,UNIT 1 – INTRODUCTION TO ANATOMY AND PHYSIOLOGY (MODULE 1)
1. What is the study of the structure of the human body?
A) Physiology
B) Anatomy
C) Anabolism
D) Catabolism
Correct Answer: B
Rationale: Anatomy is the study of the structure of the human body and
its parts. Physiology is the study of the function of the body (A).
Anabolism (C) is the building up of molecules, and catabolism (D) is the
breakdown of molecules.
2. Which of the following is an example of the organ level of
organization in the human body?
A) Sodium
B) The liver
C) Mitochondria
D) The skeletal system
Correct Answer: B
Rationale: The liver is an organ composed of multiple tissues working
together. Sodium (A) is at the chemical level. Mitochondria (C) is at the
organelle level. The skeletal system (D) is at the system level.
3. What is the breakdown of nutrients called?
A) Anabolism
B) Metabolism
C) Catabolism
D) Homeostasis
,Correct Answer: C
Rationale: Catabolism is the breakdown of complex molecules into
simpler ones, releasing energy. Anabolism (A) is the building up of
molecules. Metabolism (B) encompasses both anabolism and
catabolism. Homeostasis (D) is the maintenance of a stable internal
environment.
4. Which of the following statements is TRUE concerning the
function of the skeletal system?
A) Sesamoid bones are large and thin
B) Bones are not completely smooth surfaces
C) A foramen is a projection for a tendon or ligament attachment
D) The two main divisions of the skeletal system are lumbar and
thoracic
Correct Answer: B
Rationale: Bones are not completely smooth surfaces; they have various
markings for muscle attachment, passage of blood vessels, and
articulation. Sesamoid bones (A) are small and round, not large and
thin. A foramen (C) is a hole, not a projection. The two main divisions
(D) are axial and appendicular, not lumbar and thoracic.
5. True or False: The skull protects the brain.
A) True
B) False
Correct Answer: A
Rationale: The skull (cranium) provides bony protection for the brain,
which is one of its primary functions.
6. What is the primary function of the skeletal system?
A) Gas exchange
, B) Protection and support
C) Nutrient absorption
D) Temperature regulation
Correct Answer: B
Rationale: The skeletal system provides protection for vital organs,
support for the body, and serves as attachment points for muscles. Gas
exchange (A) is a function of the respiratory system. Nutrient absorption
(C) is a function of the digestive system. Temperature regulation (D) is a
function of the integumentary system.
7. What is the role of osteoblasts?
A) Bone resorption
B) Bone formation
C) Blood cell production
D) Cartilage formation
Correct Answer: B
Rationale: Osteoblasts are bone-forming cells that synthesize new bone
matrix. Osteoclasts (A) are involved in bone resorption. Blood cell
production (C) occurs in red bone marrow. Chondroblasts (D) form
cartilage.
8. The liver is an example of which level of organization?
A) Cellular level
B) Tissue level
C) Organ level
D) Organ system level
Correct Answer: C
Rationale: The liver is composed of multiple tissue types working
together to perform specific functions, making it an organ. The cellular
