D) exercise and nutrition. - ANSWER -Answer: C
Explanation: A) INCORRECT. Anatomy is the study of body structure.
B) INCORRECT. Physiology is the study of how the body should work normally.
C) CORRECT. Physiology is the study of body function.
D) INCORRECT. Physiology is not directly related to exercise and nutrition.
2) In relation to anatomy, the term topography means:
A) the study of the skin.
B) external landmarks of body structures.
C) blood pressure fluctuations.
D) key elements of the central nervous system. - ANSWER -Answer: B
Explanation: A) INCORRECT. The study of skin is known as dermatology.
B) CORRECT. One of the ways to find organs or body structures is through topography, or
external landmarks, such as notches or bumps.
C) INCORRECT. The term topography is not related to blood pressure.
D) INCORRECT. Key elements of the central nervous system are not referred to as topography.
3) Which of the following organs functions as a reservoir for blood that can be used in case of
blood loss?
A) Liver
B) Spleen
C) Thyroid gland
,D) Heart - ANSWER -Answer: B
Explanation: A) INCORRECT. The liver produces bile to assist in the breakdown of fats and
assists in the metabolism of various substances in the body.
B) CORRECT. The spleen is a reservoir for reserves of blood.
C) INCORRECT. The thyroid gland regulates certain hormones and it is not related to the
storage of blood.
D) INCORRECT. The heart pumps blood, it is not able to store it.
4) Which of the following structures or tissues is not part of the musculoskeletal system?
A) Ligaments
B) Acetabulum
C) Fat
D) Tendons - ANSWER -Answer: C
Explanation: A) INCORRECT. Ligaments are the tissues that connect bone to bone.
B) INCORRECT. The acetabulum is the socket of the hip joint.
C) CORRECT. Fat, also called adipose tissue, is not part of the musculoskeletal system.
D) INCORRECT. Tendons are the fibrous structures that connect muscle to bone.
5) Which of the following structures do not form part of the thorax?
A) Sternum
B) Ribs
C) Manubrium
D) Ischium - ANSWER -Answer: D
Explanation: A) INCORRECT. The sternum is part of the chest, or thorax.
B) INCORRECT. The thorax, or chest, contains ribs.
C) INCORRECT. The manubrium is the superior portion of the sternum, which is in the thorax.
D) CORRECT. The lower, posterior of the pelvis is called the ischium.
6) What are the two most easily injured portions of the spine?
A) Sacral and coccygeal
B) Cervical and thoracic
C) Cervical and lumbar
, D) Lumbar and sacral - ANSWER -Answer: C
Explanation: A) INCORRECT. The sacral and coccygeal portions of the spine are strong and not
easily injured.
B) INCORRECT. Although the cervical spine can be easily injured, the thoracic spine is
supported by the rib cage and less prone to injury.
C) CORRECT. The cervical spine can be easily injured due to the size and weight of the head,
and the lumbar spine is hurt more often because it is unsupported by other parts of the
skeleton.
D) INCORRECT. The lumbar spine is unsupported and can be injured by numerous mechanisms,
but the sacral spine is solid and strong.
7) Which of the following terms describes the heart muscle's ability to generate its own
electrical impulses?
A) Contractility
B) Conductivity
C) Automaticity
D) Irritability - ANSWER -Answer: C
Explanation: A) INCORRECT. A muscle's ability to contract is called contractility; it is not related
to electricity generation.
B) INCORRECT. Conductivity is the degree to which a material conducts electricity, not
generates it.
C) CORRECT. The ability of the heart to generate and conduct electrical impulses on its own is
called automaticity.
D) INCORRECT. Irritability does not describe the heart muscle's ability to generate electrical
impulses.
8) Which of the following respiratory processes requires the active use of muscles?
A) Inhalation
B) Bifurcation
C) Exhalation
D) Gas exchange - ANSWER -Answer: A
Explanation: A) CORRECT. The muscles of the diaphragm and ribs are necessary for inhalation.
B) INCORRECT. Bifurcation is the anatomic term used to describe when a single body structure
splits into two, such as when the trachea splits and goes into each lung.
