SECTION 1: INTRODUCTION TO ANATOMY & PHYSIOLOGY
(Questions 1-15)
1. Which level of structural organization is defined as a group of similar cells
working together to perform a specific function?
A) Chemical level
B) Cellular level
C) Tissue level
D) Organ level
,Answer: C) Tissue level
Explanation: A tissue is defined as a group of similar cells that work together to
perform a common function. The chemical level involves atoms and molecules, the
cellular level involves individual cells, and the organ level involves multiple
tissues working together.[reference:0]
2. Which feedback mechanism counteracts a change in a physiological variable to
bring it back to its baseline setpoint?
A) Positive feedback
B) Negative feedback
C) Feed-forward regulation
D) Coagulation cascade
Answer: B) Negative feedback
Explanation: Negative feedback reverses a deviation from the setpoint to maintain
homeostasis. Positive feedback amplifies the change (e.g., childbirth, blood
clotting).[reference:1]
3. A clinician makes an anatomical slice that divides the human brain into equal
left and right halves. Which specific plane was used?
A) Frontal plane
B) Midsagittal plane
C) Parasagittal plane
D) Transverse plane
,Answer: B) Midsagittal plane
Explanation: A midsagittal (median) plane cuts directly down the midline,
producing equal left and right halves. A parasagittal plane divides into unequal
left and right portions.[reference:2]
4. Which directional term correctly describes the position of the urinary bladder
relative to the stomach?
A) Superior
B) Inferior
C) Anterior
D) Posterior
Answer: B) Inferior
Explanation: The bladder is located lower down, or closer to the feet, than the
stomach. Inferior means "below" or "toward the feet."[reference:3]
5. The urinary bladder and the internal reproductive organs are located within
which specific body cavity?
A) Abdominal cavity
B) Pelvic cavity
C) Thoracic cavity
D) Cranial cavity
Answer: B) Pelvic cavity
Explanation: The pelvic cavity is the inferior portion of the abdominopelvic
cavity and contains the urinary bladder, internal reproductive organs, and
, rectum.[reference:4]
6. Which abdominopelvic region is located directly superior to the umbilical
region?
A) Epigastric region
B) Hypogastric region
C) Right lumbar region
D) Left iliac region
Answer: A) Epigastric region
Explanation: The epigastric region is located superior (above) to the umbilical
region. The hypogastric region is inferior (below) the umbilical region.[reference:5]
7. The study of the function of body structures is called:
A) Anatomy
B) Physiology
C) Histology
D) Cytology
Answer: B) Physiology
Explanation: Physiology is the study of how body structures function. Anatomy is
the study of structure, histology is the study of tissues, and cytology is the
study of cells.
8. Which of the following is an example of a positive feedback mechanism?
A) Regulation of blood glucose levels
