BIOL251: Human Anatomy & Physiology I w/Lab
Comprehensive Test Bank – Modules 1–7 (100 Questions)
Module 1: Introduction to Anatomy & Physiology and
Homeostasis
Question 1. The study of the structure of body parts and their relationships to one
another is known as:
A. Physiology
B. Anatomy
C. Histology
D. Cytology
Rationale: Anatomy is the scientific discipline that investigates the structure of the
body. Physiology is the study of the function of those structures.
Question 2. The maintenance of a stable internal environment is called:
A. Metabolism
B. Homeostasis
C. Responsiveness
D. Adaptation
Rationale: Homeostasis refers to the dynamic state of equilibrium or balance in the
internal environment of the body, maintained by regulatory processes.
Question 3. Which of the following represents the highest level of structural
organization in the human body?
A. Organ system
B. Organ
C. Tissue
D. Organismal
Rationale: The organismal level represents the sum total of all structural levels
working together to sustain life, making it the highest and most complex level.
,Question 4. In a homeostatic control system, which component detects a change in
the variable?
A. Control center
B. Effector
C. Receptor
D. Stimulus
Rationale: The receptor is a sensor that monitors the environment and responds to
changes, called stimuli, by sending input to the control center.
Question 5. The term meaning "toward the head" is:
A. Inferior
B. Caudal
C. Posterior
D. Superior
Rationale: Superior (cranial) means toward the head end or upper part of a
structure or the body.
Question 6. A cut dividing the body into superior and inferior portions is made on
the:
A. Sagittal plane
B. Frontal plane
C. Transverse plane
D. Midsagittal plane
Rationale: A transverse (or horizontal) plane runs horizontally, dividing the body
into upper (superior) and lower (inferior) parts.
Question 7. The heart is located in which body cavity?
A. Cranial cavity
B. Abdominal cavity
C. Thoracic cavity
D. Pelvic cavity
, Rationale: The thoracic cavity is the superior division of the ventral body cavity,
enclosed by the rib cage and containing the heart and lungs.
Question 8. The visceral pericardium is the part of a serous membrane that:
A. Lines the fibrous pericardium
B. Covers the surface of the heart
C. Lines the thoracic wall
D. Is found only in the abdominal cavity
Rationale: The visceral serous membrane adheres directly to the surface of the
organ. For the heart, this layer is called the visceral pericardium (epicardium).
Question 9. Blood clot formation is an example of which type of feedback?
A. Positive feedback
B. Negative feedback
C. Neutral feedback
D. Dynamic feedback
Rationale: Positive feedback amplifies an initial stimulus. In blood clotting, each
step releases chemicals that accelerate the next step until a clot is formed.
Question 10. The anatomical term for "armpit" is:
A. Olecranal
B. Antecubital
C. Axillary
D. Brachial
Rationale: Axillary is the correct anatomical term referring to the armpit region.
Question 11. Which directional term means "closer to the origin of a limb"?
A. Distal
B. Lateral
C. Proximal
D. Medial
