Comprehensive Anatomy and Physiology
Exam Prep 2025
Anatomy is best defined as
A) The study of body functions
B) The study of tissues only
C) The study of diseases
D) The study of the structure of an organism
Rationale: Anatomy deals with structure. Physiology is function, pathology is disease, and
histology focuses on tissues only.
The simplest level of organization in the human body is the
A) Organ
B) Organ system
C) Tissue
D) Cell
Rationale: The cell is the basic structural and functional unit of life. Tissues and organs are
made of cells, and organ systems consist of organs.
Which of the following is an example of a negative feedback loop?
A) Childbirth contractions
B) Blood clot formation
C) Regulation of body temperature
D) Lactation
Rationale: Negative feedback restores balance (e.g., temperature regulation). Childbirth and
lactation are positive feedback loops.
Which of the following is an example of a positive feedback loop?
A) Blood glucose regulation
B) Childbirth contractions
C) Regulation of pH
D) Thermoregulation
Rationale: In positive feedback, the response amplifies the stimulus. Contractions during
childbirth intensify until delivery.
The two major body cavities are
A) Cranial and spinal
B) Abdominal and pelvic
C) Pleural and pericardial
D) Thoracic cavity and abdominopelvic cavity
Rationale: The body is divided into dorsal (cranial and spinal) and ventral cavities, with the
ventral further subdivided into thoracic and abdominopelvic.
,The correct description of the anatomical position is
A) Lying face down, palms up
B) Standing upright, arms at sides, palms facing inward
C) Sitting, arms crossed, head down
D) Standing upright, facing forward, arms at the sides with palms facing forward
Rationale: This is the universally accepted reference position in anatomy.
The three major planes of the body are
A) Oblique, lateral, longitudinal
B) Vertical, horizontal, diagonal
C) Sagittal, frontal (coronal), and transverse
D) Superior, inferior, medial
Rationale: Sagittal divides left/right, frontal divides anterior/posterior, transverse divides
superior/inferior.
A group of cells working together to perform a specific function is called a
A) Molecule
B) Organ
C) Organ system
D) Tissue
Rationale: Tissues are groups of similar cells with a common function. Organs are built from
tissues.
The term "lateral" describes a body part that is
A) Closer to the midline
B) Further away from the midline
C) Above another part
D) Toward the surface of the body
Rationale: Lateral means away from the midline, while medial means closer to it.
The midsagittal plane divides the body into

Rationale: The midsagittal plane runs exactly down the midline, splitting the body into equal
halves.
The ventral cavity is
A) Found only in the skull
B) One of the main cavities of the body
C) Another name for the dorsal cavity

cavity houses the brain and spinal cord.
,The pleural cavities are

Rationale: Coronal (frontal) divides the body into anterior and posterior parts.
The pelvic cavity is separated from the abdominal cavity by
A) The pleura
B) The pericardium

Rationale: The diaphragm separates the thoracic cavity from the abdominopelvic cavity
(abdominal + pelvic).
The right hypochondriac region is located
A) Completely in the right upper quadrant of the abdomen
B) In the lower abdomen
C) In the left lower quadrant
D) Near the umbilical region only
Rationale: The right hypochondriac region lies under the ribs in the upper right abdominal
quadrant.
The left hypochondriac region is located
A) In the right upper quadrant
B) Completely in the left upper quadrant of the abdomen
C) In the left lower quadrant
D) Near the pelvic cavity
Rationale: The left hypochondriac region is in the upper left quadrant, beneath the ribs.
The right lumbar region is located
A) Inferior to the right iliac region
, B) Superior to the right iliac region
C) Directly above the umbilical region
D) In the left lower quadrant
Rationale: Lumbar regions are in the mid-abdomen, above the iliac (inguinal) regions.
The dorsal cavity includes
A) The pleural cavity
B) The abdominal cavity
C) The spinal cavity
D) The pelvic cavity
Rationale: The dorsal cavity houses the cranial and spinal cavities.
The brain is located in the
A) Abdominal cavity
B) Thoracic cavity
C) Ventral cavity
D) Dorsal cavity
Rationale: The brain sits in the cranial cavity, which is part of the dorsal cavity.
In a feedback loop, the part of the system that detects a change in the controlled condition is
called the
A) Effector
B) Sensor
C) Stimulus
D) Integrator
Rationale: The sensor (or receptor) detects the stimulus. The effector carries out the corrective
action.
In a feedback loop, the part of the system that carries out the response is called the
A) Sensor
B) Effector
C) Stimulus
D) Control center
Rationale: The effector brings about the change to restore balance.
The formation of a blood clot is an example of
A) A positive feedback loop
B) A negative feedback loop
C) Homeostasis failure
D) Local control
Rationale: Blood clotting amplifies itself until the wound is sealed — a classic positive
feedback.
Regulation of body temperature is an example of
A) Positive feedback
B) Reflex control
