunk of the body. The elbow is distal to the shoulder .
CELLULAR BIOLOGY & TISSUES
Question 8
Which of the following represents the correct sequence from
simplest to most complex in the structural hierarchy of the human
body?
Answer: Chemical → Cellular → Tissue → Organ → Organ system
→ Organism
Rationale: The structural hierarchy begins at the chemical level
(atoms and molecules), progresses to the cellular level (cells), then
tissue level (groups of similar cells), organ level (structures of two
or more tissue types), organ system level (related organs working
together), and finally the organism level .
Question 9
Which organelle is responsible for energy production in the cell?
