Answers to Quick Check Questions
Patton: Structure & Function of the Body, 17th Edition
Chapter 01: Introduction to the Body
Answers to Quick Check Questions
Quick Check set 1 (p. 5)
1. Anatomy is the study of the structure of an organism and the relationships of its parts.
Physiology is the study of the functions of living organisms and their parts.
2. The major levels of organization in the body are chemical—cellular—tissue—organ—organ
system—organism.
3. A tissue is an organization of many similar cells that act together to perform a common
function. Organs are larger and more complex than tissues. An organ is a group of several
different kinds of tissues arranged so that they can together act as a unit to perform a special
function.
4. Anatomical parts have structures that are suited for specific functions. Each structure has a
particular size, shape, form, or position in the body that relates directly to its ability to
perform a specialized or unique activity or function.
Quick Check set 2 (p. 7)
1. The anatomical position is a reference position that gives meaning to the directional terms
used to describe the body parts and regions. The body is in an erect or standing posture with
the arms at the sides and palms turned forward. The head also points forward, as do the feet,
which are slightly apart.
2. The right and left sides of the body roughly mirror each other. This is referred to as bilateral
symmetry.
3. Supine and prone are terms used to describe the position of the body lying down. In the
supine position, the body is lying face upward. In the prone position, the body is lying face
downward.
4. Anatomical directions are listed in sets of opposite pairs to describe relative positions of body
parts and to refer to an organ in relation to other structures.
Quick Check set 3 (p. 10)
1. Section is a term used to describe how the body as a whole is subdivided or “cut” into smaller
segments (e.g., sagittal, frontal, transverse).
2. Ventral and dorsal body cavities
3. The lower part of the ventral cavity includes the abdominal cavity and pelvic cavity. Because
no physical partition separates them, the two together actually form one large cavity referred
to as the abdominopelvic cavity. The abdominopelvic region is also further subdivided into
nine regions or four quadrats for ease in medical description (see diagram in text).
4. Both are used to describe the same area, so there is no difference. Upper and lower are often
used to name quadrants rather than superior and inferior. This reflects the more common
usage found in many clinical environments where a mix of informal and technical
terminology is common.

Answers to Quick Check Questions
Quick Check set 4 (p. 12)
1. The axial portion of the body consists of the head, neck, and torso or trunk. The appendicular
portion consists of the upper and lower extremities.
2. The upper extremity is divided into arm, forearm, wrist, and hand components. The lower
extremity is the leg, ankle, and foot components. You may also note some additional
delineations that are sometimes used for the upper and lower extremities by reviewing the
diagrams and tables of the axial and appendicular skeleton in the chapter.
Quick Check set 5 (p. 16)
1. Homeostasis is what physiologists call the relative constancy of the internal environment.
Because the activities of cells and external disturbances are always threatening internal
stability or homeostasis, the body must constantly work to maintain that “balance” or
stability.
2. A feedback loop is a basic type of control system in the body. It works to restore
homeostasis. An example can be seen in how our body restores body temperature when we
become chilled. A sensor (nerve ending) detects a change in temperature. Information from
the sensor feeds back to a control center (brain) that compares the actual temperature to the
normal temperature and responds by activating an effector (muscle shivering).
3. Negative feedback loops oppose, or negate, a change in a controlled condition. Instead of
opposing change in the internal environment and causing a “return to normal,” positive
feedback loops cause an ever-increasing rate of events to occur until something stops the
process.
4. Negative feedback can dangerously turn into positive feedback, possibly causing a deadly
shift in body function. An example of this is in the case of severe hemorrhage. This condition
will cause a drop in blood pressure, causing the heart to beat faster in an attempt to return the
blood pressure back to setpoint. The increase in heart rate, however, causes a further blood
loss and continued drop in blood pressure, and thus an even faster heart rate, in an ever-
increasing cycle that can rapidly turn deadly.
Quick Check set 6 (p. 17)
1. Organisms that make up the human microbiome include bacteria, fungi, viruses and other
microscopic organisms. Communities of these microbes can be found on the body’s surface
(skin) and internal spaces (such as digestive, respiratory and urinary tubes).
2. Eubiosis means “good life conditions” and is used to describe when the human
microbiome is functioning to maintain wellness. Dysbiosis means “bad life conditions” and
describes when the human microbiome is imbalanced and can lead to illness or death.
3. Probiotic products contain beneficial bacteria, but prebiotic and postbiotic products do
not. Prebiotic products contain nutrients and fiber those beneficial bacteria need to survive.
Postbiotic products contain the kinds of byproducts produced by beneficial bacteria when
consuming prebiotics All three of these can be provided naturally with a healthy diet, but
supplements containing one or more of them can help treat dysbiosis and thus maintain
homeostasis.
