BIOL 319 Exam 1,2,3 and Final Bundle
with complete solutions.
Questions 1-50: Exam 1 Material
1. Define Anatomy.
A. The scientific study of the function of living things
B. The scientific discipline that investigates the body's structures
C. The study of tissues at the microscopic level
D. The medical science dealing with disease processes
Correct ,,,answer,,,: B. The scientific discipline that investigates the body's
structures
Rationale: Anatomy focuses on form and structure of body parts—what things look
like and where they are located. Physiology studies function, not anatomy .
2. Define Developmental Anatomy.
A. Studies structural changes from conception to adulthood
B. Focuses on changes caused by disease
C. Examines cellular structures only
D. Studies only adult body structures
,Correct ,,,answer,,,: A. Studies structural changes that occur between
conception and adulthood
Rationale: Developmental anatomy tracks structural changes across the lifespan,
with embryology as a subspecialty focusing on the first 8 weeks .
3. Define Embryology.
A. Study of tissues under a microscope
B. Study of structural changes from conception to end of 8th week
C. Study of organ systems throughout life
D. Study of cellular metabolism
Correct ,,,answer,,,: B. Subspecialty of developmental anatomy studying
changes from conception to the end of the 8th week of development
Rationale: Embryology specifically examines prenatal development during the
embryonic period, which concludes at week 8 .
4. Define Cytology.
A. Study of tissues
B. Study of organ systems
C. Study of structural features of cells
D. Study of gross anatomical structures
Correct ,,,answer,,,: C. Examines the structural features of cells
Rationale: Cyto- refers to cells; cytology is the microscopic study of individual cell
structure .
,5. Define Histology.
A. Study of the body without a microscope
B. Study of tissues composed of cells and surrounding materials
C. Study of cellular chemistry
D. Study of anatomical anomalies
Correct ,,,answer,,,: B. Examines tissues, which are composed of cells and the
materials surrounding them
Rationale: Histology requires a light microscope to examine tissue structure and
organization .
6. Define Gross Anatomy.
A. Study of structures requiring an electron microscope
B. Study of structures that can be examined without a microscope
C. Study of cellular organelles
D. Study of chemical reactions in tissues
Correct ,,,answer,,,: B. The study of structures that can be examined without
the aid of a microscope
Rationale: "Gross" means large; gross anatomy involves visible structures that can
be seen with the naked eye .
, 7. How is the body studied in regional anatomy?
A. System by system
B. Area by area
C. Cell by cell
D. Function by function
Correct ,,,answer,,,: B. Area by area
Rationale: Regional anatomy examines all structures within a specific body region
(e.g., head, thorax) together .
8. How is the body studied in systemic anatomy?
A. Area by area
B. Cell by cell
C. System by system
D. Tissue by tissue
Correct ,,,answer,,,: C. System by system
Rationale: Systemic anatomy groups organs by function (e.g., skeletal system,
muscular system). BIOL 319 uses the systemic approach .
9. Define System.
A. A single organ with one function
B. A group of structures with one or more common functions
C. Any collection of cells in the body
D. A microscopic anatomical unit
with complete solutions.
